Right, a full-timer wants lots of those cycles he paid for, so he might get a 500AH bank and use a 100 amp charger (if no solar adding to that) and get more cycles using the 0.2C rate and not so deep a DOD
Weekend warrior could plan to use 0-100s with a smaller bank in AH, since he knows he will never use so many cycles, but he needs to equip for the needed C rate (minus 10 amps very time the furnace comes on during the recharge, adding to gen time, same as with FLAs)
Lots of things to figure, but IMO it would be good to have some camping off-grid time to know what you want your LFPs to do. Then do the math and build your system. It is the same with FLAs but the cost of getting your math wrong is not nearly so severe.
