lithium batteries
Has anyone ever heard about using lithium batteries in a RV?

I've been thinking about it! I have 8 130ah 3.2v cells (that makes 260ah @ 12v) that I've pulled out of my electric car. These cells no longer support the current I need in the car (500a or so), but are more than adequate for the 5-10a that I need in my trailer. It's sort of a longer term project for me since I have more important things at the moment, but I will be installing them eventually. :)
These cells cost me over $1000 when I bought them, so obviously it would not be cost effective in this application. But since I already have them now... why not experiment?
btw, they weigh 9.7 pounds each, so 260ah @ 12v would weigh under 80 pounds. And that's about 200 usable ah's, none of this 50% discharge limit stuff. The equivalent of 200 usable ah's in lead would be more like 240 pounds (four T-105's).
(edited cause I had some of my numbers wrong from memory)
