It sounds like dway was simply commenting on the realtively low Ah rating of the A123 cells simply for runtime considerations, not total current output.

Either 4s A123 (13.2v nom) or 3s lipo will put the 8L in a decent rpm range, but the 4s A123 will be closer to 40k rpm and might show some high rpm heat depending on how long the motor is run at that speed.
