The MACH-1 RACING 2S 140C 4400mAh ULCG Shorty LiPo Battery is a great battery option for anyone looking for a lightweight, shorty style battery.
 
Weighing only 155 grams, the standard voltage shorty is lighter than a standard shorty pack, when compared to standard LiPo and LiHV, these cells deliver improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage.

This pack is ideal pack for 2WD or 4WD Off-Road 13.5 or modified racers that want optimum voltage for the entire run. The improved efficiency of this pack will allow for lower operating temperatures and lower internal resistance. This gives users a more consistent battery pack. This MACH-1 RACING ULCG 4400 MAH 140C lipo will deliver the power needed by serious racers.

MACH-1 RACING packs have double the cycle life when charged at .5C to 1C rates, and can be charged at higher amp rates, with less risk of damage to the pack. More importantly, the discharge curve is flatter, meaning the cells maintain higher voltage throughout the discharge cycle with no significant drop off. Additionally, when compared to conventional LiPo batteries MACH-1 RACING batteries are lighter, providing a higher capacity per gram ratio. With 7.4V nominal voltage, 140C discharge ratings, incredibly high charge rates and ten different models to choose from, MACH-1 RACING packs are perfect for racers that demand the absolute best.
