I wonder how slate got the idea that they're not "expensive". Maybe the prices have been manipulated independently of supply.

Batteries are following the same price curve of solar panels, and are about to get stupid cheap. EDIT: If Tesla is able to drive down battery costs to below $100/kWh, I assure you, EVs won't be the biggest success story; you'll be able to turn every wind and solar generator into dispatchable generation cheaper than coal, nuclear, and natural gas. We'll be off fossil fuels in ~10-15 years.

  Nitpick: the unit you mean is kWh, not kW, which is a different, though related, unit of merit for batteries. (kWh measures capacity; kW measures output.)

  I think there's a bit of confusion about Pack prices vs Cell prices. The $145 is cell only, which is one of the reasons it is so much lower. There don't seem to be consistent pack-pack price comparisons.

    I agree there is a disparity between the Bolt's cell-only cost vs Tesla's cost all-in on a pack. Regardless, the cost is below $200/kWh, and it appears that the cost decreases will continue.
