Ha! But I can replace a timing chain or repair a modern automatic transmission, for not much money. The cell replacement would in fact cost me much more money because I am NOT touching those voltages.
But also, that's exactly why I'm saying it's best to get an EV that's actually used, not one that's near-new. The depreciation hits hard for about 4-5 years, not one or two and by the time the model's been out for multiple years, there are donors to get cells from. They're much cheaper than new at 1-2 years, but they're DIRT cheap 5 more years after that.
