An outrunner may spool up slower as compared to an inrunner (more moment of inertia), but this would be no-load. An outrunner has 7 times the commutation cycles per revolution as compared to a 2 pole inrunner, so the ESC can synch it just as fast as an inrunner hooked to a pinion/ spur geardown.

Has there been any consistency with how the cells die? In a certain spot in the pack maybe? Have you tried slow charging or discharging of the packs to break them in? I have been running a123 a long time and only had once cell out of 50 die.
