I got it from 'Mouser Electronics'.

Hmmm 15C charge, now I know for a personal fact that A123's can charge very fast, but stating that it can do it in 15C... BULLSHIT. They would have to have redesigned the whole chemistry for it to be able to do that safely.

I seen A123Systems do a 10C charge (6 mins) on the M1, but at these rates you need to up the charge voltage to actually get the amps they are talking about. Heck, for me to get a 15 min charge(10amps) on a 1p A123 pack, I need to use 3.9v/cell over the standard 3.6v/cell. No if we increase the rate to 10C, that should go up to pretty well 4v/cell, which I know is still safe with those cells, but will lower the cycle life alot. Now, at 15C charge.... well, you get the picture. I call BS, a big pile of burning $HIT.

Who even has the equipment to charge at those rates no doubt!? A standard 15 amp breaker will trip at 1500watts sustained, and thats AT THE WALL. You have to factor in efficiency of the AC/DC power supplies, then the charger, and then the heat created by the cell itself. Enough ranting for me.
