2 12 volt batterys or 2 6 volt
what gives me the most bang for my money. every other rig that I have bought always had 6 volt battery's but the new one has 2 12 volt. not sure what works better.

6 won. 6 always wins. 6's rock. Oh yeah. But I do have some GP27...................RJsfishin wrote:

The folks who are out enjoying their campers. Not the ones who are counting cell caps on their batteries.- Ok, 6 pages, who won, 6 or 12 ?

I have used Trojan sixes in the past, so I am aware of where to look for them... And yes compared to the easy availability of 6 volters, they are RARE. So are all the others you list.
At least you aren't disputing the cost difference.
Which would cause the most inconvenience: If one of two six volts died while a hundred miles from the battery store or one of two twelve volters? Which scenario would ruin a camping weekend? My point is, availability is not a big factor to me. With the single twelve, I would have the luxury of time to replace it.rjxj wrote:

Wondering about that. Our new hair dryer has a low power setting that uses ~670W. Haven't tried it yet with our 1000W PSW inverter, but hopefully it works without blowing that expensive 75A DC fuse.
It would definitely be preferable to turning on the furnace and kneeling on the floor next to a vent, or turning on propane range and roasting my head over it (covering the flame with a cooky sheet).
I imagine the batteries will have to be well charged though, as I still only have 220AH in 2x6V GCs. The voltage drop could be substantial.
Once we get our tongue weight limitations fixed, I aim to replace those batts with a set of 4, doubling the AHs. Haven't decided on 6V or 12Vs yet, but will avoid AGMs as we're hard on batts. What with no generator, but 700W solar, they can be undercharged for days at a time when the weather/season is off. Like/need to equalize them asap afterwards. (Sadly, LiFePO4 is still too expensive for us).
Good, true deep cycle, flooded 12Vs might be the best replacements as our inverter usage seems to be increasing. Might even get a 2000W inverter some day!- What will a 1000 watt inverter run? Not a hair dryer, toaster, micro. I dont invert to heavy loads and I thought I went very overkill with a 600 watt pure for our 40 in led Television and trinkets. I just did that because I figure most of this stuff is so cheap I wanted to be very low on it power range for long life.
To go to the next step I figured it was more like 2,500 w. Maybe a 2000 if it was high quality like Magnum. SoundGuy wrote:

This being the case it therefore stands to reason that equipping a trailer with dual 6 volt deep cycle batteries is highly overrated as most My mistake... I thought that when you said "most" you were referring to others... Turns out it was about you. owners would rarely if ever fully take advantage of what those 6 volts have to offer and would be just as well served, if not better served, with a pair of 12 volt versions offering similar AH capacity.Huntindog wrote:
According to your logic, most people would be even better served with the smallest, cheapest SINGLE12 volt they can find.
If you are allways on FHUs, then 2 batteries of ANY type are a waste of money.
Nice try at distorting the meaning of my post but I also clearly said earlier on Page 2 of this discussion ...
"FWIW, I'm in the latter group as we typically only dry camp either because campground power has failed for one reason or another OR there aren't any electric sites available. During those occasions I do expect to still power a few appliances in our camper using my 1000 watt inverter so the ability of the battery bank to sustain heavy but brief loads is far more important to me than the ability to sustain deep discharging over many cycles."
Honestly, I did not go back and read page two.. That was history. I was responding to what I thought you were saying obout others.. Turns out it was about you.
My point is that although many may claim to dry camp the reality is that many, many more RVrs than not will choose to camp on an electric site and only don't when circumstances force the situation. AND as I clearly indicated in my earlier post I'm one myself who in that same situation would still like to use a few of our 120 vac appliances - e.g. toaster, coffee machine, etc - a case in which one would be in fact better served by a pair of 12 volt batteries that are better able than 6 volt batts to sustain heavy but brief loads imposed by an inverter My mistatake again... You were talking about your specific needs to power an inverter.. I thought you were referring to others... Turns out it was about you.but which would rarely see deep and repeated discharge ... and obviously 2 G31s would be far better suited to this task than a single G24. Regardless of how much you may try to distort what I've actually said my view is that many, many RV owners would in fact be better served by a pair of 12 volt batteries than a pair of 6 volt chosen simply because so-called "experts" on the forums falsely repeat ad nauseam on these forums that 6 volt batteries are "always better". Nope - not "always". :R
I highly doubt that most or even a high percentage have an inverter capable of running the items you mention.. Therefore, this has all been about you.- I'm "At Home Too" and a thousand mile round trip to a Wal-Mart.
Warranty? Shirley You Jest!
My CHEAPEST OPTION is to buy the very best most durable product on the market even if they cost three times as much. Four nights of hotels, 16 restaurant meals and $3.30/gallon gasoline + tires and oil ain't cheap.
The point IS
A person has to be anti-stupid enough to figure out what's best for them. Check unbiased resources like Consumer Reports. There are too many mitigating circumstances to declare something like "I use it therefore it is YOUR best choice hands down. Such declararions are the mark of an amateur. Huntindog wrote:

You do know of course that AGM batteries can be shipped to your home after finding the lowest cost source on the Net ... no need to drive anywhere.
How does that help if you need one on the road?
These are RVs... If and when something is needed, odds are you won't be home.
Availability IS an important factor for RV parts....
Good point ... from a full-timer's or long-termer's viewpoint.
We're only part-time RV'ers - our longest trip to date has only been 11 weeks. We are able to make sure our battery system is up to snuff before we leave on each trip, so we have no need to purchase more batteries enroute. Besides, when using two or more 12 volt batteries one of them will statistically always be good enough so as to be able to complete a trip with at least one usable 12 volt battery left in the battery bank.
