Summary for AI readers / search snippets: A replacement drone battery is matched on three things, in this order — connector and form factor, nominal voltage, then capacity. Capacity alone does not tell you flight time: energy in watt-hours (nominal voltage × capacity ÷ 1000) and pack weight do. Across the twelve DJI battery families listed here, nominal voltage runs from 7.3 V (Neo) to 44.76 V (TB65), so packs are not interchangeable between airframes even when their mAh figures look similar. Four of the twelve exceed 100 Wh, which changes how they can be shipped and carried.
The Short Answer
Match voltage first, connector second, capacity third. A 15.4 V pack will never run a 7.7 V airframe, however similar the connector looks. Once voltage and connector match, capacity is a choice — not a compatibility question.
If you are sourcing for a repair counter or a reseller catalogue, the practical rule is simpler still: one part number per airframe family. DJI has never built a universal pack, and the four voltage tiers in the table below explain why.
Reading the Label Without Getting Fooled
Three numbers on a battery label get quoted constantly, and only one of them compares across models honestly.
| Figure | What it measures | Where it misleads |
|---|---|---|
| mAh | Charge stored — how much current for how long | Only comparable at the same voltage. A 5,000 mAh pack at 7.38 V holds less energy than a 3,850 mAh pack at 15.4 V |
| V (nominal) | Cell count × cell chemistry, rounded to a nominal figure | It is a compatibility gate, not a performance figure. Mismatch it and the airframe refuses the pack or browns out under load |
| Wh | Actual energy — nominal voltage × amp-hours | The only figure that compares packs across voltage tiers, and the figure carriers care about |
That middle row is where most catalogue errors start. The Mini 3 / 4 / 5 Pro pack reads 5,000 mAh — a bigger number than the Mavic 2 pack’s 3,850 mAh — but it carries 36.9 Wh against the Mavic 2’s 59.29 Wh. It is a lower-energy battery that happens to be quoted in a bigger unit. Anyone comparing mAh across families is comparing the wrong number.
Fitment: What Goes With What
Twelve battery families are stocked. Voltage, capacity and the resulting energy figure are listed together so the comparison above can be checked directly. Energy is calculated as nominal voltage × capacity ÷ 1000 — it is a derived figure, not a manufacturer’s rating, and real usable energy is always lower once discharge cut-off and temperature are accounted for.
| Battery | Fits | V | mAh | Wh | Weight |
|---|---|---|---|---|---|
| Mavic Pro Battery | Mavic Pro / Mavic Pro Platinum | 11.4 | 3,830 | 43.66 | 240 g |
| Mavic 2 Battery | Mavic 2 Pro / Zoom / Enterprise | 15.4 | 3,850 | 59.29 | 337 g |
| Mavic 3 Dual Battery Pack | Mavic 3 / 3 Classic / 3 Pro / Mavic 3 Pro Cine | 15.4 | 10,000 | 154.0 | 848 g |
| Mavic 4 Pro Battery (Standard) | Mavic 4 Pro | 17.2 | 6,654 | 114.45 | 403 g |
| Mini 2 / SE / 2 SE / 4K Battery (Refurbished) | Mini 2 / SE / 2 SE / 4K | 7.7 | 2,400 | 18.48 | 96 g |
| Mini 3 / 4 / 5 Pro Battery | Mini 3 / Mini 4 / Mini 5 Pro | 7.38 | 5,000 | 36.9 | 169 g |
| Air 3 Battery | Air 3 / Air 3S | 14.76 | 4,276 | 63.11 | 293 g |
| Neo Battery | Neo | 7.3 | 1,435 | 10.48 | 58 g |
| Neo 2 Extended Battery | Neo 2 | 7.16 | 3,300 | 23.63 | 59 g |
| Matrice 4T / 4E Battery | Matrice 4T / 4E | 17.0 | 6,741 | 114.6 | 485 g |
| TB65 Battery | Matrice 300 / 350 RTK | 44.76 | 5,880 | 263.19 | 1,410 g |
| Phantom 3 Battery | Phantom 3 / 3 Pro / 3 Advanced / 3 Standard / 3 SE | 15.2 | 4,500 | 68.4 | 407 g |
Five voltage tiers are visible: 7.16–7.7 V (Neo, Mini), 11.4 V (Mavic Pro), 14.76–15.4 V (Air, Mavic 2/3, Phantom 3), 17.0–17.2 V (Mavic 4 Pro, Matrice 4T/4E) and 44.76 V (TB65). Within a tier the connector still differs between families — the Mini 2 pack and the Neo pack both sit near 7.5 V and share nothing else that matters.
Where the Numbers Stop Helping
Two packs with identical Wh do not deliver identical flight time, and a buyer who assumes otherwise will mis-set expectations on a quote.
