If you own a DJI FPV-class drone, you already know the number that annoys you. The pack on the marketing page promises 20 minutes of flight; the pack in your hands gives you 10 to 12 in the air before the return-to-home warning, and then it needs an hour on the charger before you can go again. That gap between the advertised figure and the real one is why searches for the best DJI FPV drones battery upgrades keep coming back to the same three answers, and why almost nobody out there has put them side by side in one place.
We spent six weeks working through every practical route to more airborne time on this platform, reading the mod logs, cross-checking the FPV community’s field reports and putting the ten products below through their specifications review by review. What follows is the honest ranking, including the parts nobody wants to hear: one of the three upgrade paths is a dead end for most people, and one of the products people assume is an upgrade is actually a cable.
There are only three real ways to get more flight time out of a DJI FPV drone, and we cover all three here. First, you buy more of the factory Intelligent Flight Batteries and build a rotation. Second, you move to a newer DJI FPV-class model whose packs last longer, no modification required. Third, you convert the battery bay to run standard 6S LiPo packs using a breakout board or a 3D-printed adapter. That third option is the one every forum thread is about, and it is the reason a lot of the products below exist.
One more thing worth stating up front: the original DJI FPV is no longer a current product, and the search results that still rank for this query are full of teardown logs and marketplace mod kits. The community has largely moved to the Avata and Avata 2 generation, which is where the battery maths is friendlier and where the packs on this list actually fit.
If you are still choosing the drone rather than the pack, start with our FPV racing drone picks and the DJI travel drone guide first, then come back here for the power side of the equation.

Two things stand out in that table before you read a single review. Every genuine DJI Intelligent Flight Battery on this list sits in the 2420mAh to 3750mAh class, and every third-party LiPo here is a 3S pack in the 11.1V class, because that is what a 4S bay expects. Nothing on this list is a 6S pack, and that is the single most important thing to understand about buying a battery upgrade for a DJI FPV-class drone: the smart-battery ecosystem is a closed loop, and almost nothing outside it will fit.
1. DJI Avata 2 Fly More Combo (3 Batteries) – Three Packs and a Hub in One Box
DJI Avata 2 Fly More Combo (3 Batteries), FPV Drone With Camera 4K
2150mAh per pack
Three Intelligent Batteries included
377 g airframe
4K/60fps 1/1.3-inch CMOS
Pros
- Three factory packs plus a two-way charging hub in one box
- 13 km transmission and 155 degree field of view
- Propeller guards make close-quarters flying practical
- Gimbal and camera covered for 12 months
Cons
- Around 15 minutes of real flight per pack
- Video link degrades badly under dense tree cover
- No compass or heading readout in the goggles
- Motion controller is imprecise for experienced pilots
This is the answer for most people, and the reason is simple. Rather than fighting the battery bay, the Avata 2 Fly More Combo changes what the bay contains: three 2150mAh Intelligent Flight Batteries and a two-way charging hub, bundled with the drone, the Goggles 3, a motion controller and a spare propeller set. There is no modification, no soldering and no calibration drama.
The airframe weighs 377 g and each pack is a 2150mAh lithium polymer unit. Owners consistently put real-world endurance at roughly 15 minutes per pack, which is still short by camera-drone standards but is a genuine step up from the 10 to 12 minutes the older generation delivers.
What we like most is the rotation math. Three packs in the box means three batteries cycling while you fly, and the two-way hub in the kit tops them up in sequence. For a pilot who was previously charging one pack overnight and flying it the next afternoon, that is the difference between a weekend hobby and a weekend habit.
The honest weaknesses are all in the review data. Owners repeatedly flag the video link dropping out under dense tree cover at low altitude, the absence of a compass or heading display in the goggles, and a tight field of view that fits larger faces poorly. The included motion controller also draws complaints from pilots who want spot turns.
What the three-pack bundle actually gets you?
The jump from one pack to three is worth more than the individual minutes suggest. A 15-minute pack on a three-pack rotation gives you roughly 45 minutes of flying before you are down to charging, and because the hub charges sequentially you can pull a finished pack out and put a fresh one in without rebuilding the kit.
It also removes the most common complaint in the Avata owner community, which is not about the drone at all. It is about running out of packs. If your flying pattern involves more than one battery per session, the marginal pack in this bundle costs far less than buying them one at a time.
Where this combo stops making sense?
It stops making sense if you already own an Avata or Avata 2 and you only need one more pack, because the bundle duplicates hardware you have. It also stops making sense for long-range pilots, because 15 minutes is not enough to reach and return from a distant objective under any realistic reserve calculation.
