"If you want to measure your battery capacity, charge your battery full, turn on a load (the current doesn't really matter) and then run until the BMS cuts off. Look at your battery monitor to see how many Ah came out, and that is your capacity"
That makes sense, kind of like my "new plan". It would not quite work with my Trimetric of course, since it gets its 12v from the battery being monitored. When the BMS cuts off the battery, the Trimetric display would go black. Have to take the AH reading just before the BMS shut things down. Have to know when that is about to happen.
time2roll is going to try to camp the same as now using his voltmeter as the only monitor he needs.
I like Itinerant1's approach. He must have done a whole bunch of math before getting his set-up. His 500AH bank was not chosen at random, nor his amount of solar. He figured his daily AH usage and the various rates. He is thus able to do it all, staying above the lower knee, and get his cycles worth of LFP without having to use high rates. He monitors it all like crazy to make sure it is working like it is supposed to. He "adjusts" his solar so it can keep up by moving North and South as required as well as keeping in comfortable climates. None of that happened by trial and error--he did some math first.
time2roll has the luxury of being able to do some trial and error, not being a full-timer. He can get a monitor later if needed.
Anyway, you LFP guys can figure out how to play it each to his own.
