None of them will last beyond 20 years before they start going bad and there’s nothing you can do about it.
there's a useful life for ev service, and there's a useful life after ev service. seeing these arrays being recycled for power storage is the way.
that said: good luck getting all the complex shit in an ICE car to last 20 fuckin years lol. something is gonna give. EVs seem complex, but it's far simpler than the array of shit needed to make gas blammo work as motive force for transport.
