Would be interesting to know whats going on in the industry with LFP. Pre-built lead acid replacement LFP battery prices have been dropping almost daily and are down to high end AGM prices [1] and quality has been going up [2], these batteries were twice the price a year ago.
Will be replacing the lead acid in my RV soon with LFP's, it really a no brainer.

It's actually pretty amazing to watch how quickly LiFePO4 batteries are dropping in price over the last few years and how much better they are getting. You can get a 12v 100ah drop in replacement for about the same cost as a high lead acid AGM [1], and there are some really interesting rack mount 48v's at very low price per Wh [2].
These lithium iron batteries are more stable, have extremely long life and avoid cobalt and nickel while having only slightly less energy density. Pretty sure they poised to replace lead acid in almost all applications over the next few years.
Tesla is finally replacing the lead acid 12v battery with a lithium 12v and of course they a going LifePO4 for the main pack in some lower end models.
I just replaced my worn out high end AGM's in my RV with LiFePO4's, 3 times the price but 4 times the usable capacity in only slightly more space and much less voltage sag throughout the discharge cycle and much faster recharge acceptance and at least 6 times the cycle life, should be the last batteries I need to buy for it.
