A123 systems is now selling 12v lead acid replacement packs!
I have been a long time lurker and have building battery packs for a while now. I though it maybe of interest to some of you to know that you can now get 12v LIp04 lead acid replacements for scooters direct from them. I know for us pack builders this is a bit expensive but for someone that doesnt want to mess with building battery packs this is a great solution at about 50% of the weight of the original battery.

How do you plan on selling these batteries at such a high price? It seems that your company continually passes up larger markets in favor of smaller, non-profitable ones. I read fully the specifications and understand what they replace, but the valuation of the batteries is waaaaaay off. Even at half the price they'd be too expensive for what they are. I can go buy CALB or GBS cells for a small fraction of the price and, at low discharge/charge rates, can expect similar life cycle performance. I calculated what it would cost for an a123 traction pack in my converted electric motorcycle and the cost would be about $10,000 to get the same performance I get now out of a $2,000 CALB 40Ah pack. Even the crappy Hobbyking LiFePO4 RC cells would be a better buy than those insanely and unjustifiably expensive a123 cells. Hell, lead acid are even a better deal for UPS and other non-traction applications.
I agree. The price seems a bit off.
I can get a 18Ah 12V AGM battery at that price.
