high voltage high energy density UAV battery
Herewin high-voltage high-energy-density UAV batteries use LCO or blended LCO–NMC high-voltage cells to deliver a nominal cell voltage of 3.85V to 3.95V and an energy density of 280Wh/kg and above.
With large-format cell capacities of up to 67Ah, the battery platform can reduce the number of parallel cells and electrical connection points required in high-capacity UAV battery packs. This helps simplify pack architecture and supports more compact and reliable power-system integration.
The higher nominal cell voltage also enables a higher pack voltage with the same series configuration compared with conventional 3.7V lithium cells, providing a balanced solution for agricultural drones, heavy-payload UAVs, logistics drones and VTOL aircraft.

FAQs
If you notice significantly reduced flight time, power drops, or unexpected shutdowns, or see bulging, damage, or abnormal charging, the battery is likely aged and should be replaced.
It’s not recommended. Voltage levels, discharge curves, and connector designs may differ between brands. Mixing batteries can cause instability or damage. Always use original or certified compatible batteries.
