This is the CC BEC 10A Receiver Battery Eliminator by Castle Creations.

FEATURES: Eliminates the need for a receiver and servo battery pack
          Draws higher voltage from the motor batteries and drops it to a
            voltage level suitable for the receiver and servos

INCLUDES: One CC BEC receiver battery eliminator

REQUIRES: Installation in the aircraft
