feel the balance 3.65
sorry man your cells are not bad i had the same issue also some where 125mv difference ( heltech active balancer )Thx. Yes I have an active balancer - this Haltec one - but was to lazy to crimp and connect yet. I know I should do.
My second battery order was not as good as the first ones. I have 2 cells that are bad. Cell 9 always goes down first on discharge quite early.
I already have seen it on the Seplos monitoring tool, but after the CAN connection with Growatt I got all these datas.
Before I used a DALY BMS and had to use the Growatt in lead battery mode. Worked also - but now it is realy great.
solution is charge battery with connected balancer to 55.8v let it balance until delta = 0.020v this is good
now charge with low amps e.g. (3 amp) until you hit 56.8 v let he balancers do there thing until delta = 0.020v
now REMOVE balancer cable (the white cable helltech) set you selepsos balancer to start balancing at 3.48v
off you go
nobody is interested in delta voltage between de voltage of 3.1v cell and 3.45v cell
ps please post the firmware update to this forum
