Hello, looking for help with my 4s lishen 280ah battery pack with daly smart bms. Sometimes, but not always, when I'm charging the battery at 20ah I notice the charging gets into a loop of ramping up the amperage then disconnecting. It appears the "cell voltage difference disconnect" is triggering as I see the difference ramping up to 0.271v before disconnecting.
I did top balance the cells and I have an active balancer installed as well. It just appears one cell is taking up the voltage quicker than the others. is this normal ? Bad luck? or damaged cell? what are my options?
thanks!
