Ex got M3 in the divorce, waiting for EU Model Y!
Completely unreasonable assumption. They have publicly stated a few times recently that their pack costs are about $200 per kWh. Also that would mean that there is zero margin on their powerpacks which sell for $250 per kWh (please don't anyone post the foolishness that they are selling powerpacks for zero profit)!
It might not be accurate to use either of those figures ($200 or $250) for powerwall costs because it normally costs more to produce and sell a smaller product.
He just stated they sell for $470/kWh! (94000/200)