And it is the wrong answer entirely if you fly freestyle or racing hard. The prop guards that make this package beginner-friendly also add drag, and the conservative power profile is not what you want when you are punching a gap at full throttle.
2. DJI Avata Fly More Kit – Two OEM Packs and a Hub in One Purchase
DJI Avata Fly More Kit, 19.69″ L x 19.69″ W x 11.02″ H
2420mAh per pack
Two packs plus charging hub
35.71 Wh rated capacity
About 18 minutes rated
Pros
- Two genuine OEM packs and a four-slot hub in one bundle
- Cheaper than buying the two batteries and the hub separately
- Real-time battery status through the Intelligent Battery Management System
- Charge time drops sharply with a 65W USB-C charger
Cons
- Hub fills only one battery at a time despite four slots
- No wall charger or USB-C cable included
- Very slow with a low-wattage USB brick
- Batteries need one install in the drone to take their firmware update
The Fly More Kit is the version of the same idea aimed at people who already own a first-generation Avata. You get two 2420mAh Intelligent Flight Batteries and a Battery Charging Hub, which in practice means a doubling of your flying time the moment the box opens.
Rated capacity is 35.71 Wh per pack and DJI quotes roughly 18 minutes of battery life. Real flight time lands closer to 15 minutes, which the owner reviews describe as short, and it is the single most repeated note in the reviews for this kit.
The hub is where the criticism lands. Despite having four slots, it charges one battery at a time, which means the four-slot design is really about storage and sequencing rather than parallel throughput. Owners are blunt that pairing it with a weak USB brick turns a 20-minute top-up into a multi-hour job, and a 65W-class charger is close to mandatory.
Long-term owners also report that these packs still balance well and hold behaviour after years of heavy use, which is the strongest argument for OEM cells in any platform. The one process step that catches people out is that each battery must be installed in the drone once to receive its firmware update.
Why the two-pack route still beats one pack?
Because the constraint on a single-pack FPV session is not energy, it is turnaround. With one pack you fly, then wait. With two packs you fly back-to-back sessions while the first one charges, and because the hub tops up the fullest battery first, the pack that is closest to ready is the pack that gets finished first.
That sequencing matters more than it sounds. A hub that always finished the emptiest pack would leave you with two half-charged batteries and nothing to fly. This one does not do that, which is why owners call the hub a genuine improvement to the flying experience even while complaining about its single-channel design.
When to skip the kit entirely?
Skip it if you fly less than once a week, because two OEM packs will sit in storage doing nothing and storage is when lithium polymer cells age fastest. It is also poor value if you are chasing total endurance rather than session endurance, since the quoted 18 minutes is measured hovering in still air, not flying.
It is the wrong pick for long-range work for the same reason as the Avata 2: a single sub-20-minute pack caps your reach regardless of how good the rest of the kit is. For that use case, the 6S conversion route explained in the buying guide further down is the one that changes the maths.
3. Zeee 3S 2200mAh Shorty Pack – The Compact Choice for Tight Builds
Zeee 3S Lipo Battery 2200mAh 11.1V 50C Shorty Pack Battery with XT60 Plug for RC Car Truck RC Vehicles Boat Drone RC Airplane Quadcopter Helicopter FPV Racing Hobby Models(2 Pack)
2200mAh at 11.1V
3S1P configuration
137 g
75 x 34 x 26.5 mm
Pros
- Compact shorty form fits bays a standard 2200mAh pack will not
- 137g keeps weight and CG where you want them
- XT60 plug works across cars boats planes and quads
- Two-pack bundle is a cheap way to add spares
Cons
- Needs a genuine LiPo balance charger
- Charge rate should stay between 0.5C and 1C
- One isolated report of swelling after a few runs
- No telemetry for smart-battery platforms
Here is the thing most battery guides never say plainly: a 2200mAh 3S pack weighs 137 g in shorty format and around 168 g in full-size format, and that 31 g difference is often worth more to a pilot than a few extra minutes of runtime. The Zeee shorty does the same job as a standard pack in a fraction of the volume, which matters enormously in a tight FPV frame or a cinewhoop.
Specifications are 2200mAh, 11.1V, 3S1P, 50C discharge with an XT60 connector, measuring 75 x 34 x 26.5 mm and weighing 137 g. Owners across RC cars, crawlers, boats and small FPV craft report that the packs fit their compartments exactly and that several-year-old units still perform, provided they were maintained properly.
The balance-charger requirement is the honest catch. This is a dumb LiPo with no telemetry, no cell monitoring through the flight controller and no percentage reporting in the goggles. It needs a real balance charger at 0.5C to 1C, and it needs you to check voltages yourself before every flight.
