LiPo and LiFe cut off voltage

What is the lowest cut off voltage for LiPo and LiFE? I heard they are the same at 3volt per cell is it?

Lipo cutoff is 3 volts per cell and LiFe is supposedly 2.2 volts per cell. (according to Dave @ Zipp racing) He sells life packs so he should know. They only hold 6.6 volts so that would stand to reason that the cutoff would be lower than Lipo.

7.4V fully charged 6.6V nominal.

2.4v lowest for life cutoff

3.0v lowest for lipo cutoff

but these figures all depend on the battery and its design and manufacture.
