Rob-
 Lithium cell batteries are great, and may in fact be the cheapest batteries in the long run despite having the highest up-front costs. But they're not quite perfect. If they are overcharged, or undercharged, they can be killed surprisingly easily. And that means a good battery management system, and if that fails, the batteries are toast again anyway.
 But if the user is very much aware of their limits, and keeps them within those limits, they're great. Especially the LiFePO4 chemistry, which is the least powerful type, but the only type that doesn't use a flammable electrolyte.

I'm playing with LiFePO4 cells and a solar panel currently. Once I get past the cell balancing stuff I think I'll be a happy camper with a battery that weighs about a third of the lead acids...