That is also exactly why it works as a conversion component. Packs like this are what you fit into a DJI FPV bay after a 6S breakout mod, where the drone’s own battery reporting is spoofed anyway and all you need is a pack that delivers current reliably and weighs as little as possible.
Where the shorty form factor pays off?
In anything with a constrained battery bay, and that includes almost every 3-inch and 5-inch freestyle frame, plus ducted cinewhoop builds where internal volume is the limiting dimension. A 31 g saving on a small quad is a meaningful percentage of total weight, and lower weight directly extends hover time.
It also helps with centre of gravity. Packs of this size can be positioned further forward, which corrects the nose-heavy bias that many FPV frames have, and a forward-shifted CG means less throttle correction in a hover.
What you give up to get the compact pack?
You give up status reporting and you give up safety net. Without a smart battery there is no on-screen percentage to warn you, so the only warning is your own voltage check. There is also a documented report of a pack beginning to swell after a few runs, which is rare but is the failure mode that matters with lithium polymer.
Do not buy this as a drop-in for a DJI battery bay without a conversion. That bay is a smart-battery ecosystem, and nothing outside DJI’s own packs will be recognised by an unmodified drone. As a standalone pack for a conventional FPV build, or as the cell source for a modded bay, it is a strong pick.
4. DJI Avata Intelligent Flight Battery – A Single OEM Spare for Existing Fleets
DJI Avata Intelligent Flight Battery
3750mAh capacity
14.76V
0.16 kg per pack
About 18 minutes rated
Pros
- Genuine OEM pack the firmware recognises with no faking
- Rated 35.71 Wh for roughly 18 minutes
- Intelligent Battery Management System reports status in real time
- Reliable drop-in replacement for a factory pack
Cons
- Around 15 minutes of real flight per pack
- Costs more per pack than third-party LiPo
- Firmware update requires the pack to sit in the drone
- Not compatible with Avata 2 or other DJI platforms
Sometimes the correct battery upgrade is simply one more of the packs you already have. This is the single DJI Avata Intelligent Flight Battery, rated at 3750mAh and 14.76V, weighing 0.16 kg, and it is the answer for anyone running a three or four-pack rotation who has dropped to two.
What you are paying for is certainty. Owners of this pack repeatedly make the point that many look-alike DJI batteries are simply not recognised by the drone, and that a genuine pack behaves identically to the factory unit with no firmware faking, no adapter and no risk.
The Intelligent Battery Management System reports pack status in real time, which means voltage, cycle information and remaining capacity show up properly in the goggles. Rated capacity is 35.71 Wh with approximately 18 minutes of battery life, measured hovering without wind or interference, which is a lab figure rather than a field one.
Real flight time in the owner reviews sits closer to 15 minutes, and that shortfall is the most repeated line in the reviews for this product. The other recurring note is that a pack can arrive warehouse-used, so buying from a seller with a clear return policy matters more here than it would for a generic LiPo.
Why OEM packs still win on compatibility?
Because the drone treats the battery as a trusted node on the power bus. It verifies the pack, reads the cell data, enforces a temperature window and can refuse to arm the motors if something looks wrong. That refusal is exactly what frustrates people who want to fit third-party cells, and exactly what makes a genuine pack work first time.
For anyone whose priority is predictable sessions rather than maximum minutes, that reliability is worth more than a spec sheet improvement. For anyone whose priority is raw endurance per pack, it is not.
When one pack is the wrong amount of pack?
Single-pack purchases rarely solve a session-length problem on their own. One extra 15-minute pack extends a two-pack session from 30 minutes to 45, which is a real gain, but it does not change the fact that you are still swapping batteries mid-solo-flight if you fly long-range or cinematic lines.
It is also the wrong purchase for anyone on the Avata 2 platform, because the packs are not interchangeable across DJI’s FPV-class models. Check which generation your drone is before you commit, and note that the first-use firmware update only happens when the pack is installed in the aircraft.
5. OVONIC 3S 2200mAh – The Pack With the Longest Owner Track Record
OVONIC 3s Lipo Battery 50C 2200mAh 11.1V Lipo Battery with XT60 Connector for RC Airplane Helicopter Quadcopter RC Car Truck Boat(2 Packs)
50C label reads closer to 50A sustained
2200mAh at 11.1V
168 g
107 x 35 x 22 mm
Pros
- Owners report packs over two years old still charging and balancing
- No swelling even in demanding aircraft
- XT60 discharge and JST-XHR-4P balance plugs are industry standard
- Small footprint helps weight and CG on small frames
Cons
- 50C label is optimistic and reads closer to 50A sustained
- Not suited to freestyle quads or large EDF jets
- Older packs lose punch even while still working
The most useful claim in the review set for this product is not about runtime. It is that owners flying almost daily report zero swelling and continued good balancing after two years or more, which for a pack you are going to cycle hard outdoors is the metric that actually decides whether it was worth buying.
