rektide is right to point at the need to over-build the pack: you need the car to be rigid without the batteries, essentially, and the battery to be sturdy on its own. You could argue that the car only goes through significant stress when the two are together, but every mechanical engineer is not liking that math. Another argument is what Sandy Monroe [0] think is the biggest one: moving connectors. It’s not just high-energy cables, but possibly coolant, etc. Those will be the first thing to fail. Sandy also mentions the risk of using someone else’s over-worn battery, but that’s more his atrabilar personality than something that could be engineered away: have the platform the battery regularly, even have the car do diagnostic and remove the worst ones from circulation.
