Phosphates are, after all, spent by tonnes as a fertiliser. Is there a good source for LFP that actually is cheaper than plain lithium ion? I've been looking at doing an electric conversion, and it seems like they tend to run about $400-500 per kwh, whereas lithium ion tends to be more like $300-400. I can believe that LFP is cheaper to make, but if that were so, it seems like it ought to be reflected in retail prices unless vendors are selling them at a huge markup. (I've only looked into this recently, so I don't know if battery prices have spiked because of tariffs on China or something like that or this is just the normal retail price.)
