Hi all. First adventure into battery building. I attempted to pre-charge my 8s 280ah pack, wired in series and connected to an Overkill Solar 8s BMS set to stop current when a cell hit 3.65. All cells but 3 were matched at the factory st 3.3. The other 3 were 3.4, 3.26 and 3.28.
After charging about 24 hrs, I woke this morning to see the power supply no longer charging and most cells at 3.35 or so. Seems maybe 1 cell hit 3.65 and shut off the power.
I went ahead and reconfigured the pack in parallel, removed the BMS, set my power supply to max current and 3.65v (see picture).
Should the power supply be showing low current like this?
Anything I could have done differently during the pre-charge?
Thx all.
