4s lipo is used in the extreme class in dragracing which only last 1.3 seconds with the 7700kv motor. I have ran 4s1p A123 with the 7700kv motor and heated the batteries pretty good. 3s2p is doable, but be aware of your gearing with that motor. It's best to add a cap to the esc when running high kv motors.
