HCL-HV2 5900mAh 4S LiHV Battery - High Voltage, High Performance
The HCL-HV2 5900mAh 4S LiHV battery is not just another LiPo—it's a next-generation power source built to deliver higher voltage under load without sacrificing energy density. This 90C-rated powerhouse builds on the success of the original HCL-HV flight series , pushing the limits of performance with cutting-edge materials and an optimized power-to-weight ratio.
Unlike conventional 4.2V LiPo packs , the HCL-HV2 hits 4.35V per cell , offering more sustained power and a higher burst output without compromising capacity per gram. Whether you're racing, freestyling, or pushing long-range endurance flights, this battery delivers cleaner, more consistent power where it matters most.
