Hello everyone !
Today I had my very first big issue with my LiFePO4 battery pack, to be precise, I am unable to top balance it.
First of all I connected my 8 x 52Ah LiFePo4 cells in parallel and started to top balance them with a common drone battery charger, with a normal setting of 3.65V per cell charge.
Without days and no real success they were stuck at 3.36V per Cell, and since the charger is inappropriate to top balance I chose another method, to put them in series with the BMS to charge to almost full and then switch back to parallel to finish the top balance.
The issue is that, since I do not have a bench power supply, I am feeding current via 2 x 24V 150W Led driver boards ( in series so 48V, 6.8A and 150W total) through a Solar charge controller which works as a charger. The latter is then connected to the Daly 80A BMS.
The problem is that the BMS, I suppose, cuts the charging process because receives too much current in a very short time, could this be ?
I will attach all my BMS settings in order to show you my situation.
Hope this could be solved, thank you everyone !
