The ProTek R/C 4S 130C Graphene + HV 5600mAh LiPo Battery is a great battery option for anyone looking for a high capacity, high output 4S battery. Weighing 454 grams, the 4S HV is lighter than a standard 4S pack, with much higher capacity. This provides more runtime, and a dramatic increase in voltage and punch over the course of a run. 

This battery is designed to have improved power to weight ratios while maintaining a low CG. The improved efficiency of this pack will allow for lower operating temperatures and lower internal resistance. This gives users a more consistent battery pack. ProTek Graphene + 130C Packs deliver the power needed by serious racers and enthusiasts alike.

Lab testing has shown that ProTek R/C Silicon Graphene packs have double the cycle life when charged at 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 Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 7.6V nominal voltage, 130C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C 130C Graphene + packs are perfect for racers and bashers that demand the absolute best.
