You might consider Saft nicads.  They'll yield 2500-3500 cycles at 80% 
DOD (sorry, I have no specs for lower DOD).  They have high initial cost, 
but low life-cycle cost.  I calculated the per-mile cost for my Force at 
4 cents per mile, but yours would be higher since your car uses more 
energy per mile.

They also have better specific energy -- a 156v 100ah (at 1-hr rate) pack 
will weigh in at about 720 lb.  Cost will be about $8,800 plus shipping.
