I'm starting to wonder if the "745 mile" claim is actually admission of technical failure. Think about it. If their battery really does have that capacity and can "charge in 10 minutes" then why not a battery half or even a quarter the capacity?
Perhaps this battery's maximum rate of discharge is so low that such a massively oversized pack is needed to get sufficient momentary power to the electric motors?
