The trouble with AC systems is that since they tend to be higher voltages, you need LOTS of little batteries.
My friend's AC Dodge Neon is around 300V, with 27 or so 12V batteries in it.
I think that the Solectria Force was one of the most popular AC cars. That used a 156V AC system of 13 group27 size gel batteries.
Very exciting news about the car and the motor!
