A123 Motorcycle Battery?

4s4p will be the best bet. You won't need much. Here is the tek battery page that does the same thing with an internal BMS http://www.tekbattery.com/Batteries/PricesDoc.html

4s is the replacement for 12v lead acid. It will get slightly undercharged by a lead acid charger too, which makes it last longer.

Thanks for posting that too! I am always looking for places that make packs from A123 cells... I like to keep the ideas, and compare them to how I would make mine. That is if and when I make an electric motorbike, and in the future, an ultra light super car.
