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

I looked into them a couple years ago as another way to save weight, but decided I just didn't want to spent that much money in order to gain ~100 lbs.
Advantages:
- MUCH less weight per AH
- Can be discharged to 20% charge without damaging the battery (meaning that 160 of those 200 AH are actually useful, as opposed to just 100 for a 200 AH lead-acid battery)
- Can be recharged 1000 or more times
Disadvantages:
- Limited maximum current draw (check rating on battery to see if it will work for you)
- Limited maximum charge current (check rating on battery)
- No Paukert Effect - when they're dead, they're really dead
- If discharged to shutoff, must be recharged within a (very) few days or they won't (ever) charge again
- COST!
