RV batteries?

[tubby]

Recently purchased a 18ft travel trailer. Battery had some issues and now am looking to replace. Heard people are getting some very long life on the tandem golf cart batteries. Almost all camping is done away from hookups.
What are you using? Recomendations?

[wrenchhead]

Yup two 6v batteries run my 21 foot unit for a three day weekend with a family of 4. Got to be a little careful if I run the furnace though.

[dasnake]

I have a 9.5 camper, run 2 12 volt deep cycle with an isolation switch, usually by a tree for 2 weeks or more, I always use a Honda 2000 during that time to charge up the camper batteries and run the battery tender for the ram.

[Budman]

I use 2 - 6 volt golf cart batteries and they last for 3 days no problem . They are used in my Kodiak camper.

[Pemby_mess]

Look into AGM batteries for sure - worth the money. There's no comparison for something like an RV

[Fixit]

trojan t-105 or t125's (6V golf cart batteries)

If you are off grid, 2 deep cycle 12v will do, but you need some form of replenishment, be it genset, solar or both. What you take out must be put in. The bigger the Amp Hour rating the better. But it all comes back to replenishment. Oh, and running your truck will do very little or practically nothing to bring the batteries up unless your are driving all day long. The other thing that you must consider is that both batteries are equal. The higher battery will discharge to the voltage of the lower battery.

Good post! I've boon docked 3 times this autumn for between 4 and 7 days. I have 2 12v deep cycle batteries
that are used independently because they're of different age. I use a gen during the late day, evening, and morning
breakfast time to supplement high usage (micro wave, toaster, coffee pot and furnace) which I also plug a battery
charger to in order to rebuild one battery at a time.

27 foot trailer. First thing I did the day after we bought it (new) was put 2 golf cart batteries in it. That is what I used as house batteries for years in my ocean boat.

Love them.

2- 6 volts are your best bet if they will be designated RV batteries but you might consider 12V if you plan on stealing one for an electric boat motor.

Yes, that is what I do frequently, lol!

[dasnake]

One more tool to remember, if you go 12 volt, remember deep cycle not starter batteries,, I'm not being funny, there is a big difference, grand canyon big.

[scoutlt1]

There's something to be said for using 12V deep cycle/starting batteries all round (and packing even a small genny)...
They don't last as long as two 6V for sure, but at least one can serve as a substitute battery for your truck.
I carry four. One is in my Jeep (obviously), one is for my trolling motor, and two are for my trailer.
Jeep battery died on a 10 day trip once.....I was glad I had a spare to get me home.

We have two 12v deep cycle batteries and we carry a 2500 watt genset.
It was bought 10 years ago from KMS tools and is a cheap knock-off copy of a Honda genset, best money I have ever spent.
I can let it run for hours, charge batteries, run a string of lights for butchering etc.

[frase]

Have and old camper for hunting and one Costco 12 V deep cycle last a week in cold weather. Only use it for lights. Usually carry a back up battery or gen set just in case.

[Bowzone_Mikey]

I run a set of 6v in my 34foot Class A ... all LED lighting where I can have lasted 5 or so days ... off grid ...

that said I also have a small solar panel that tops up when hooked up properly and if need be I have a genny ...

for shit and giggles I disconected the solar panel for a trip to see how long I can go and it was 5 days solid ... granted the furnace wasnt used much(just one night got cold)

[tubby]

Thanks for all the input. Gonna get tandom batteries and either 2000 or 3000 watt generator!!!
Gonna be nice in the trailer instead of the camper!!

[widger]

I also went the route of two 6v for my 23' travel trailer. We have gone up to 5 days without hookup depending on what you are running. Gen set backup is always nice to have.

[One Shot]

We have 4 - 6v deep cycle batteries in series and parallel to get 12v. This is also connected to a 180w solar panel which recharges the batteries to 100% in the wee hours of the morning. If we need 120v we have a inverter or for longer periods and or more wattage uses we have a 4000w built in Onan gen set connected to the system.

[NORTHERN HUNTER]

2x 6 volt Interstate deep cycles and a couple coleman 40 watt solar panels. Works excellent for a few days.