Specifications are 2200mAh, 11.1V, 3S, 50C discharge, with a JST-XHR-4P charging plug and an XT60 discharging plug in a soft case, measuring 107 x 35 x 22 mm at 168 g. The listing claims a 350-cycle life and up to 12 percent longer run time than a previous generation, though treat the marketing percentages with care.
The C-rating caveat is the one worth understanding. Owners consistently read the 50C label as roughly 50 amps sustained rather than 50 amps burst, which makes these a good fit for park fliers, small wings and 7 to 10 inch FPV craft, and a poor fit for high-current freestyle or large EDF models where burst current is what you are buying.
That honesty about discharge capability is refreshing, and it is the reason this pack still appears in community recommendations years after launch. Buy two, and you have a rotation that will probably outlast the frame it was bought for.
Reading the C-rating correctly before you commit
A C-rating is a multiplier on nominal capacity. On a 2200mAh pack, a 50C rating describes roughly 110 amps of theoretical discharge, but the realistic sustained figure depends on the cells inside and the cooling the pack gets, which in a small FPV frame is whatever airflow you can get.
The practical rule is to match sustained output to what your motors and ESC actually pull on a punchy throttle stab. A 50C 2200mAh pack is more than adequate for a 5 to 7 inch freestyle quad on moderate punches. It will feel soft on a full-throttle descent from altitude with a heavy camera, and that is a pack-matching problem, not a brand problem.
What longevity actually buys you?
It buys you the ability to keep a pack in rotation for years instead of seasons, which changes the cost maths entirely. A cheaper pack that lasts 40 cycles costs far more per cycle than a pricier pack that lasts 300, and on a platform where every flight burns a pack, cycles per pack is the number that matters.
The watch-outs are modest but real. Older packs lose punch even while still functioning, so keep at least one known-good pack as your benchmark. And the OVONIC dedicated balance charger is recommended, which is another reason to treat the charger as part of the purchase rather than an accessory.
6. DJI Avata 2 Two-Way Charging Hub – Making Three Packs Practical
DJI Avata 2 Two-Way Charging Hub, Compatibility: DJI Avata 2
Charges three packs in sequence
45 minute full charge
5 A output
USB-C power bank
Pros
- Charges three Avata 2 batteries sequentially so one is always ready
- About 45 minutes for a full charge with the 65W charger
- Also powers DJI Goggles and phones when no outlet exists
- Official accessory with correct firmware behaviour
Cons
- Charges one pack at a time rather than three in parallel
- Performance depends entirely on a 65W-class charger
- No charger or cable included with the hub
- Only charges Avata 2 Intelligent Flight Batteries
This is not a battery, and we would rather say so plainly than dress it up. The Avata 2 Two-Way Charging Hub is the accessory that makes a three-pack rotation workable away from a wall, and in practice it sets how long you can stay in the air before you have to pack down.
It takes three Avata 2 Intelligent Flight Batteries, charges them sequentially, and fills a pack in about 45 minutes when paired with the DJI 65W Portable Charger. It also doubles as a power bank, which owners point to as the feature that saves a field session when no outlet is available.
The confusion that shows up again and again in the reviews is whether the three slots charge at once. They do not. The hub fills one pack, then moves to the next, and anyone expecting a parallel three-way charge is going to be disappointed. Sequentially is still the right behaviour for a field kit, because you want one finished pack rather than three half-finished ones.
It weighs 0.11 kg and measures 3.93 by 5.59 by 1.46 inches, so it fits in a field bag without becoming the thing you leave at home. Output is 5 A at 17 V from a 20 V input, with USB Type-C connectivity.
Why charging speed sets your flight ceiling?
Because a rotation is only as good as its slowest link. Three 15-minute packs give you 45 minutes of flying, and the hub puts one finished pack back in the bag every 45 minutes. If you are using a 65W adapter, that works. If you are on a 20W phone charger, the same session becomes 45 minutes of flying and a very long afternoon of waiting.
The power bank function changes the same equation for your headset. The Avata 2 headset and the Goggles 3 both draw meaningful power over a long session, and being able to top them up from a flight battery rather than a car socket keeps you flying past the point where everyone else is packing down.
Where the stock hub falls short?
Parallel charging. If your flying pattern means you burn all three packs before you leave, sequential charging means you spend the rest of the session waiting. For that specific pattern, the faster third-party hub in this list does the same job in roughly half the wall time, and we cover it further down.
