SMC HCL-RS Series 2S 4000mAh 150C 7.4V Shorty LiPo Battery

Race ready and engineered for competitive RC racing performance, the SMC HCL-RS Series 2S 4000mAh 150C 7.4V LiPo Battery delivers stable voltage, strong discharge capability, and dependable power in a compact race-focused package. Part of SMC’s High Cycle Life – Race Series (HCL-RS), this low-center-gravity shorty pack is optimized for tracks where weight placement, handling, and voltage consistency matter most.

These race-spec cell formulations were developed specifically for high-demand on-road and off-road racing applications by an independent factory — not generic cells with repurposed labels. While high mAh and extreme C-rates are common in flight and speed-run packs, competitive racing requires a different kind of performance. SMC’s HCL-RS formulas focus on reducing internal resistance and maximizing usable capacity per cubic centimeter, holding voltage under load and reducing sag for consistent power delivery from green to checkered.

The Shorty LCG configuration keeps weight low and centered in the chassis, improving handling and balance without sacrificing race-day performance.
