Castle CC BEC Pro 20A Switching Regulator In electric vehicles, Battery Eliminator Circuits (BEC's) are small devices that eliminate the need for a battery pack to power a receiver and servos. They draw higher voltage from the motor batteries and drop it to a voltage level that is suitable for your receiver and servos. This is required in applications which draw high power for multiple servos or use more than 3S motor packs, as most ESCs with linear BECs are not designed for these applications.

NOTE: CC BEC Pro should never be operated in series or parallel with another BEC or backup receiver pack connected to the RX/Servo side of the circuit.
