Proffieboard V3 USB charging quick question

Using a standard kill switch setup between battery positive and the Proffieboard. I’m assuming the switch should in the on position, connecting the battery to the board to use USB charging?

What would happen if you plugged into the USB with the kill switch still engaged?

The charger just ends up powering the board if you plug it in without the battery connected.

Awesome, that’s what I was thinking, but I just wanted to double check. Thank you.
