You know,... yesterday I visited a hobby shop and probed about lipo's in my plane with a regulator, after reading all the specs on all of them, you can't use a 3 cell on any of them, only 2 cell, I shy'd away, due to the fact that I only own 3 cell 2200-3000 MAH lipos. So even that fancy spectrum fan cooled 10 amp regulator, which wasn't the most exspensive, couldn't handle 3 cell lipos, and didn't seem to give me confidence in the fact that it shuts down if voltage hits 6 volts.
