Hi everyone,
I'm putting together a 16s 100Ah battery bank with an Overkill 16s BMS. This bank will power an electric ride-on lawnmower (basically doing an AGM to LiFePO4 conversion). I have a question about selecting a charger. I noticed that LiFePO chargers (such as this one, or this one) have a max charge voltage of typically 3.6V or 3.65V per cell. However, reading through some posts I've seen general recommendations to not charge LiFePO batteries routinely to 100% if not needed, but rather use ideally 80% of the range. Since I can't lower the max charge voltage in these chargers, is it common practice to just let the BMS cutoff the voltage by means of setting the overvoltage protection at a desired max voltage? If not, how should I be controlling the top charge level?
Thanks!
