MACH-1 Racing Stealth Series 2S 4400mAh ULCG Shorty 140C 7.4V LiPo Battery

The MACH-1 Racing Stealth Series 2S 4400mAh ULCG Shorty 140C 7.4V LiPo Battery is the perfect choice for racers seeking lightweight performance and consistent power delivery. Weighing just 155 grams, this ultra-low center of gravity shorty pack is significantly lighter than standard LiPo and LiHV shorty batteries—delivering better handling and overall efficiency.

Built for serious 2WD and 4WD 13.5 or modified off-road racing, this pack offers improved runtime, lower operating temperatures, reduced internal resistance, and increased voltage stability throughout your run. The result? A more consistent, high-performance battery that meets the demands of competitive racing.

MACH-1 RACING LiPo packs are engineered with advanced cell chemistry that supports high charge rates while maintaining long-term durability. When charged at 0.5C to 1C, these batteries offer up to double the cycle life. Thanks to a flatter discharge curve, they maintain higher voltage through the entire cycle, avoiding the performance drop-offs seen in traditional LiPo packs.

With a 7.4V nominal voltage, 140C discharge rating, exceptional power-to-weight ratio, and a wide selection of configurations, MACH-1 RACING batteries are designed for racers who demand maximum performance, reliability, and speed.
