Seriously, and not trying to be flip; the A123 cells work nicely at about 100 watts out per cell, others don't. Of course A123s work well at less current or more, but the sweet spot for the 2300mAh cells is about 35 amps, which yields just shy of 100 watts out per cell. The K2 Energy cells fall short on providing the power and do have a higher internal resistance than those produced by A123. There are a lot of LiFe-Poly packs that seem to be aimed at receiver and transmitter power. I have no firsthand experience with them, so really can't comment.
