Which Batteries for Boondocking?

We mostly use camps with hookups, but we are also close to gov't parks where we need to boondock.

What batteries should we order with our new Greyhawk 20 MV?

We are brand new to inverters, converters, etc. so please go easy on me.

We have a generator but what do we do about powering a c-pap machine; using the house lights, etc. Can we make coffee? etc.

We understand using the generator for everything but that I allowed only 6 hours per day.

Thanks for any help with this.

Hard to beat Trojan T-105's - They are 6 volt batteries so you would need 2 of them, wired in series. This will substantially increase your ability to store power over what you have now. If you are using your converter, you are on shore power so you are already set anyway in those cases. When you are off the grid though, and you need 120 AC to run stuff that's where the inverter comes into play. Items that use a lot of power, like a typical coffee maker will kill your batteries pretty fast. Maybe get a percolator or a french press and make your coffee using your propane. The key point is you really need to calculate what your power requirements are *first* and then work your way back from there. Ask yourself how many days you will be 'unplugged' and once you've calculated how much power all of your devices use - in terms of Amp hours required for 1 day - you then have enough basic information to start looking at battery capacity needed, for the number of days you plan on being unplugged. if you want to extend that even further with solar, or if your generator (of unknown size) is up to the task of fully recharging you in the time you are allowed to use it. Unless your generator is very wimpy, you should have no problems fully charging the 2 batteries I mentioned first within that 6 hour window you have to work with. Just a few things to consider.

How old is your C-Pap machine? Mine has a 12V power plug along side the 120V power plug. If you can use 12V, it would be best just to install a 12V outlet next to your bed. To convert from 12VDC to 120VAC is very inefficient. I have never taken mine camping. But with an amp meter you could figure out what the power draw is, then decide on a battery system. You might be fine with a single 12V that can be charged daily, or you might need a dual battery system.

House lights work off of 12V, so that is a none issue.

Coffee, your best off not using electric. Best off finding a non electric method.

I am not sure, but you need to check the battery area in the Greyhawk. I know that there are some members that have said that he space (above and around) the battery is very limited and may be an issue for bigger batteries.

I am sure that some of the members that have upgraded their Greyhawk batteries will jump in here.

Depending on what size your batteries are (Ah) amp hour rating, you may be limited as to what you can run off your inverter.

If at all possible you do not want to run the coffee maker or the microwave off your batteries as they are power hogs. Your fridge, if it is a Residential model will kill your batteries over night. If it is a LP model, run it off LP.

The CPAPmachine, if it has a power transformer get the 12VDC conversion cord for it. Mine, when I use it, hate that thing, runs off the batteries overnight with no issues.

Coffee, I use the Mr Coffee, coffee pot without electricity. I took a Tupperware 2 cup bowl that fit in the Mr Coffee basket and drilled 2 1/16" small tiny holes in the bottom of it (see picture). I put the filter in the basket, add coffee grounds and insert the Tupperware bowl into the basket on top of the grounds. Boil 2 cups of water on the stove and fill the cup. Takes the same amount of time and used no electricity... best part the coffee tastes the same.

You can't go wrong with the Trojan batteries

My cousin has a 2015 Greyhawk and mounted the second battery in the rear storage compartment. He's been happy with the 12v but I've had better experience with 6v as 95% of our camping is boondocking. I've been VERY pleased with Lifelines in the past both in the boat and trailer.. so I converted my Redhawk to 6v's see below..

As others have said - check your existing battery compartment. There's NO room in our 31FK for anything much beyond one Group 27 battery.

You didn't mention budget. Batteries can go from *ouch* to "Oh my Jiminy - I didn't pay that much for my first car!!!"

If you have infinite cash, then look into Lithiums.
If you have finite cash but a fatter wallet than mine then it's Rolls/Surette and Trojans.
If those prices still make you wince, see if "RV AGM Batteries" will work.


As for how much battery do you need - that really depends.
We can make it one night - with medium use of stuff (TV, DVD player, 'fridge, furnace, lights). We need to run the genny the next morning to charge our single battery back up.

Use less juice and you can go longer.

Typically, 6V "Golf Cart" Batteries have more Amp-Hours, meaning you got more power in them. But now you need room for 2 - to get back to 12V.


Coffee pot? Ugh - the ones I've seen aren't light on power. They're not camper friendly. You could probably get away with it, but I wouldn't.

House lights - yeah. Even more so if you have LEDs.

I'm in agreement with pconroy. Minimize your use of AC/DC when boondocking. Use your propane when you can.

We've used a percolator coffee pot on the propane stove top for years. Quiet and efficient.
We use the standard drip coffee maker when shore or generator power is available.

X2!

When boondocking, electricity is the costliest resource.

We found the downside to using 2 6v batteries when one of ours shorted out. Normally (with 2 12v batteries), I would just cut one of the batteries out of the circuit, and I would still have battery power. Can't do that with 2 6v batteries... just something to think about.

Best solution that we found was to use a portable solar panel, that just set up outside... no installation required.
