That battery pencil is way
That battery pencil is way wrong. TESLA has batteries that now cost $80 per KW. That comes out to $40,000 for the battery pack. Also a new battery starts shipping this December that will cut 15 to 30 % off the cost.
I also wonder what that new 30% commercial tax credit (up to $40,000) will do to demand. Also you would not believe the net cost after credit for a CA company.
