How big of an A123 cell would it take to start a car?

[DLS II]

To me what's very interesting is figuring out how many it would take to power a full size car. A compact car using 20 Trojan T105 6v batteries(series/parallel-120volts,128amphr) will go apprx. 60-90 miles on a charge.They would weigh over 1200 lbs. It would take 2400 A123 cells(2300mah) wired series/parallel to give you 138amp/hr @ 132 volts. The pack would weigh 450-500 lbs. The limiting factor is cost-you would have to be able to get the A123 cells @ $1 ea. or less and then find someone to help build the pack and the charge/management system. The trojans are $200 apiece. Don
