Hello, I recently bought a 400ah Winston cell lithium battery bank for my van from a seller who also professionally configured the BMS for me cause I’m no expert. Things were good at the start, even though the battery only came 58% charged. It didn’t cut off charging from solar. P.S the seller balanced all the cells for me before I picked the battery up. I will double check all the connections are solid.
My problem lately is that I installed a 40a dc to dc charger and my BMS keeps killing the charging (from 40amp dc to dc charger plus little solar) because of single cell overvoltage (seems to be cell #1 of 4 every time). Even when the battery is only 50-60% charged but reads slightly over 14volts, cell balancing doesn’t seem to help much. When there’s 2amps of solar coming in after it balances the one cell it shuts off again a few moments later due to cell overvoltage. And every time it kills charging it displays 100% charged… I’ll post my settings and would greatly appreciate any help or advice.
I want to be able to charge my battery to 100% but have not been able to yet (after having it installed for a month). Thank you in advance for your time and assistance!
