The 4 day slow discharge to 50% is going to be more detrimental than high recharge rates and high voltages. I'd be looking at ways to charge daily rather than the low and slow to 50% then wondering why they never seem to get near to 100%, even when the effort is applied. (END QUOTE)
this is exactly why i'm leaning toward a 215 a/h bank... the 430 a/h bank is just too big for my daily usage of 20 - 30a/h's. i can't possibly blow thru 30% of the larger bank in just 1 - 3 days, unless i'm running the a/c, fans, un-necessary lighting, etc.
50-80% on a 215a/h bank would be 64.5 a/h's... which matches my 3 days usage during the week, and 2 days use on w/e's... thus my proposed scenario. and even then, i'd only be charging every 2 - 3 days, not every day, as you suggest. moreover, the 430 a/h bank would drag out those charging times to every 4 - 6 days, and greatly increases charge duration of each cycle.
and even if i add a pump and fan for a hydronic heat system, i'm still only going to increase my daily usage to about 60 - 70 a/h's ... which would work well with a 430 a/h bank with charging every other day. so i could alternate cycling two banks (to keep their wear and tear the same) from late spring to early fall, and all 4 batts as one large bank during the colder weather.
