Battery Pack 6s3p SunPower 12000 mAh

The SunPower 6S3P 12000 mAh Li-ion battery pack is engineered for high-endurance UAVs, long-range FPV aircraft, and heavy-lift drones that require maximum flight time and consistent power delivery.

Built from premium SunPower 21700 cells, it provides high energy density and steady voltage output even under extended load. Its 6S (21.6 V) configuration with three parallel cells (3P) results in a total capacity of 12000 mAh, offering exceptional endurance without significant weight penalty.

Each pack is precision-assembled using copper busbars and spot-welding, ensuring low resistance and reliable current flow. Every unit is cell-balanced, capacity-tested, and enclosed in durable heat-shrink insulation for protection against impacts and environmental factors.

Ideal for long-range FPV systems, fixed-wing platforms, and reconnaissance UAVs, the pack delivers stable performance up to 120A continuous discharge, maintaining safe temperatures and consistent voltage throughout flight.
