The Mach-1 Racing 2S 140C HV 6300mAh Shorty LiPo Battery is a great battery option for anyone looking for a lightweight, shorty style battery. Weighing only 211 grams (+/- 1%), the HV 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 1:10 2WD and 4WD stock or modified as well as 1:8 Electric racers that want to run a saddle pack configuration and enjoy 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.
 
Mach-1 Racing 140C LiPo-HiV packs deliver the power needed by serious racers. These 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 batteries are lighter, providing a higher capacity per gram ratio. With 7.6V nominal voltage, 140C discharge ratings, incredibly high charge rates and ten different models to choose from, Mach-1 packs are perfect for racers that demand the absolute best.
