Lithium cells for drones & UAVs
Drone and UAV builders need high specific energy (Wh/kg) for endurance plus the discharge headroom for takeoff and aggressive maneuvers. Our 21700 high-rate cells — led by the 21700-40T (up to 15C, built for FPV and high-thrust UAVs) — and the 21700-40P high-power type target demanding surveillance, reconnaissance and industrial platforms, while lightweight 18650 high-power cells suit compact builds.
What matters for flight packs
- Specific energy (Wh/kg): drives flight time, and every gram counts.
- Continuous & pulse C-rate: enough headroom for takeoff and maneuvers.
- Low-temperature performance: stable discharge at altitude and in cold air.
- UN38.3 documentation: required for air freight of lithium cells.
Recommended series
21700 — the 40T (up to 15C) for FPV and high-thrust multirotors, the 40P high-power type for endurance with discharge headroom — and 18650 (lightweight, widest choice). Comparing the formats? See 18650 vs 21700.
