hello! need some help from the brain trust!
built a 100ahr lifepo w a jbd bms. using xiaoxiang bms v3.1 1026. thoroughly top balanced the cells to 3.65v. when i put it in use, i noticed that cell 3 was charging faster and discharging faster. meanwhile cell 1 wasnt fully charging. i think this was due to cell 3 hitting charge limits and disabling charging.
so i disassembled it and top balanced the battery again. then i swapped the position of cell 1 & 3. now, cell 1 is overcharging and cell 3 isnt getting to full charge. is this symptomatic of a bad bms? anyway to fix it? or should i just buy another?
TIA,
pc
