Absima Rookie Speed the perfect LiPo battery for all models with brushed drive. Safety First. Absima LiPo batteries have an extremely high quality standard and therefore offer perfect safety. RC cars with a brushed motor/controller combination cannot handle LiPo batteries with a C-rate that is too high. The motor and connections become too hot and this can result in damage to the motor or controller. This Absima LiPo battery is the perfect choice for RC cars with brushed motors. The optimum C-rate and low weight ensure maximum driving fun! Thanks to the rounded housing, these batteries are also specially designed for Tamiya models (among others).
