Hi all,
I built a 120Ah battery using the Overkill Solar BMS (also sold in many flavors from Alibaba) and installed in my camper van. Once the battery is at 100% and the van still running (alternator charging) the "cell over voltage" protection from the BMS frequently kicks in and stops charging. The over voltage protection is set to 3.65 per cell. Is this normal and simply how the BMS controls charging or is something wrong?
Separate question, I expected that charging would slow as the battery approached full, but this does not seem to be the case for me. I am charging at 300-400 watts while the van is running right up until the battery is full.
Thanks for the feedback and help.
