1 year ago Hi, I looked it up based on the marking on a different BMS and I would say it's this one: https://www.mouser.com/datasheet/2/916/PSMN025_80YL-2938901.pdf but can't say 100%
Do you happen to know any information about the Q13 MOSFET just to the left of the ES9 connector on the BMS? Mine seems to have blown and taken a chunk out from the source pins area but I can't find much information about it. It's hard to trace the source pin since much of the board around them is now carbon. The part looks to be out of stock everywhere except Alibaba but before I can replace it I need to find a alternate place to connect the source pins. The gate and drain seem to be in good enough condition for a replacement I think. Any information about the function of the MOSFET or where on the board the pins go to would be much appreciated.
