a123's do not go by CC's. They are 3.7v per cell and lipos are 4.2V per cell.
It is a lot of work, but if you have a hyperion charger than it is very easy.
The batteries last longer than lipos of far greater maH due to the fact that you
can use 100% of the batteries power
Isn't that a lot of work? I see a DeWalt pack for 140 with 10 cells and the Tamiya 6 pack for 8500 Yen here (about $90) How is the discharge rate? A123 rates them 30c to 60c, but according to Bob Novak they haven't done any testing with them, I don't know about CC.