It also ships without a charger or cable, and it charges Avata 2 packs only, so if you run a mixed fleet of first-generation and second-generation hardware you are carrying two hubs or living without one.
7. RAWECUD Head Strap and XT60 Cable – Powering the FPV Goggles V2 from a LiPo
Head Strap and Power Cable XT60 for DJI FPV Goggles V2 Lipo Battery
XT60 to DC 25cm lead
Type-C to DC 30cm lead
5 A output
Adjustable headband with pocket
Pros
- Sturdier strap than the factory three-point band
- Elastic pocket holds a third-party pack on the headband
- XT60 lead opens up larger battery options for the headset
- Removes the cable that normally runs down into a pocket
Cons
- Only fits DJI FPV Goggles V2 and not Avata Goggles 2
- Battery pocket sits over the wearer's ear
- Goggles are not included
- This is a strap and cable accessory rather than a battery
Half of your FPV session is spent looking through goggles, and on the first-generation FPV Goggles V2 that means managing a battery and a dangling cable. This kit solves the cable half of that problem and, more importantly, opens up the power half.
You get an XT60 to DC adapter lead at 25 cm, a Type-C to DC replacement cable at 30 cm, and an elastic adjustable headband with a built-in pocket that fastens a LiPo or the original battery to the strap. Output is 5 A at 12 V, 60 watts.
The XT60 lead is the headline for anyone who cares about session length. Owners report strapping a larger 2S pack to the headband and getting meaningfully longer headset runtime than the factory pack, which turns a marginal headset into one that survives a full battery rotation without a mid-flight power cut.
Owners compare it favourably to the factory three-point band, noting the third top band becomes unnecessary once the battery is carried on the strap. The pocket is snug enough that the pack does not swing, which is a genuine improvement on a cable-only arrangement.
What the XT60 lead actually unlocks?
Any 2S pack with an XT60 connector, which in practice means a much wider choice of capacities than the single factory battery allows. Because the lead is a passive adapter, there is no negotiation with the headset about whether the pack is genuine, which is the opposite of how a drone battery bay behaves.
There is a trade-off: the pack is now on your head, so its weight is head weight rather than pocket weight, and a larger pack is more noticeable over a long session. For most pilots that is an easy trade against not re-plugging mid-flight.
Check your headset before you order
This kit is explicitly for the DJI FPV Goggles V2 and explicitly not for Avata Goggles 2. That limitation is stated plainly on the listing and repeated by owners who ordered the wrong one, so match the model before anything else.
Also manage expectations: the battery pocket sits over the ear rather than further back on the head, and a few owners find that uncomfortable over long sessions. And to be explicit, this package does not include a battery. If you have no spare 2S pack, buy one of the XT60 packs in this roundup alongside it.
8. RAWECUD Avata Goggles 2 Bracket – A Battery Mount That Stops the Swinging
RAWECUD Power Cable and Battery Bracket for DJI Avata Goggles 2 Combo
30cm power cable
PC battery bracket
Micro USB Type B
20 g total
Pros
- Clips the Avata Goggles 2 battery snugly onto the headband
- 30cm lead is a welcome short replacement for the long original
- Lightweight PC bracket adds almost no mass to the headset
- Several owners bought it specifically to replace a failed cable
Cons
- 30cm lead is short enough to hang past the right ear
- Goggles are not included
- Only fits the DJI Avata Goggles 2
- Includes no battery and no charging capability
This is the Avata Goggles 2 equivalent of the previous kit, and it is the fix for two specific annoyances: the original power cable being too long, and the battery bouncing around on the side of the headset.
You get a PC battery bracket that clips onto the headband and a 30 cm PVC power cable that connects the battery to the headset. The connection is USB 2.0 Micro B at the headset end, and the whole assembly weighs about 20 g.
Owners who bought it to replace a coiled cable that had failed internally describe it as a genuine repair rather than a workaround. Locking the battery to the headband also frees pocket space and stops the cord snagging, both of which matter when you are carrying several packs to a field.
The bracket fits tightly at both ends, which is exactly what you want on a headset that sees a lot of movement in freestyle and cinematic work. Adding a rigid mount rather than a strap means the pack does not swing, and a pack that does not swing is one that is less likely to get knocked loose.
Why a short cable beats a long one here?
Because the cable is only there to bridge a few centimetres between a battery on your head and a port on your head. The long original is slack that has to be managed, coiled, or tucked, and every version of that management is something that can snag.
A 30 cm lead removes the loop entirely. The cost is that it is short enough on some head sizes to drape past the right ear, which is the most common complaint in the reviews and the only real one worth weighing before you order.
Where this is not an upgrade?
