My bms had water damage and has been fixed. A few M2t mosfets, a few rb capacitors and one of the two big 80v mosfets were changed for new ones.

The board lit up and was able to ride it. Alas it died on me at 50% and never was able to recharge or balance it. Charger goes red, charges up to 50% then stays green.

Upon installing a owie I saw what I thought initially that the cells are out of balance (group 8 showed low reading).

I manually checked the cells inside the pack and their reading was perfectly balanced. I also tested another battery, same wrong reading on group 8: https://ibb.co/zGqBvJn

Im sure it's something on the bms still.. But cannot figure out what.

Any ideas please?

@lia I've been there before 😅 pulled out a capacitor when removing the xt and it did show above normal readings. Figured it out quickly as c11 was missing and I fixed it by replacing. But that was another bms from another board.

I made sure to even check them one by one with a multimeter and they all give me readings.
