This was just touched on in another thread here very briefly. I've wondered the same myself and every time I show people the motor and bay they always think it's an odd thing to have in an otherwise revolutionary package.
A quick google search found this result and lots of others that basically link back to it: http://www.plugincars.com/why-do-el...lt-batteries-when-lithium-lighter-129118.html
Is it just cost? Is it regulatory in some way (old school rules that don't cater for new-school all-in-one battery tech), or what is going on here?!
It's really two questions. a) Why do EVs have two batteries, not one? b) Why is that battery lead-acid?
Thoughts, facts, conspiracy theories all welcome, especially if someone has some cold hard facts or insider info?
