Default Best batteries for boondocking

We have 1 100w solar panel installed and as Jack&Janet predicted were ardding a second.

In the meantime we need to upgrade our two marine/rv batteries to something more robust. What have you all found works best? The Golfcart batteries I've seen look too tall for the compartment on our 2005 17T.

I'm looking at proper deep cycle batteries and thinking of even going for lithium ion.

Montana - Lithium would be VERY expensive, I think.

I'm able to put two Group size 24 wet cell batteries in my trailer. Others have room for the larger Group 27s, which give you more capacity. If you could fit the two 6V golf cart batteries in (wired in series) they should be even better (more capacity). The goal is to keep the charge state in them as high as possible, so, more capacity = a higher average charge state and should give you more life. But, I think your trailer is like mine and you will only have room for Group 24 without building a bigger battery box. That project is something one member did - you MAY be able to find his post. I think it's fairly "doable".

I would NOT try to use the "gel" batteries. They cost about twice what a lead-acid battery costs and don't really give you significantly more capacity.

The problem with Lithium-ion is that the technology is still awfully new. They've had some widely publicized problems, such as overheating in cell phones and a fire in a Boeing 787 Dreamliner. Besides the expense, I simply don't trust them. My power tools use them and so do my laptops and cellphone, but I would not want them in my trailer. One interesting fact about Lithium-ion is that the ideal charge state for storage is 80%. I think that's pretty much the desired level when the things are in use too. I don't know how the heck you can maintain that level without special electronics.

DaveL put a pair of 6 volt golf cart batteries in his 2409T by lowering the battery box a couple inches. He said it was an easy task by extending the length of the mounting straps.

Another argument for 12 volt batteries over six volt is that if one battery goes bad in the 12 volt arrangement you still have at least one battery that is useable. In a six volt series-wired set-up, unless you have TWO banks of batteries ( four total), if one goes bad you are essentially without electricity. Gel cell and the "matt" battereies ( AGM?), often need different and touchier re-charging set-ups in terms of charger/converters and charge controllers. Unless you are really into all of this and enjoy it-I would recommend shopping for good, deep cycle, 12 volt wet cell batteries. Its the easiest system to use for these trailers, in my opinion.

12 Volt deep cycle batteries are easier to find in a pinch.

I'm wondering if I could squeeze in group 27s. There's a lot going in that battery box.

I found one on Amazon that measures 12x6.7.
I roughly measured each battery space at 11"x7"

Based on my trailer, which should have the same sized battery compartment, I'd say no.

True, but if one 12v goes bad then it continually drains the good 12v battery until it is also dead, and if not caught the good battery will soon be a bad battery. You would have to catch it going bad pretty quick to disconnect the good battery, or you would have to recharge the good battery, which is not an option with 6v. But, if you can recharge it then you can supply the same 12v over the good and bad pair of 6v batteries and at least make the lift.
Ive never heard of one 6v going bad, but Im sure they do.
Maybe set your pair of 12v batteries up so they are separated from each other yet still power the same electrical system, if that is even possible…
To me is not enough of an issue to leave my pair of 6v batteries.

Default Universal Battery UB121000 AGI

I'm looking at installing a Universal UB121000 battery in my well behind the tongue. It's a size 27.

Two questions?

Has anyone put one of them in your tongue well? Although the height dimensions says 8.2 inches, it's actually 9.1 inches to the top of the terminal. I think that would barely fit, but thought I'd check first.

Also , it's rated fairly high for a deep cycle battary, but I can't find any CCA on it. So, will it have enough power to lift my trailer up?

Ken
