Thanks - I have seen the headway cells before, but they are actually more expensive than the GWL 10Ah cells - rightly so, as they can handle somewhat higher currents.

I have been looking at A123 pouch cells for the same reason; those are relatively light so I could increase capacity without losing portability.

But I don't expect a very high current.
I figure that if I can get the cheapest LiFePO4 cells that can produce 20 Amps continuously I'm good. It rules out A123 cells and probably Headway cells too.
I may be wrong in this though. I'll keep an open mind.
