A123 packs are recommended because of their low resistance (not so much their ability to put out power, but rather their ability to absorb it). They allow power to be "put back" into them very quickly(ie:they can be charged in about 10 minutes or so with the A123 charger). This ability to absorb the energy back is what makes them "Castle Approved". The energy doesn't "get caught" in the ESC because the path to the batteries offers low resistance.

Hmmmm...... I know I saw on another brushless esc manufactures website that a123 cells have a comparatively high internal resistance. They did not want a123 cells being used with their esc's. I'll try and find a link.

Found it. This pdf applies to this thread. Page three is where they talk about the a123 cells. http://mgm-compro.com/pdf/en-motor-braking-050409-g.pdf