It is not a battery and does not add any flight time. If your problem is endurance, this does nothing for it, and you should be reading the pack and hub sections instead.
It is also model-specific in the other direction. The FPV Goggles V2 needs the XT60 kit earlier in this list, and these two products are not interchangeable despite looking similar. Match the headset first, then pick the cable standard that matches how you want to power it.
9. TATTU 3S 1800mAh 45C – The Pack That Still Fits 250-Class Frames
TATTU 11.1V 1800mAh 3S 45C LiPo Battery Pack with XT60 Plug for Skylark M4-FPV250 Mini Shredder 200 INDY250 Plus MOJO 280 QAV250 Vortex Emax Nighthawk 250 RC Heli Airplane UAV Drone FPV
1800mAh at 11.1V
45C discharge
158 g
107 x 35 x 21 mm
Pros
- Fits the classic 250-class FPV frames it is listed for
- Japanese and Korean lithium polymer raw materials
- Long cycle life of at least 150 charges
- Light 21mm profile helps keep weight down on small quads
Cons
- 1800mAh gives less endurance than 2200mAh packs
- 45C rating is modest for freestyle or high-current builds
- Sold as a single pack so you need more than one
- Requires a separate 3S LiPo balance charger
Every modern pack on this list is too big for some of the frames that are still in daily use. The TATTU 3S 1800mAh 45C is 107 x 35 x 21 mm and weighs 158 g, which is the size that fits the older 250-class FPV frames it is listed against, from the Skylark M4-FPV250 to the QAV250 and the Emax Nighthawk 250.
The build is what you are paying for here. TATTU specifies Japanese and Korean lithium polymer raw materials, a cycle life of at least 150 charges, and an energy density of up to 200 Wh/kg. Owners report fast recharging and stable balance over repeated use.
The honest limitation is capacity. 1800mAh is 18 percent less than a 2200mAh pack of the same class, and on a 250-class quad where flight time was never generous, that difference is a full minute or more of hover. If your frame has the space, buy the 2200mAh packs instead.
When 1800mAh is the right number?
When the frame physically will not take a larger pack, and that is more common than the marketing for modern quads suggests. A 21 mm thickness against a 22 mm full-size pack is the difference between fitting with a little room and not fitting at all, and in older frames that space is measured in millimetres.
It is also the right pick if you are buying a pack for a long tail of older aircraft rather than one hero build. A standard capacity and a standard connector means it drops into whatever you have without a custom order, which is worth more than a few extra minutes when the aircraft changes every season.
What a 45C rating means on this pack?
On 1800mAh, 45C describes roughly 81 amps of theoretical discharge, and as with the other budget packs here the honest reading is that sustained output is lower than the burst figure suggests. That is fine for 250-class park and line flying, and marginal for hard freestyle punch-outs on a heavy quad.
Two more things to plan around. It is a single pack, so a rotation means buying multiples, and it needs a 3S balance charger which you should budget for separately. Owners generally rate the value highly for the money, but the value only shows up if you buy the charger too.
10. LKTOP 100W Avata 2 Charging Hub – Parallel Charging for Long Days
LKTOP 100W Replacement DJI Avata 2 Battery Charging Hub (2X Super Fast)
100W output
Three packs in about 70 minutes
Sequential and parallel modes
LCD and app readout
Pros
- Fills three Avata 2 batteries in about 70 minutes
- Sequential and parallel modes plus a 60 percent storage mode
- Works as a power supply for the controller and phone
- LED screen and app show cycle count and charge level
Cons
- No power adapter included so bring your own 65W or 100W supply
- A 45W brick makes the unit appear completely dead
- Battery slots are poorly supported so packs can pop out
This is the counter-argument to the official hub. Where the DJI unit fills one pack at a time, this 100W hub can take all three Avata 2 batteries in parallel and finish them in about 70 minutes, which for a full day of flying is a real throughput difference.
It also adds what the official hub lacks: a display and a companion app. Owners read per-battery charge level, wattage, cycle count and manufacturing date directly off the LCD, which is exactly the information you want when you are deciding whether a pack has reached the end of its useful life.
There is a 60 percent storage mode for packs that will sit unused between trips, and a power bank function that charges the remote controller, an action camera or a phone over USB-C. The six listed protections cover over-temperature, short-circuit, over-voltage, under-voltage, over-current and over-power.
The 4.2 average is honest, and it comes from two specific issues rather than general dissatisfaction. The first is that no adapter is included, so with a 45W or weaker supply the unit looks completely dead and owners genuinely thought it was broken. The second is a cluster of durability reports where charging stopped working after a few months.
When parallel charging actually pays?
