When connected with motor, it is capable of supplying up to 320 Amps (forward) or 160Amps (backward) of continuous motor current. Its integrated Battery Eliminator Circuit (BEC) powers the receiver from the motor battery, with automatic cutoff of the motor power to preserve receiver power as the battery becomes depleted. It is small and powerful, which can be used for different type of ship or car.
