Battery and USB at the same time

Hello folks,
I have a little hard time with the battery calibration on the PX4.
Actually I use a USB cable as power and communication for the board, now I am trying to do an HITL simulation but without the battery is not possible to do it.
Can I connect the USB and the battery at the same time, or my PIX4 will die? :boom:

Hi, I burned out my pixhawk 4 once because of a numerous connections with battery and USB simultaneously, however, if you are just testing for a short amount of time, there shouldn’t be any issue
