Powering Cube Servo Rail from ESC's BEC

Cube Autopilot
1

Hey,

I have a cube orange, as i read i saw cube doesnt power the servo rail I need to externally power it. My question is I was looking at esc’s (I have pdb so 4in1 is not an option) some of them has 5V BEC. I am building a quadcopter so should I connect 4 of the 5V BEC From the escs to servo rail or only one of them?

Thanks in advance

If connecting ESCs to the Main and Aux outputs you should disconnect all but one of their BEC +5v wires. It used to happen that some of the voltage regulators would fight with each other and overheat.
Some times having +5v there on the outputs is handy to power some accessory or small servo, but there’s no requirement from the flight controller to have any power there.
