What is the Receiver BATT Port??
In this video I will discuss the BATT port of radio control (RC) receivers and what that is used for. In short I will answer What is the receiver BATT port. Let's get to it!
In the days before electric powered RC model aircraft, radio control planes used gas powered engines. Most of these engines had a throttle control. A dedicated throttle servo was used to push and pull the engine throttle control, and this throttle servo was use to control power.
There was no lipo battery for an electric engine. Thus, these radio control sets needed an inflight battery, usually a nicad, to power the airborne receiver and servos.
Today, through the engineering magic of the Electronic Speed Control (ESC) and the BEC (battery eliminator circuit) our electric motor lipo batteries can be used to power both the motor (at the higher voltages needed) and the ESC can "step down" the lipo voltage for the 5.0 volts needed for the receiver and servos. Thus, the BATT port on a receiver is not used with electric powered RC model aircraft.
