The Price of Electric Car Batteries is Dropping Fast
My EV's Li-Ion batteries weigh in around 600lbs for 23kWh of capacity (about 19kWh of which is usable to ensure the battery lasts longer) for point of reference (Ford had initially said the battery costs $12,000 but that was four years ago--I'm sure its price has fallen now).
