lithium batteries

I cannot see how someone can read through the posts on this thread and say "Nope" no one is using lithium in an RV.

We have been using LFP (9.6 kW-hours) for 14 months with great success as has Ron Jones for the last two years - and Liberty Coaches has also been using them exclusively for two years on their $1.8M and up Liberty Ladies.

I use my cordless drill with a lithium battery in my RV..:W

Short answer = "NO".

Also - try your question (or a search) in the *Technology Corner* -or- *Tech Issues* forums (here).

Where do you winter in Mexico. We have spent time in Baja (not mainland of course), San Miguel, Puebla, and Orizaba but primarily in Yucatan. Last trip 16 months ago we made it to Belize and Tikal. Tikal is as far as we ever plan to go in Central America since roads really are not for 34' fifth-wheels. We met a lot of folks who do go further (like Argentina/Chile further) but they do that in Class Cs and Bs and they are primarily French and German.

No one wants a fire or explosion; LFP may be particular but is readily handled by proper controller and battery management system.

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)

I hope you can get a proper charger for them Li batteries are very particular feeders. You don't want a fire or explosion! :E

You missed Chevy Volt fires. And it is only the 787!

Thank You for the correction..

I keep forgetting Chevy makes the Volt. or the Volt is a car.

Help me out here. What chevy volt fires. The only one I can find was the volt that they put through a simulated crash test and they didn't disconnect after the test and before they put it into storage. (which is supposed to be done on any car crash test) Were there other chevy volt fires? Thanks in advance.

Here's an interesting battery comparison chart that may help to put into perspective the supposedly extra cost for the particular lithium batteries shown in the link that I provided a few posts above:

The prices are definitely coming down. If we were to have system designed and fabricated this year, we might well go with these Balquons since price is down by 25% from last year.

If I had the nearly 4,grand to use that 300 amp hour one I'd give it a try.

But just now.. NO A CHANCE.

they can be had for better prices

200Ah for $1430

700Ah for $3350

1200Ah for $5250

700Ah @ 24v - 1400Ah equiv. for $6650

I was told they have a 400Ah @ 12v version too for $1920
