If I have only the 2.5A battery pack connected to my Raspberry Pi 2, it doesn’t power the motors or sensors on the BrickPi. If I have only the external battery pack (8x AA batteries) connected to the BrickPi, I noticed that does power on the Pi, but I don’t want to run the batteries down while I’m developing.
Is it safe to have the external battery pack connected to the BrickPi at the same time as I have the 2.5A external power supply connected to the Pi?
I figure it probably is (otherwise, how would I develop for this without always running down the batteries?), but I wanted to make sure so that I don’t fry this tiny thing!
