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 .
