ProTek RC 2 Cell LiPo Battery: 7.6V High-Voltage Performance

The ProTek R/C 2S 130C Graphene + HV 7400mAh LiPo Battery is the perfect battery option for anyone looking for a lightweight and high capacity LiPo battery. Weighing only 324 grams, this 2S pack is lighter than a standard 2S pack, with much higher capacity. These advancements lead to increase in both voltage and punch throughout a run.

This battery has been designed to improve 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.


  • Lighter than a hardcase 2S LiPo pack of equal capacity
  • More runtime, with a dramatic increase in voltage and punch
  • Silicone Graphene can handle more abuse and deliver more current than a standard LiPo battery
  • Improved efficiency, lower operating temperatures, and lower internal resistance!
  • Perfect for stock class racers looking to shave grams
  • 10C max charge rates - 1C charge rate recommended for longest life


  • DO NOT leave a battery in your model when charging
  • DO NOT leave lithium batteries unattended when charging
  • ALWAYS balance charge lithium battery
  • ALWAYS use a LiPo Safe charging bag/box
  • YOU MUST use a Li-Poly specific charger to charge lithium batteries (NiMH or NiCD only chargers WILL NOT WORK!)
  • YOU MUST not over discharge lithium battery packs
  • READ & UNDERSTAND the instructions carefully before operating this battery

NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in overheated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for the first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell). Do not use a battery that has too low a voltage. Do not expose batteries to sunshine or store/charge batteries at temperatures above 35°C or in a closed car. The high-temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging, or racing, do not charge it until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.

ProTek RC 2S 130C Low IR Si-Graphene + HV LiPo Battery (7.6V/7400mAh)
Functionally the battery works fine, but it just doesn't have the punch from some other brands I'm currently running. I'm planning to use this ProTek pack for practice now and reserve my other packs for races. A little disappointed concerning the price is the same or more than the packs I already had.

Great pack as always. Great pack for the AE SR10, RB10 and DR10. You cant go wrong with a ProTek Pack.
