Lithium RV batteries?
Check out these lithium-ion batteries in marine/RV/deep-cycle configs here.
Pricey to say the least. One 300AH 12 volt for $3000 - sheesh. Anybody using these?

Santiago, RV tech forums have really batted this around. Everybody figures that the "ultra-comfortable" pusher-bus class of RV'er, the type who would
never join in on a forum discussion may be buying them. :-)
Like anything new, I figure LiH batteries need a few years of knocking around to figure out whether they are really durable. They sure are
lightweight, but I remember reading somewhere that cubic inch per cubic inch, they do not have the same amp hour capacity as a standard flooded lead
acid battery.
But my hunch is this is the wave of the future. A welcome one at that. Thanks for sharing.

I just bought a group 31 Lifeline from an outfit in Texas called Centex. This was a GPL-31T and it is not a Sun Xtender, it is the Lifeline line from
Concorde.
290.00 shipped to me. 278.00, if you can pick it up at his place outside of Austin. A group 31 is the largest battery I can put in my cabover camper.
But with my solar panel and charge controller, I can generate about 7amps @ 12v on a good day.
I'm very happy with the price. And NO CORE CHARGE.

they just got approved for airplanes. when my current sealed gas recombinant unit finally gives up in a few years not before hopefully - i will go to
the lithium ion for many good reasons especially lighter weight.

They say 10 times the life and my numbers show the cost over my T105's to be 7.5 times so, in theory, they should be cheaper. If you can get past the
initial $$ outlay. My other hangup is I may not be around long enough to get all my use out of them.

The Centex guy reports the life expectancy of a well-tended Lifeline at between 7 and 14 years. Generally, the guys who get 12-14 years live in cold
climates and use temperature-compensated chargers or charge controllers. Heat is a huge enemy of batteries, more so than cold, as long as it doesnt
freeze.
So, I hope to get 7 years. By then, maybe the big LIo batts will have come down through economies of scale of the manufacturers.

How about a battery Pack such as that used in a Prius or similar electric car. They would be a lot cheaper than a single $3000 battery, even if the
system costs $7000.
