Need a bms for 52v. Luna bottle battery i bought several years ago. 11.5 ah pf cells.
accidentally plugged it into a charged battery and 7 amp charge rate. Now a steady 56 volt at charge port but discharge flu ctuates off and on. 56v to 0 and back.
Another unrelated event happened at same time.
Solder failed in xt 90. So all fixed. No need for bms. Will be more careful in future. I was getting 7 amp charging with unequal batteries. Going to get some colored tape to color code.
