I'm seeing a problem that may be related. We have now fried 3 BeagleBone Blues Rev A2. We started using ours with a 15V 2.6A supply *without* connecting a LiPo battery. After only a couple of power cycles, the battery charging IC gets very hot and pops with a puff of smoke and a burned trace on the board. I've not seen any similar/related posts. Are the posted docs incomplete or incorrect? Is 12V the max? Is it required to have a LiPo battery attached at all times when powered?
