    The battery in my car got replaced. For a 82kWh battery it was $11k, like two years ago. And it only keeps getting cheaper. And they come with 200.000 km warranty.

    LiFePo4 have like 5 times the lifespan. So they will outlive your car, you can put them in your next car, they will outlive that one too and then you can use them as buffer storage for your house.

      What car can you even do this? These days I expect the battery to be proprietary with DRM and discontinued by the time it makes sense to replace.

        Right now?

        The only ev I’ve seen powered by LiFePO4 was built by an enthusiast.

        … So the short answer is: you can only build one.

        LiFePO4 batteries are less energy dense than lithium/cobalt, which is what most use (notable example being every Tesla ever), but some use prismatic cells, IIRC. But Cobalt based cells are generally preferred for weight reduction.

        What we need is a battery with the endurance of LiFePO4 and power density that’s as good as, or better than lithium/cobalt cells. Right now that’s the Holy Grail for EVs, and research for such a battery is ongoing. There’s a few that are looking good, but still in fairly early stages of research.

        IMO, if that kind of battery can be developed, or another method to power EVs is proven to be effective and safe, then very quickly after that, ICE cars will stop being produced altogether.

      11k is more than double of what the average person pays for a car here. The vast majority buy used cars for about 5000 euros on average for a good quality one but you can get a car for even under 1k. Until EVs can hit those prices only a handful of people will buy them in poorer countries.

        They will, you can get a Zoe for 6k right now. There just are no 20 year old evs yet.

          The cheapest used Zoe I can find in Estonia is 7k and it’s in bad condition all the rest are from 15 - 25k.

              7 is less than 25 so I’m confused about what you’re confused by. Maybe prices haven’t gone down as much as you’d like, but they’ve gone down, so clearly they are second-hand vehicles.

                I was the one who said you can find them for 6, because I’m looking to buy one. Someone said they cost 15-25 used. Who buys a used car for the price of a new one?
