a 62 kWh battery pack (such as that in a tesla 3) would theoretically come out to $8,600 using this figure

right in the equivalent ballpark range of putting in a new ICE motor

hopefully costs of reman/refurb battery packs will become even cheaper than $139/kWh

Needs to go even lower.

We need more innovation, supply chain optimization, more mass manufacturing scale, and more of the battery chemistries with cheaper raw materials.
