ooops! i've been doing numbers on the split bank for a week now, and was thinking in those terms. lol.
??? but is my premise still sound? at say 80% efficiency, one hour at 40 amps should replace at least 32Ah, yes? plus 3 hours of 40-10 amps should more than replace the other 11Ah's, no?
??? i don't understand how the batts can take so many amps for so long. i do realize the higher voltages accommodate higher currents, and that the tri-metric is basically saying what i told it to say, but all this was before the tri-metric install, and the peak was just replacing what i used, by bringing the batts back up from 12.6v to 12.78v (where they always seem to level out after the surface charge burns off). what is it i'm missing? there is obviously a difference between charge current amps and Ah's, (especially) well into the charge cycle.
...same goes for equalizing. 3 hours at 15.5v and 20 amps tapering is a lot more than the few Ah's that get replaced.
