I should have added the other part of the Q&A, for completeness:

Q: hi whats the diference between limn204 and lifepo4 thanx 01-Sep-07
A: In Generally , LiFePO4 is better but more expansive than LiMn2O4. LiFePo4 cell is 3.2V , LiMn2O4 is 3.7V . And LiMn2O4 can only be made for Pack under 15AH yet. But LiFePo4 has no limit.

So it sounds like they're saying LiFe is
better, but not
so much better its worth spending more for than LiMn, for 15Ah or less...?
The ebay page also says 70% of the weight of NiMH, which I don't see as correct if 36V 10Ah weighs 4.5kg?
