Anyone Install Lithium ion Batteries? Results?

Ok I went to that Manzanita website and they do have a nice packaged solution for Lithium cells, but a 13V 180AH pack is $1564.

Four of those would be $6256 compared with four Lifeline 300AH 6V AGM at $400 each or $1600.

At that price you could buy almost 4 sets of AGM and get at least 4000 cycles from the combined sets over a 16 year period. (Figuring a 4 year 1000 cycle life for a AGM).

It all comes down to weight. If you need to save the 500 pounds, I would give lithium a big positive.
