Can the ESC on this AIO board support really 4S battery?

Yes. But please pay attention to the motors. Here are two situations that the motor will burn itself and then the ESC frequently.

Situation 1: The motor's KV value is too high and could not stand the 4S power. For example, the BETAFPV 1105 6000KV motors could not stand the 4S power in aggressive flying. So we are working on a lower KV 1105 motor that could use with 4S battery. It will be released soon.

Situation 2: A poor quality motor will result in a 4S power.

Important: For the moment, no 0x0x/1102/1103 motors can stand 4S power that we know of. Please make sure your motors could support the 4S battery before using.
