I thought “This sounds a lot like the logical next step to what Damien Maguire has been working on” and sure enough it is!

This man has been working for years on repurposing old EV hardware and using it to electrify cars, sometimes in really wacky (and extremely entertaining) ways on the Youtube channel “evmbw” - I suggest giving it a watch! Some of the cars are really scrappy, but he obviously knows very well what he’s doing.
