I have twenty five years experience in electronics and believe me, there IS a charging regulator on the board. If you charged a battery straight from the USB port you VERY lucky that it did not catch fire or actually explode.
I STRONLGY advise anyone-
DO NOT try to charge any battery from an unregulated source unless is is specifically made to do so, which these batteries are not. The results COULD be catastrophic.
