If additional current is needed, consider using a spare XT30 split off from  the main battery to power the microcontroller and disconnect the 5V (red) cable from the BEC.

30 +Two dual channel Sabertooth motor controllers are needed because each motor is connected to its own channel and can be controlled independently. Normally the encoders are connected to the microcontroller to measure angular speed and estimate distance traveled. Connections between microcontroller and the Sabertooth controller and encoders depend on the microcontroller chosen.
