If you wire those in series the lights are brighter, you pickup more television stations, and they glow in the dark...

I know it looks comical but we love having them.

I installed those in 2010 thinking with a genset to recharge I'd be able to keep my mothers oxygenator running each night on a epic journey that ended with a week in Yellowstone. (Custer's Last Stand, Devil's Tower, Mt. Rushmore along the way).

I learned the hard way what a poor recharging system comes standard in our TT. We'd start the generator at 8:00 am and run it all day, while we visited the park and return home to turn it off at 8:00 pm. Only to hear the low battery alarm going off at 7:30 am the next morning.

Installing extra batteries is only the starting point. Then you need a charger/inverter to use them to their potential. And so the money gets spent installing more & more mods. I've done many mods since then and still learning the hard way. Woke up once freezing to find my son had started the air conditioner while I was sleeping. Left the "Auto" selection on the fridge and ran the fridge on AC power from my batteries for 12 hours. Those situations have you discover the true power in your battery bank. Fortunately in those neither one killed the batteries or ran them too low, (air conditioner ran them down to 37% though and that is below desired maximum 50% discharge. Good news is we just finished our 5th season on them (Costco golf cart 6 volts in series/parallel) and they are still very healthy and strong. Would love to get 7+ years, we'll see. Maintenance is everything. You've got to check the specific gravity and keep the fluid level where needs to be and keep them on a charging maintenance schedule year round.

Unless you are boondocking for a very long time and using an inverterter to power up 110 devices, 4 6V cart batteries seems like a pretty extreme overkill, especially when you have a gen to do regular recharges. Those things are heavy and adding all that to the tongue can't be a good thing. 2 6V carts should run the med equipment along with basic 12V needs for 12 hours or more without a damaging low charge level on the batteries.

I knew that you were joking when I got to the part about more tv channels when wired in a series...anyway I'm looking at 2 group 29 bat .parralel gonna try 150 watt portable solar panel to recharge and if need be plug in to my running truck.
On one battery in my popup I could go a couple of days with no problems using furnace at night and standard light bulbs. I just changed out to leds on TT. Inverter is the next thing I'll be adding once I see how the 12 volt stuff works. my batterys have a 2 year free replacement warranty so if I go below 50% enough to wear out I can get replaced

You put all that $$ into batteries and inverters and didn't add a stand alone battery charger?

What size inverter did you install? Never heard of anyone running an A/C system off a battery bank/inverter. If the fridge was set to auto it is going to run on a/c if its available.

Well we usually run the battery bank down with our normal day to day usage to a 57% level. That includes using the microwave to pop some popcorn and watching movies. My wife has a pain condition that can keep the Television/DirectV on until 3 or 4 in the morning. Then I typically brew a pot of coffee (6-8 cups) and wait until the 8:00 am protocol to start the generator. The typical NP protocol will allow generator use from 8:00-10:00, 12:00-2:00 and 5:00-7:00. We typically only need 3 hours of generator time to fully restore our battery bank. To answer your question, I installed a 3,000 watt inverter with a 4,000 watt surge and it has the ability to utilize both shore & battery power to create a continuous power source. My wife is disabled, so we have unique power requirements. Please don't judge. If you'd like to see the install of this amazing inverter/charger see the attached, bassdogs.

Here is the most awesome inverter/charger you could ever hope to have in your TT.

No judging from this camper, just doing the math and running A/c thru an inverter with 4 6volts and a3000 watt inverter will work, but not for very long. Factor out the A/C and allowing for an occasional use of the coffee pot or microwave and 2 6V's will get you thru to the next morning. If you've got access to shore power, the battery bank/inverter is only for back up. If no shore power, your formula works except for the A/C.

Edit - ive don't some more searching and it seems getting another batter is ok. please let me know if you think otherwise. thanks
Have the dealer take back the 12V deep cycle and install (2) 6v batteries. the cost difference might be minimal.

Yeah, the incident where my son ran the A/C was a no-no and he now understands the batteries are NOT for air conditioning. I'd say 95% of our camping, is dry boondocking in the woods without shore power. When we travel cross country we'll use the occasional RV park so the kids can have a pool to use, but we are not into RV parks. We like the woods, I will say more and more of the Montana State Parks have begun placing power pedestals but most CG's do not. The most shore power my unit ever sees is when it is parked at home. The goal to never goal below a 50% SOD (state of discharge) we can easily accomplish with our normal routine and have a little buffer to boot. The four Costco GC-2 golf cart batteries we purchased in April 2010. They are holding up real good. I keep tight on the maintenance for them. Hoping to get a 6th or even 7th season out of them before we have to replace. Then I'll probably upgrade to "Crown" batteries 265 AH each. That would move us from a 440 AH bank to a 530 AH bank. Plan to put a 1000 watt solar system on the roof this spring. Ideally I'd like to dry camp, and have all the power we need without even using a generator. That opens up more terrain to camp in places like Yellowstone on some of the CG's that do not allow generators at all (Lamar Valley). We have a real good handle on what we use and what we need. May be a bit over engineered but I never worry about power.

But you're right, the goal is never to run A/C with batteries.
