I can currently find exactly zero used cars with a LiFePo battery here. I looked around more and it doesn’t seem to be even used by any car brands that exist here so I have no way to check how expensive a replacement would be. I’m assuming there’s a reason it’s not used but I’m not going to dig into battery research over a lemmy post.
If those batteries solve all the issues leading to used EVs being feasible then that would be great in about a decade or two if they adobt that right now.
