Hello everyone. New to the forums and RV world in general.

I have a 2016 Starcraft AR-ONE MAXX 19 BHLE. I plan on doing a good amount of dry camping but will be turning off the generator at night sometimes.

I want to get a deep cycle battery that is capable of running the AC overnight. I don't mind having to purchase two batteries and running them in parallel if that is what is necessary. Thank you.

You wouldn't be able to carry enough batteries to handle the load.

You're talking about a $6,000 plus investment in Lithium batteries, solar panels, inverter, solar charge controllers and a complicated mess of wiring to run an AC for just one night of cooling. And if the sun isn't shining the next day you better have a $2,000 generator to recharge your batteries.

What @rjsurfer said.

I came across a youtube video of a guy who set up to do that, but he was running a 5,000 btu, energy star AC, not the 13,500 btu unit on your camper. He did it with 600 watts of solar JUST FOR THE AC, 1100 watts to run everything else he wanted to run, and several Lithium Iron Phosphate batteries. Unless you downsize your AC, you are going to need a minimum of 2,000 watts of solar, and a dozen or so of those lithium batteries. Merely buying another flooded cell lead-acid deep cycle battery isn't going to do anything useful for you.

A 12A A/C will draw about 130A from a 12V battery. 2 6v deep cycle batteries at 220Ah can supply 130A for 50 minutes to the 50% level. That works out to about 20 6V batteries for 8 hours and about 1,400 lbs.

Run the gen all night.

Or you can set up a 48V lithium battery set which will be less weight and can discharge to 20%. Then run the gen all day to recharge. And the cost will be $$$$$$$, if not more.

Hopefully it gets cool enough at night that you don't need the AC. You can't run it with batteries.

Two of these should do the trick:

Do some basic RV electric online reading that includes a discussion of volts, amp hours, inverters, deep cycle batteries etc.

There is one other option not mentioned. Stay at a hotel.

As stated it can be done but it is costly.

Most are figuring you need so much power to run 8 hours a night 8 continuous hours. If running off genny all day and the trailer is already cool I would say using batteries 8 hours per night the AC would probably cycle on and off all night probably running at 20 minutes per hour on avg.

You could get away with 3 100AH Lithium batteries, a good charge controller and inverter. Solar panels would also help and can be had on the cheap around 100 a piece. The expensive part are the batteries, charge controller, inverter, etc.
Here is a link to a package for example https://battlebornbatteries.com/shop/chickery-travels-300ah-lithium-bundle/
You would also need to add a micro air easy start to the AC for it to ever start off of batteries. This kit with 4 solar panels, a 3000 watt genny to run the ac during the day and charge the batteries at the same time as the solar is helping will be in the $8000 range to have this all done and working properly.

Some people say holy **** that's a ton but if you really love to boondock and that's the primary way you want to camp and you have that investment for 10 years that's only $800 per year over that 10 years. Most spend alot more than that per year on full hook up campsites at moderate resorts per year. Heck you could spent that easily in 1 week per year at a nice resort campground.

It honestly is all in how you want to use your rig.
