I am just a sailboat, but went LFP last Dec when I 2.5 year expensive FireFly batteries went bad. I have 4 x 100ah $300/ea drop in withy BMS Power queen batties I got off Amazon for $1319 total including shipping and tax. They have been working great on a full time cruiser currently in Bahamas and have never had shore power. I made no physical changes to my electrical and just reprogramed the alternator regulator and solar controlled.
Best thing about them is they accept all the current I can throw at them till they get almost fully charged and the biggie for a full time cruiser, don't have to fully that if I don't fully charge them each day that it is damaging.
Who knows if they live up to the hype, but if they make it 5 years I will consider it great.
