In 2p config you could expect even more from A123 cells. I see Amp peaks of 100-120A used as 10s1p (My eagletree v1 is rated for max 100A). So if your ESC and Motor is able to provide/suck 200-240A, your battery pack would provide it for short bursts. At 100A as 1p config voltage could drop to 2V (i see a range from 2 to 2.4V). It really depends on cell temperature and cable length.

From a Power point of view i calculate with a max of 250Watt per A123 cell (110A@2.25V). So 3s2p are able to provide up to 1500 Watt (and maybe a little bit more when you warm them up before driving). There is also a feelable difference in power when they come fresh from the charger as when you drive them say 1 day after you charged them.
