So question for you, I have the maker hawk 3000 mAh battery and I can’t get them to charge and in fact, I just unplugged the usb and rebooted it, and at first it had an empty battery emblem but just switched to a plug… is there a driver required for batteries? 

 My experience so far is that the battery percentage indicator is not all that accurate. 

I've had a low battery appear to not be charging but after rebooting the board, battery actually had been charging just not showing the charge increase on the screen.
