Yeah, LFP is where it’s at as far as longevity and price and price per cycle and safety.

Lead acid are still more forgiving (although with the caveat that they don’t last long even if we’ll cared for), but LFP is pretty wonderful.

I'm on year 3 with some AGMs. I bought used group 24 AGM batteries from a local used/recycler battery joint that were used in large hospital battery backup applications - they're typically never cycled but once for testing and always kept topped off. Very common to find these kinds of batteries in bulk a few times a year where I'm at. The flooded batteries (mostly Interstate) that I used in years prior would last at most two years even when properly maintained. The FL heat just nukes those things.
