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.
and this is different from a normal battery how? the only difference is that if you find you use 60-80 AH a day and you want to go for 3 days on average with LFP you would buy say 300 AH of battery, if your looking at FLA you would have to buy 480 AH of capacity. if you have solar pannels that add 40AH a day back in then you can cut that in half but I wouldnt as you might need that extra capacity if you hit a few days of rain. the batteries dont power things up different,or magicly do other tricks, they will supply power with in there operational capacity. for a flooded battery will it supply more than 50% yes but thats when you start decreasing the life of the battery. you don't have to worry about this with the LFP as the 3000 cycles is based of 100% discharge if you go with more capacity than you need with them and keep the discharge shallow, well maybe you can pass thoes off to your grandkids when you pass.
