      Different battery chemistries do not behave identically in terms of failure modes, EMC emissions and interference response, and tons of other things. Just swapping one battery for another has a huge effect even before you consider auxiliary components like charging circuitry.

      My assumptions as to why you can just drop in an aftermarket battery and crate motor into an existing ICE vehicle (also, far from any vehicle, it is a relatively niche product) are that A. The batteries are way smaller and aren’t structural to the frame the way they are in BEV-first designs (but this is how we get good range out of them). B. The companies selling these probably aren’t held to the same emissions standards that an automaker is.

      Again, these are assumptions, I don’t work in conversions but in BEV designs primarily. I know there’s a ton of red tape for us to even think about changing battery chemistry, and we 100% would have to get all new certifications for it.

          12V sealed lead-acid batteries are a standard size and chemistry… They are absolutely not comparable to a BEV battery. The lithium ion 12V batteries are built to the emissions standards and regulations of the 12V lead acid, that’s a known quantity and a hell of a lot less energy. BEV batteries contain kwH of energy, they are significantly larger, are a nonstandard size on every single vehicle. Even if Toyota made it the same size and shape, the energy density might be enough to fail EMC regulations (without having to change the size and shape)

          I don’t know what else to tell you man, I work on electric vehicles for my job. Literally an engineer. You can choose to not believe me but it just isn’t anywhere near as simple as you’re acting like it is. Just because you think it’s like swapping an alkaline AA for a NiZn AA doesn’t make it true.
