What do the two packs hold?
The 14S pack holds 40,000mAh at 53.9 V nominal, for 2156 Wh of energy, with a 10C continuous discharge rate.
The 6S pack holds 36,000mAh at 22.2 V nominal, for 799.2 Wh of energy, with a 10C rate and 300 A max current.
The 14S pack weighs 8.55 kg and measures 240 x 164 x 107 mm, with an AS150U connector as pictured.
The 6S pack weighs 2.6 kg and measures 217 x 90 x 67 mm, and the listing asks buyers to confirm the connector before ordering.
How is energy density counted here?
The listings state 260 Wh/kg for the 14S pack and 330 Wh/kg for the 6S pack, and those are the listing figures.
Dividing listed energy by listed weight gives a pack-level figure: 2156 Wh divided by 8.55 kg equals about 252 Wh/kg.
The same math for the 6S pack gives 799.2 Wh divided by 2.6 kg, which equals about 307 Wh/kg.
The next highest computed figures in the shop are 178.6 Wh/kg and 178.2 Wh/kg.
The 178.6 figure is the Tattu 6S 7000mAh pack, and the 178.2 figure is the Zeee 3S shorty pack.
The other Zeee and Ovonic packs compute to 124.7 to 166.1 Wh/kg by the same math from their listing figures.
On computed pack-level numbers, these two packs hold the highest energy density among the batteries compared in this guide.
Which airframes do the listings name?
The 14S listing names heavy-lift multirotor, single-rotor, fixed-wing, and VTOL drones for spraying, surveying, inspection, firefighting, and cargo work.
The 6S listing names single-rotor, multi-rotor, fixed-wing, vertical take-off, and cargo drones for survey, firefighting, inspection, and agricultural work.
Match the pack voltage to the airframe rating: 53.9 V nominal for the 14S pack and 22.2 V nominal for the 6S pack.
Use a qualified smart charger only.
Respect the listing charge limits: 60.9 V max and 2C max for the 14S pack.
The 6S pack limit is 22.5 V max and 2C max.
What condition are these packs in?
The 14S pack has 0 cycles, is tested and stored, and is brand new with the plastics still on it.
The connector on the 14S battery is the same plug shown in the picture, as the listing states.
The 6S packs have 0 cycles and are brand new, with two packs in stock, and one 14S pack in stock.
Both packs are kept in the secure warehouse and checked regularly, and both are brand new.

How do you check fit before ordering in 5 steps?
- Confirm the airframe voltage rating matches the pack: 53.9 V nominal for 14S or 22.2 V nominal for 6S.
- Check the pack size and weight against the airframe battery bay and payload limit.
- Confirm the connector: AS150U as pictured on the 14S pack, and contact us to confirm the connector on the 6S packs.
- Confirm your charger is a qualified smart charger that covers the pack voltage and the 2C charge limit.
- Confirm storage voltage on the charger: 52.5 V to 53.9 V for the 14S pack, as the listing states.
