The ProTek RC 2S 130C Si-Graphene + HV Shorty LiPo Battery is built for racers who demand maximum voltage stability, punch, and consistency from start to finish. Using advanced Silicon Graphene High-Voltage (LiHV) cell technology, this pack delivers higher efficiency, lower internal resistance, and longer cycle life compared to conventional LiPo and LiHV batteries.
At just 219 grams, this shorty pack is lighter than many standard shorty batteries while offering a massive 6400mAh capacity and 7.6V nominal voltage. The result is stronger acceleration, improved runtime, and a flatter discharge curve that maintains voltage deeper into the run—exactly what competitive racers need.
This battery is an excellent choice for 2WD and 4WD Modified, Stock Class racers looking to shave grams, and even 1/8 e-buggies running lightweight 2×2S saddle configurations. With improved thermal efficiency and durability, the ProTek Si-Graphene line is designed to perform under the most demanding race conditions.
