Nexfly 6S 35,000mAh (35Ah) Solid-State Drone Battery — 2460g Standard
6S1P 35000mAh 22.2V
The Nexfly 6S1P 35,000mAh is a semi-solid state drone battery manufactured by Leolus Energy for professional UAV applications. Rated at 22.2V nominal voltage, this battery pack delivers high energy density, stable discharge performance, and advanced BMS protection for agriculture spraying, surveillance, mapping, and delivery drones.
It excels in both energy density and rate performance, supporting continuous high-rate discharge of 5C-10C, providing instantaneous high-current output capability for logistics drones. It supports 2C fast charging, with charging efficiency 35% higher than that of traditional solutions. Through solid electrolyte physical barrier and gel electrolyte curing technology, the risk of thermal runaway is reduced by 90%.

What this pack actually delivers
| Nominal voltage | 22.2V — 6S (22.2V) |
|---|---|
| Capacity | 35,000mAh (35Ah) |
| Stored energy | 777 Wh — voltage × capacity, the number that actually decides flight time |
| Pack weight | approx. 2,460g |
| Energy density | 316 Wh/kg — computed for this pack, not a best-case figure from elsewhere in the range |
The top of the range. Worth it only on airframes built for the weight; on anything lighter the extra grams cancel most of the extra energy. This is a heavy-lift and endurance choice, not a default upgrade.
What it suits
the working middle of Indian commercial UAV operations — agriculture spraying at 10–16L, mapping and survey platforms, delivery and surveillance airframes flying real duty cycles daily.
What it is not for
the heaviest spraying rigs and long-endurance BVLOS work, where 12S will hold voltage better under sustained load and leave more headroom at the end of the flight.
Before you order
This is the most common configuration we ship. If you are choosing between 6S and 12S, the deciding factor is usually all-up weight and how long you need to stay in the air, not capacity.
Send us your airframe, all-up weight with payload, and the flight time you need. A pack that is right on paper and wrong on the aircraft helps nobody, and we would rather tell you a smaller pack is the better fit than sell you the largest one in the range.
Customer reviews
