You're close to totally correct., with one exception that was what led to my "edge of settings" comment. The inverter low cutout voltage maximum setting is 48 volts, and I wanted to set it higher. From the charts I've found, 48 volts on a 16 cell LFP battery is about 10% charge. Your making me think about this harder is leading me to believe it's a non-issue. On the inverter I can't set it to cut out until the batt is at 10%, but the BMS cuts it off at 20%, so it looks like my stress over this is all for nothing. The low batt cut in maximum is 52, which strikes me as not a problem.
