My local pick’n’pull sells Nissan leaf batteries for $300
First of all, how many can there be that are actually still in good shape, and with an EV there is a high likelihood that is why it’s there in the first place. I see them in a range of 2k to 4k based on condition.
Pretty sure $4000 is a bit steep for most folks to repair a car that far down the depreciation curve.
How many Tesla batteries have you run across?
