The only thing I am worried about with the new A123 cells is energy density and cost. Energy density is capacity per weight. The A123 cells are very capable of high discharge rates, like 100C peaks, 50C bursts, and 30C continuous (I think). IMO, that is completely unnecessary unless you are doing a speed run where weight is a major issue. If they were to produce a cell with better energy density and a discharge rate of 15-20C continuous, then it would be a much better cell.
