HCL-HV2 2900mAh 3S LiHV Battery – More Voltage, More Power, Less Sag

The HCL-HV2 2900mAh 3S LiHV battery is built for pilots who demand higher sustained voltage, rapid power delivery, and minimal weight. An evolution of the original HCL-HV series, this 90C-rated LiHV pack delivers 4.35V per cell (11.4V total)—meaning better efficiency, snappier throttle response, and less voltage drop under load.

Whether you’re freestyling, racing, or flying high-performance drones, this battery keeps your quad powered with consistent, reliable output. Lighter than most 3S LiPos, but packing more punch, the HCL-HV2 2900mAh is designed to keep you in the air longer, with more power when you need it most.

Key Features:

✔ True 2900mAh capacity (±5%) for reliable flight performance
✔ 11.4V (3S, 4.35V per cell) LiHV chemistry – provides higher sustained voltage than standard 3S LiPos
✔ 90C discharge rate – instant, high-power output with minimal sag
