Hi, I think that I got a defective LiPoly backpack.
Without connecting the backpack to anything else, I plugged in a 3.7v 1200mAh battery. The thing shocked me, then got very hot. None of the lights turned on. You can see on the back of the backpack that the board got deformed from the heat right where it says "charge", "default", "jumper", and "5A"
I contacted the support email about getting a replacement. They told me to post here first.
