I've found this interesting description with some pictures of the board with the identification codes of the ICs. I dont know it this may be useful for you. http://www.myfixguide.com/manual/xiaomi-mi-power-bank-teardown-20000mah/ Title: Re: Battery protection IC Post by: Sideshow Bob on May 14, 2019, 07:06:55 07:06 ABLIC is quite large on Lithium-ion battery protection ICs. I will guess you find your part in the S-8261 Series
