6 volt batteries?

Hi. Newby here. I have a 196 Surveyor, and we want to dry camp a couple of nights. I currently have a 12-volt battery. I understand that a good way to get more battery capacity is to get two deep cycle (golf cart?) 6-volt batteries and run in series.

Could someone pls let me know: what is the usual size/brand 6-volt battery and where can they be had at the best price?

thanks in advance!!

Rich

I like interstate u2200 batteries anywhere there is a authorized dealer in your area.

Trojan T-105s are a very good quality and popular choice for a 6-volt system. I am not sure who would have the best price.

Just be aware that although 6-volt batteries are popular and have advantages, they do have some disadvantages. Their primary advantage is for those who do not have or do not wish to use a generator and plan on camping for extended periods on a regular basis, usually 4+ nights.

Some of the disadvantages are:

1) If you are going to use 2 6-volt batteries in series and one goes bad, you are out of business. If you have 2 12-volts in parallel, you can isolate one and continue on one, although at an obviously reduced capacity.

2) In the event you are in a rural area and do need to replace a battery, 6-volt batteries are not readily available, where as most small towns with an auto parts store will usually have some type of 12-volt rv/marine battery. It may not be exactly what you want, but can get you back up and running.

3) In the event the battery in your tow vehicle dies, 6-volt batteries have no cranking amps available with which to start your vehicle. 12-volt rv/marines can be used to jump start your vehicle.

If your intent is to dry camp for just a couple of nights, 6-volt batteries are not really necessary. In my case, we "dry camp/boondock" on a regular basis for up to a week at a time. It is not uncommon to have a 50+ mile drive for any type of supplies or services. I have 2 Honda EU2000i generators with a parallel kit so I can recharge and therefore running out of power is not a concern, I just want to be able to go a few days without running the generator. I therefore decided on 2 12-volt batteries (Trojan SCS225s) in parallel. They allow me to go 3 to 5 days before I need to recharge. I have the advantage being able to jump start my vehicle if needed, running off one if needed and if I do need to replace one, it is generally easier to find 12-volt rv/marine batteries in small towns rather than 6-volts. It is all about staying in the game.

If I were going to regularly camp for 4+ nights without the use of a generator or solar panels, I would most likely have gone with 2 6-volts in series. Just something for you to consider in your decision. Good luck and happy camping.

We have one Group 31, 130 amp hr, Trojan 12 volt deep cycle and can generally go 3 days without running our generator; but we are careful, have no kids, converted to LED lighting etc. If the furnace needs to run, we don't get 3 days; more like 2. We turn our heat down to 50 degrees at night. Early season and late season are the toughest; more darkness so more lights, and colder so more likely to need the furnace. A weekend is very doable though.

Batteries

Thanks all. Maybe I'll just stick with two 12V batteries. I do have two, but only one is mounted. I can extend the platform on the tongue and mount two. Is there somewhere I can buy an electrical harness to connect two batteries in parallel, or do I need to make one?

Just need to get battery cables of the proper length like the Ford type that go from the starter to the solenoid as they have eyelets on both ends to parallel the batteries

The batteries do need to be identical in order to parallel them. You would need to have a tray for two batteries anyway if you were to go to 6-volts, so you might as well try the 12-volts if you already have them. What is their 20 hour Amp Hour rate?

I don't know their 20-amp hour rate. They are small 24 size deep cycle. One says 75 amp-hours. I may size the tray to hold two larger size batteries for when they wear out.
I don't think we will be doing a whole lot of boondocking, maybe one or two days at a time max.

Rich,

My Deka DC-24s are 75 amp hours so that sounds about right for OEM Deep Discharge batteries.
