Is there any rules of thumb as to how much to lower the charge efficiency factor when your batteries start to show signs of aging/degradation? The BMV has been reading incorrectly when the SOC nears a full charge, and I heard we need to lower the efficiency factor to get it dialed back in.
If it's currently at 96%, do we want to just decrease it in increments of 10%? That would be starting at 86% and then moving from there. Any input people have from managing this setting on older batteries would be great.