[Skidood]

Out of curiosity, what is the reasoning for 6v vs 12v? I can get 4-5 days out of my two 12v deep cycle, depending on how much the furnace runs of course. This is also on the Island in October/November with frosty mornings at the worst and not too many negative temperatures to deal with.

[Bowzone_Mikey]

6volt batteries have more AH rating than 12volts

Storage capacity is everything

good Vid here

Gonna be nice in the trailer instead of the camper!!A 2000 watt is lugable and a 3000 takes 2 people and barely fits through a trailer door. Just sayin'.

Make sure the trailer has a good 3 stage charger and measure the battery compartment (and door) for fit before buying some batteries.

Hmmm 2 x 6 volt Trojan t- 105..with solar panels..good to go..

I used 2 6v batt in Sumer for 10 days. No furnace run time. Batteries still at full on meter.
3 days in sub zero temp with the furnace running Reg till my buddy got bored and started the 2000w gen up to be able to watch a movie. Batt was still at 3/4 at that point. I recommend either Yamaha or Honda 2000 w generators of you need to charge batteries. But not big enough to run Ac unit

[Cpl_Punishment]

Where are you located? Long story short, I have two newer Interstate 6v batteries that I'd let go for $250.

I had plans to go camping last May, went and picked up my trailer and my batteries were DEAD because the last time I used it, my truck fuse was blown. Because we were leaving early the next morning I didn't have time to charge them, so I went to the RV dealership and bought 2 new ones for over $400 and used them for 1 week. When I got home I charged my old ones and they have been fine ever since. I have since re-charged the new ones, and they have sat ever since. I initially thought I would keep them as spares, but I don't foresee using them.

I'm in Langley. PM if interested.

Absolutely the way to go! I have the same batteries with 400 Watts of solar feeding them and a 2500 Watt Inverter, keeps things going quite nicely, may add two more batteries to give me longer sustain times but so far have not had the need.

[Buzam]

Also, replace all your lights with LEDs to save power. I ordered a bunch from a hong kong based seller on ebay when I first got my trailer 4 years ago and have not had one problem with them.

[savagecanuck]

I've been running 2 6v batteries and a solar panel on the roof with the proper charging unit. My original 6v Batts died last winter after 9 year's. I bought 2 new ones from Costco last spring for just over $300.Was hunting ,camping last weekend with the furnace running and power was never an issue.

Savage Concepts Canada on Facebook has LED RV bulbs cheap and he is based in Cloverdale. They warranty them for 1 yr as well. They seem to have better quality bulbs too. Pricing is around $5 a bulb depending on type and size. He has a good selection in stock. Tedco RV in Brookswoodalso has LED bulbs at reasonable prices as well.

I run 2 - 6 volts, interstate extreme I believe. I usually turn the geny on in the morning for the coffee maker but I could go for 3 days using the furnace.

If your thinking of getting a geny don't bother with bigger than a 2000w unless you want to run AC..

[Edzzed]

we use 2 12v batteries in our trailer. We can go 5 days easily. That's without using the furnace. I also changed out every bulb in there for LED panel lights. https://www.wish.com/c/5644546837c44737776dec92 That also includes the bulb in the fridge. We also have a small Honda generator to top up the batteries. It works well enough to grind coffee or toast two slices of bread. Won't do 4 though.

[sdurango41]

We have two 6 V batteries in tandem and also swapped out all bulbs for LED. Just got back from a 9 day moose mule deer hunt with furnace on at night before bed and in mornings. Bulbs did not even dim over the whole trip. Even when the water pump kicked we had no dimming/flickering of lights. Key is to keep them topped up when trailer not in use. We go out and plug trailer in for a week or two to top up batteries and then unplug for a few weeks after that. Works well.

Have 2 new 6 volts in my older Nash Trailer.Just spent 12 days at about minus 4 at night.Would have to charge up with the Genny daily for a few hours if sunny during the day but when rainy and cold and indoors for a few hours during the day i would run the genny longer to keep the batterys striong for the night.And used about 70 ilbs of propane.
