Hey
I built a 4s100p 270aH Lithium Ion Pack.
I installed a Daly 4s35A 12V BMS and wired it up.
It appeared to be working perfectly for about 6 weeks with daily use then the inverter kept randomly rebooting.
I checked out the pack and found this...
Top pack - near the positive - was 3.63V
Second pack was 4.2V
Third pack was 3.94V
Fourth pack was 3.99V
i have been charging my individual packs with my B6 charger on 1s to bring the voltages in line with each other and about to put it back together.
What's your thoughts about the BMS? Is it faulty? Could there be any other issue?
I did find a single cell which was hot and have removed that. Once it cooled down it's voltage was around 0.25v.
Could that affected the BMSs ability to keep the packs in balance?
Thanks in advance...
