21700 S70 18000mAh 6S4P Li-ion FPV Battery Pack

Voltage 22.2V 丨High-Performance Long Range Drone Battery  |  280A Continuous 丨 560A Burst  |  Ultra-Low IR

S70 Product Overview

The S70 21700 Li-ion battery pack is designed for long-range FPV drones, cinematic UAVs, and high-efficiency endurance builds, delivering a rare balance between high burst power and stable long-duration discharge.

Unlike standard Li-ion packs, the S70 is engineered with high-current 21700 cells, optimized for real FPV flight conditions where voltage stability, discharge curve consistency, and thermal control directly affect flight performance.
