Hello,
I am having trouble with pixhawk 6c, because it does not show nothing about the battery attached to the drone. The drone is the PX4 Vision Autonomy Development Kit with a 4S battery. Problem:
I believe it might be because the Pixhawk is powered from your USB connection. Normally it shows ok in battery status when it gets power from USB. Try to connect to the drone using telemetry and see what the battery level is
There are two power ports, default is the power1. If you use that port you should see the battery data. If you want to use other port, then you should configure it on parameters I think.
Good luck
