HCL-HV2 4000mAh 3S LiHV Battery - Lightweight, High-Voltage Power

The HCL-HV2 4000mAh 3S LiHV battery is a high-performance, low-weight powerhouse designed for high-speed drones, power-hungry builds, and weight-sensitive applications . Building on the success of the original HCL-HV series , this 90C-rated LiHV pack delivers higher sustained voltage under load with a boost in capacity per gram , giving you stronger throttle response and reduced sag throughout your flight.

Unlike traditional 3S (11.1V) LiPo packs , this LiHV battery charges up to 11.4V (4.35V per cell) , meaning cleaner power, longer peak performance, and a noticeable increase in punch . Whether you're racing, freestyling, or pushing long-range missions , the HCL-HV2 4000mAh is built to keep up.

Key Features:

✔ True 4000mAh capacity (±5%) for extended performance
✔ 11.4V (3S, 4.35V per cell) LiHV chemistry - higher sustained voltage than standard 3S LiPos
