Rather than having a shorter lifespan than internal combustion engines, EV batteries are lasting way longer than expected, surprising even the automakers themselves.
less about easy to start an EV company (honestly you can buy engines, so that’s not really the hard part; manufacturing is, as tesla found out the hard way) and more about it being easy to build an EV from almost nothing… you can ram batteries and electric motors into almost any body as you pointed out, so if a company makes junk it’s pretty easy to replace bits with whatever you like, and since electrons are electrons are electrons, your battery, motors, etc only have to kind of match