When you burn all three packs before you stop. Sequential charging serves a session where you fly an hour, recharge one pack, and leave with a usable spare. Parallel charging serves a shoot day where the rotation is the working unit and you need all three ready before the next location.
There is also a neat trick owners use: two of these hubs charge six Avata 2 batteries at once, which is the arrangement that makes a multi-pilot or multi-aircraft day workable. The power bank function is the quiet extra, since it tops up a controller and a camera from a flight battery when the car is the only outlet available.
What to buy alongside it?
A 100W USB-C PD 3.0 adapter. This is not optional, it is the difference between a fast hub and an inert box, and the 1-star reviews in this set are overwhelmingly about a supply that was too small. Ideally you also budget a second one so you are not carrying the hub without a way to power it.
Then check the fit of the slots, which owners describe as not well supported. A pack that pops out mid-charge stops charging and, in a car at a remote location, that is a wasted day. Treat this as the specialist option for high-pack-count days rather than the default hub, and keep the official unit as the dependable fallback.
How to Choose a DJI FPV Battery Upgrade?
Which of the three upgrade paths you actually need?
Path one is buying more OEM Intelligent Flight Batteries. It is the safe, fully supported route, it keeps warranty and telemetry intact, and it is the right answer if you fly in built-up areas, in the United States, or anywhere requiring a registered drone with an approved battery configuration. Path two is moving to a newer DJI FPV-class model, which is the only route that changes the ceiling rather than adding to it. Path three is converting the battery bay to standard 6S LiPo, which is the enthusiast route and the one every mod kit in this category exists to serve.
There is a fourth option people rarely mention: doing nothing to the battery and reducing weight, improving technique and buying better chargers. Later in this section there is a list of those changes, and for a surprising number of pilots they recover as much time as any pack swap at no cost and no risk.
What a C-rating really means on a 6S pack?
A C-rating multiplies capacity to give a current figure. A 6S 1500mAh pack labelled 150C describes roughly 225 amps in theory, but the real sustained output is a property of the cells inside and the cooling available, not of the label. Community consensus treats labelled 150C and 180C ratings as burst figures and budgets around a fraction of them for planning.
For flight time specifically, the C-rating matters far less than capacity and weight. A pack with a modest rating and a high capacity will fly longer than a high-rating pack that weighs twice as much, because every extra gram is carried for every minute of the flight. Only when you are punch-throttling does the rating become the limiting factor, and that is a burst-duration question rather than an endurance question.
Weight is the number that decides your flight time
This is the part of the maths that most buying guides skip. The r/fpv community treats the CNHL 1300mAh 6S Black Series pack, at roughly 230 g, as its lightweight standard, and r/fpv pilots average 4 to 4.5 minutes per pack on 5-inch builds. The same forum reports a modded DJI FPV with a 1300mAh SMC pack recording a 6:30 flight with 45 percent remaining and 508 g total weight including the battery.
That is the trade in one line. Extra capacity buys endurance and costs flight time proportionally to the weight it adds, so the efficient packs sit in a band, not at an extreme. A 4000mAh 6S pack is the clearest example of the trap: a Facebook FPV group pilot reported a flight that landed after 7 minutes with 3.95V per cell still remaining, because the pack was simply too heavy to fly far on what it held.
Our internal guide to 4S FPV drone batteries covers the same capacity-to-weight trade in more detail if you are running conventional 4S builds rather than a DJI platform.
The calibration cycles nobody warns you about
Here is the failure mode that catches first-time modders. A DJI smart battery is a control board plus cells, and the board keeps a running account of the charge state. Disconnect the cells, or substitute a different set, and that account is wrong. The drone then refuses to arm the motors.
The documented fix is patience. A modded install typically needs 2 to 4 full charge-discharge-charge cycles before the percentage reading in the goggles OSD becomes meaningful, and one forum commenter described the interim reading as showing the weather. If you land a pack at a reported 4 percent that is actually full, and then launch on a reported 90 percent that is nearly empty, the risk is real, so treat the first few flights as short.
On batteries that report through a 6S breakout board, the same guidance applies. The board spoofs what the drone expects to see, and the drone’s own accounting needs to settle before the numbers mean anything.
Getting more flight time with no modification at all
Start with weight. Every 10 g removed from a 5-inch build is roughly 10 g the motors stop lifting for every minute of the flight, and the cheapest grams to remove are the ones you never needed: excess camera cable ties, a heavier camera than the frame was designed around, an unnecessary canopy bolt. Set a 30 g target before you start.
Next, look at cruise speed. Most pilots hover and hold altitude far more than the flight actually requires, and altitude is expensive because the motors work continuously against lift. Flying a smooth line at constant altitude and constant speed, instead of climbing and descending, is the single biggest free gain available to any pilot.
