There's no doubting the potential of lithium iron as Jeremy has said, but it's only available at an unacceptable cost to most at the moment.
The main concern I have with using continuous high discharges on them is how that will affect their life, even a three year life at those high prices being inadequate.
For me the best all round option when cost is factored in is still NiMh, even after their recent price increases. Once good ones are cheap enough, I'll switch to LiFePO4 instantly.
