SMC HCL-HV2 Flight 7.4V/2S-4900mAh-90C LiPo Battery

HCL-HV2 4900mAh 7.4V 90C LiHV Battery - Reliable Power, Zero Sag

The HCL-HV2 4900mAh 7.4V LiHV battery is engineered for high-performance FPV drones and RC applications , delivering higher sustained voltage and an improved mAh-to-weight ratio without compromise. Unlike typical high C-rate batteries that trade capacity for power, this pack maintains a solid 4900mAh while pushing a 90C discharge rate —ensuring consistent performance, longer flight times, and minimal voltage sag under load.

With G10 top and bottom plates for added durability and 10AWG low-resistance wiring , this battery is built to handle high-current demands efficiently. Whether you're sending it in a race, freestyling, or running high-powered electronics, the HCL-HV2 delivers steady, reliable power when it matters most .
