I could run the numbers through a spread sheet for you if you want. I would need to know Cd, Frontal Area, vehicle weight, estimate of rolling resistance of your tires (if you don't know I will just throw a reasonable number there), electric motor efficiency (usually around 90%).
My numbers though will assume no drag from the cars normal engine hookup.
If you want me to run the numbers for the batteries you got I can do that as well.

Working backwards, could you run that spread sheet to tell me the capacity required for my battery pack using the following criteria?
reasonable accell stop & go: 0 - 35mph in 15s
top speed: 35 - 45mph
range: 15 - 20mi
Cd: 0.450
Frontal Area: 15 sq. ft. (2.5' x 6')
vehicle weight 5000lbs (4250+750)
rolling resistance tires ?-full size truck 265/70/17 AT
electric motor efficiency 90%
Thanks
