Recently hooked up solar, and it seems to be wanting to overcharge cell 1.
I caught it earlier at 4.2v luckily and quickly discharged it down to spec and had all 4 cells back within .03 The 3 other cells were fine and stayed grouped very well.
My DC-DC charger does'nt cause this issue as easily, but it has gotten a cell or 2 off before. So i went and hooked up the solar charger correctly, (vs just directly to the battery + and -) running the negative to the BMS so it can read the solar incoming and prevent another over charge like that at least.
But im wondering what causes 1 cell to overcharge like that.
I never top balanced them when i got them, so i think i'll do that as well. Hoping that's it.
Preciate any input.
