OK and still in all practical use the LFP is so much better than the dinosaur FLA.
FLA has no advantage except on initial price for small capacity applications.
Initial price is made up for with higher energy density, more usable energy storage due to true deep discharging capability and long battery life. Also prices are dropping fast and DIY packs are pretty easy and fun to make.
One downside to LFP is cold weather charging, but this can be mitigated with an insulated box and a small heater.
Some people may get a little religious about battery chemistries but the main selling points for me are lower weight, higher energy density, longer life and high charge and discharge rates. When something comes along that outperforms LFP on any of those attributes, I'll be preparing to move to the new chemistry.
Edit: For example, I went from 100ah of FLA(50 ah usable) to 200ah of AGM(100 ah usable) to 271 ah LFP(216 usable). Plus I saved enough space going from AGM to LFP that I was able to add an inverter and can now run the microwave without using the generator.
