Using Silicon Graphene technology this battery packs a punch with it's 50c discharge rating! Designed to work with the Losi Mini T, B and Mini JRX2 this pack offers extended runtimes with it's larger 1100mah capacity. Equipped with an EC2 style connector makes this a plug in option with no need to mess with adapters or to get out the soldering iron. With more time on the track and the ability to dish out the power this Protek battery pack is an excellent upgrade for your Mini T, B or JRX2 vehicles. 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 7.4V nominal voltage, high discharge ratings, incredibly high charge rates and a variety of models to choose from, ProTek R/C Graphene packs are perfect for racers and bashers that demand the absolute best. Note: When purchasing this battery as an upgrade for the Losi Mini-B it is also required to buy a standard 2S LiPo capable charger.

Direct fit for Losi Mini B, T and JRX2 vehicles

More runtime, with a dramatic increase in punch

Silicone Graphene can handle more abuse and deliver more current than a standard LiPo battery
