Introducing the new HCL-HP series designed to give your RC truck , car or boat high performance and reliability. Based off our popular DV Extreme series with an update in materials to increase the mAh to size ratio. Built with 100% LCO cathodes for optimum performance and cycle life. The low IR(internal resistance) of the cells used in these packs means you wil get very good acceleration and speed while keeping the pack down in temperature. These are a great budget oriented speed run pack. You will not find a pack with better performance at a better price. For those who are higher up in speed the SRD-V2 packs are what we recommend.