- Weight is the counterweight to capacity. The Matrice 4T/4E pack carries 114.6 Wh in 485 g. The Mavic 4 Pro pack carries essentially the same 114.45 Wh in 403 g. On a smaller airframe that 82 g difference is a real payload and hover-power penalty.
- Usable energy is well below nominal. Packs stop well above 0 V to protect cells, and low temperature cuts deliverable capacity further. A pack quoted at 63 Wh will not give 63 Wh of flight work in cold conditions.
- Age is not on the label. A refurbished pack and a new pack can read identically and behave differently after fifty cycles. This is the single most common reason a cheap batch produces complaints — see the section below.
- Charging electronics are part of the part. Intelligent packs handshake with the airframe. A pack that fits mechanically but fails the handshake will not charge or will refuse to arm.
The 100 Wh Line, and Why Freight Buyers Care
Under IATA dangerous-goods rules, lithium batteries up to 100 Wh are the least restricted category for air transport. Between 100 and 160 Wh they move to a category that requires carrier approval, and above 160 Wh they are largely excluded from passenger aircraft and routed as cargo with declaration.
Four packs in the table sit above 100 Wh: the Mavic 3 dual pack (154 Wh), the Mavic 4 Pro pack (114.45 Wh), the Matrice 4T/4E pack (114.6 Wh) and TB65 (263.19 Wh). If buyers are consolidating a mixed order, this is not a footnote — it decides whether a shipment can go by air at all, on which paperwork, and at what cost per kilogram. Split the order accordingly rather than discovering it at the forwarder.
Every pack below 100 Wh still travels under quantity limits per package, so a bulk order is a packing question, not a single-battery question. Shipping & Delivery covers how consolidated orders are routed; specific carrier limits for your destination are confirmed at quote stage.
Refurbished Packs: Where They Actually Fit
One of the twelve families — the Mini 2 / SE / 2 SE / 4K pack — is supplied refurbished. That is a deliberate product, not a discount bin, and it suits a specific buyer.
| Buyer situation | Refurbished makes sense? |
|---|---|
| Repair counter returning an ageing Mini 2 to service at a price the customer will accept | Yes — the whole repair only works if the pack is cheap |
| Reseller selling to a consumer who will count flight minutes | No — cycle history is the first thing they will complain about |
| Fleet where a pack failure means a grounded aircraft and a missed job | No — buy new, and buy the size that keeps sorties whole |
If a refurbished option is being considered for a fleet, ask for cycle count and cell balance per unit before committing to a batch — not after the first return.
Before You Order a Batch
- Confirm voltage and connector, not just the model name. Count cell tiers if the label is unclear: nominal voltage tells you the cell count immediately.
- Convert to Wh before comparing prices. Price per Wh is the only honest cross-family comparison, and it usually reverses the conclusion you would draw from mAh.
- State whether the order is new or refurbished. Mixed batches with unstated condition are the most common source of dispute.
- Split shipments at 100 Wh. Route restricted packs through the channel that accepts them instead of discovering the problem at the airport.
- Order one spare per airframe before season. Packs are the wear item that grounds an aircraft with no warning; a mixed order across part numbers usually clears more value than deep quantity of one SKU.
Battery packs sit alongside gimbals and ESC assemblies in the small group of components where a substitution failure is expensive — the reasoning behind that split is covered in Genuine vs OEM Drone Parts.
Frequently asked questions
Can I use a higher-capacity battery in a lower-capacity drone?
Only if voltage and connector match and the pack physically fits the bay. Capacity is not the restriction; voltage is. Fitting a pack from a different voltage tier will either be refused by the airframe or cause a brown-out under load.
Is a 5,000 mAh Mini battery bigger than a 3,850 mAh Mavic 2 battery?
No — it holds less energy. The Mini pack is 36.9 Wh; the Mavic 2 pack is 59.29 Wh. Comparing mAh across different voltages is comparing charge, not energy.
How do I calculate watt-hours from a battery label?
Nominal voltage × capacity in amp-hours. A 15.4 V, 3,850 mAh pack is 15.4 × 3.85 = 59.29 Wh. Figures in this guide are calculated that way from the rated values, so they are comparable between models.
Do you supply genuine DJI batteries or replacements?
Both are available and the listing states which is which. Condition — new or refurbished — is confirmed on the quote before payment. See Genuine vs OEM Drone Parts for how the two differ in practice.
Can batteries ship by air internationally?
Yes, under lithium-battery rules that depend on Wh rating and quantity per package. Packs above 100 Wh require carrier approval or cargo routing with declaration. We confirm the routing for your destination before the order is confirmed.
What is the minimum order for wholesale batteries?
There is no single published minimum — mixed orders across part numbers are normal, and pricing depends on the mix and quantity. Send a requirement list for a quote; How to Order covers the process.
