Are you saying you bought an electric car with functional 84kwh pack for less than 3 grand? If so I think the outlier is you. That is a better deal than I have seen.

Did I read incorrectly?

> which is around 3.8kwh, costs $2400 USD. To store 10kwh would cost $7200 USD (which gets us more than 10kwh).

84kwh / 3.8 kwh is about 22. 22 * 2400 is ~53k.