Then, charge and store properly. Lithium polymer cells that sit at full charge degrade faster than cells stored around 60 percent, and the storage mode on the LKTOP hub earlier in this list exists for exactly this reason. Never charge unattended, keep packs away from heat, and retire any pack that puffs rather than trying to squeeze one more flight from it.
Finally, practice return-to-home discipline. A conservative reserve costs you a small amount of usable time every flight and saves the whole pack’s remaining value, which over a season of regular flying is the difference between owning three packs and owning six.
LiPo safety and the DJI warranty question
Do not open a DJI smart battery casually. The cells are held under tension by a rigid case, and a case that has been pried open can vent violently. If you are going to work on one, work on a pack you have already accepted the loss of, outdoors or in a fire-resistant container, with eye protection and LiPo-safe tools within reach.
On the warranty question, be realistic. Modifying the battery bay voids any expectation of coverage on the aircraft, and a crash caused by a third-party cell is exactly the situation a manufacturer will decline to cover. The mod route is a hobbyist decision with a hobbyist risk profile, and the only way it makes sense is if you accept that before you start.
One more practical note from the communities: crashed packs can lock out with an error code rather than failing visibly, and a locked pack cannot be brought back by charging it. Retire damaged packs to proper battery recycling, never to household waste, and never fly a pack you have had to physically compress to fit back into a bay.
If your flying has moved towards longer routes, our FPV racing drone roundup covers the frames built for that kind of pace, and the FPV simulator guide is the cheapest way to practise the reserve discipline above before you commit airtime to it.
Frequently Asked Questions
Can I use a non-DJI battery in my DJI FPV?
Not without conversion. The drone verifies the battery over a proprietary multi-pin connection and refuses to arm the motors if the data does not match what it expects. To run a third-party pack you need a breakout board or a 3D-printed 6S adapter that intercepts that conversation, which is a soldering-level modification and voids any expectation of aircraft warranty coverage.
Why was DJI FPV discontinued?
The original DJI FPV is no longer a current product, and the search results that still rank for battery upgrade questions are built around old teardown logs and marketplace mod kits. DJI shifted the FPV-class line toward the Avata and Avata 2 generation, which use different Intelligent Flight Batteries with a protected prop guard and a motion controller. The practical consequence is that new OEM packs for the old platform are increasingly hard to justify, which is part of why the community moved to 6S conversion.
Is 6S more efficient than 4S?
For the same power output, 6S runs its motors at a lower current, which reduces resistive losses in the wiring and the ESC. On a well-matched build the difference is real but modest, and it is not the reason 6S conversions are popular. The reason is capacity: a 6S 1300mAh pack holds more energy than a 4S pack of similar weight, and that energy is what extends the flight.
How long should a 6S battery last?
In charge cycles, a good 6S LiPo should deliver 300 or more, and the packs in this roundup carry claims from 150 cycles at the budget end to 350 at the established end. In storage terms, keep lithium polymer packs at around 60 percent charge, away from heat, and retire any pack that puffs. A pack that is stored full will age noticeably faster than one that is stored part-charged.
What type of battery is best for long-range FPV drones?
For long-range work, prioritise energy density and honest weight over burst C-rating. The community standard is a 6S pack in the 1300mAh to 1500mAh range, which is where the weight-to-endurance trade works out best. Very high capacity packs look attractive on paper but are frequently too heavy to fly the distance their capacity implies, with pilots reporting 6S 4000mAh flights landing after about 7 minutes with voltage still high in the cells.
Final Verdict on DJI FPV Battery Upgrades
The best DJI FPV drones battery upgrades come down to one honest question: do you want more packs, a better platform, or a bigger pack. The DJI Avata 2 Fly More Combo is our top pick because it is the only option that changes the ceiling rather than working around it, giving you three genuine 2150mAh Intelligent Flight Batteries, a charging hub and roughly 15 minutes of real flight each with no modification and no calibration cycles.
Take the DJI Avata Fly More Kit if you already fly the first-generation Avata and want to double your session length for less than buying the parts separately. Take the OVONIC 3S 2200mAh for anything you build yourself, where the two-year pack life is worth more than the label. And if you are set on a 6S conversion, buy the adapter first, the pack second, and expect 2 to 4 charge cycles before the percentage readout in your goggles means anything.
Whichever route you take in 2026, the free gains are still on the table: cut 30 g, fly a cruise line instead of a hover, and store your packs at 60 percent. Those three changes cost nothing and return minutes on every single flight, which is more than most battery purchases will do for you.
