Battery Pack 6s4p SunPower 16000 mAh

The SunPower 6S4P 16000 mAh Li-ion battery pack delivers maximum energy density and consistent current output for long-range FPV drones, fixed-wings, and endurance UAVs.

With its 6S4P configuration (24 cells), the pack provides a nominal 21.6 V and a total capacity of 16000 mAh, offering up to 30–35 % longer operation time compared to 6S3P builds. Each SunPower 21700 cell features low internal resistance and high discharge stability, making it suitable for sustained high-load operation.

Built using copper busbars and precision spot-welding, the pack ensures low voltage drop and improved efficiency. It includes XT60 or XT90 power connectors and a JST-XH balancing lead, wrapped in heat-shrink insulation for safety and durability.

This battery is ideal for large FPV drones, long-range wings, and hybrid UAV platforms, where endurance and reliability are critical.
