How many DeWalt packs would you need for a longer-range EV rather than a racer?

----- Original Message ----
So no one has heard of anybody (yet) buying 40 A123
(Dewalt) 36v packs for $5000 (yikes!) and running an
EV off of them....? (assuming 72v at about 50Ah for
around 1/2 hour of 100amp usage)

Not to mention that you'd be charging each from its base station. There is
not much control to the charging of these batts... so you'd also want to
check each for charge levels.

Then again, that's not uncommon for any of this sort of batt. Despite all
the hype, I'm not sure any of these are ready for prime-time pushing a full
sized EV down the road.
