I am looking for a 3.7V LiPo battery circuit that will handle over-voltage protection along with charging and 3.7V to 5V boost. I've found this popular pcb on ebay:
It seems to cover all that I need but I can't tell if it steps down the charging voltage or if I have to provide it with a regulated 3.7V supply to charge the battery with? I can tell that one IC is an 8205A which provides all the over/under protection features but I can't read the numbers on the other ICs to look up data sheets. Is there a sure way to tell if this pcb has this feature or not?
