350Wh/kg 6S 22.2V 15000mAh Drone Battery Suitable for Multi-Rotor Fixed-Wing Drones

Product Advantage

High Energy Density (350Wh/kg)

Significantly longer flight endurance than conventional LiPo at the same weight, ideal for long-range mapping and surveillance missions.

Dual-Platform Compatibility

Optimized for both multi-rotor (hover efficiency) and fixed-wing (sustained cruise) UAVs, simplifying inventory for mixed-fleet operators.

Large 15000mAh Capacity

Delivers 30–60 minutes of flight time depending on platform and payload, reducing battery swap frequency in the field.

Semi-Solid Safety

Non-leakage electrolyte minimizes thermal runaway and fire risks, ensuring stable operation under vibration, impact, and harsh outdoor conditions.
