SMC Racing SMC5275-4S1P-EC5 HCL-HP 14.8V 5200mAh 75C Flight Pack EC5

The SMC Racing SMC5275-4S1P-EC5 HCL-HP is a 14.8V 5200mAh 75C 4S flight pack LiPo battery purpose-built for mid-size electric RC aircraft and 4S-powered vehicles. Part of SMC's HCL-HP line, this pack uses 100% LCO cathodes for maximum cycle life and consistent performance. The 75C continuous discharge rating provides consistent current delivery for high-power brushless motor setups, maintaining stable voltage and predictable throttle response throughout the discharge cycle.

Note: This is a standard LiPo pack — charge each cell to a maximum of 4.20V using a LiPo-compatible balance charger. Do not use LiHV charge profiles (4.35V/cell). G10 fiberglass top and bottom plates protect the cell stack without the full weight penalty of a hardcase, keeping the pack practical for flight applications.
