Battery Charging While Camping

Please feel free to point be to another thread, but my '63 Safari only charges when connected to the tow vehicle. That's fine, but I would like to have the 12v kept charged when camping to run my fan and ext. light etc.

So, can I connect to city power at the camp ground, plug a battery charger to one of the 120v external plugs on the camper (in case the camp ground only has 30 / 50 AMP connections) and charge the battery that way while in use?

Any recommendations on small quality chargers for this purpose would be appreciated as well.

Keith

Is the converter in your Airstream not working at all? The converter should charge the battery in your Airstream when plugged into shore power. The converter should also run all of the 12 volt DC components in the trailer. We need to know a little more of what's going on in order to give proper advice.

My '58 was wired the same way originally. What you need is a 45 or 55 amp charger/converter. This unit, which converts 110v AC to 12v DC, will charge your batteries while plugged in to a 110v receptacle, 30 amp service preferably. It will also provide 12v to your trailer if you were to remove your battery for whatever reason. The Intei-Power unit below is a quality three-stage charger which is what you need. It won't boil your battery(ies) dry.

Thanks Brian, the 63 has no converter, it only charges off the TV. I really don't want to add anything to the TT permanently so I was looking for something I can just plug in and use when camping.

Adding a converter/charger would be a lot easier that hauling around a battery charger and hooking it up each and every time you wanted to charge your battery. Converter/chargers are VERY easy to install. Does your trailer have a 12v fuse panel? If you do, all you need to do is hook up positive and negative leads on the converter/charger to the fuse panel then plug it in. Piece of cake.

If you are absolutely against the idea of adding a converter/charger, then yes, you could buy a battery charger and hook it up to your battery. But that would be a pain. You'd have to put it away at night or when it rains and these battery chargers are NOT smart chargers. They will boil your batteries dry if you leave it plugged in.

Thanks Indy, I think I may be leaning that way, just trying to be cheap but probably at the risk of being unsafe.

Hey I looked at your blog, nice TT. Where did you get the new entry hiding step? Mine could use a replacement.

Thanks Mike,

OK OK, I'll quit being a cheap lazy ass and do the right thing. My circuit breaker box is in the rear storage compartment, not a lot of room back there, do these babies need a lot of clearance?

Thanks guys.

OK, last question since I have your attention. If you could help me understand how this works from a wiring perspective. I have a battery that drives 12v only. It has a 12v connection coming from the tow line and one going out to the 12v circuit. That along with a ground.

Where does that 12v connection come into contact with the AC circuit breaker in the back of the vehicle? Are the 2 circuit breaker back there split 120v and 12v? with the 12v feed off the battery going there first?

It's raining here today, so I think I'll go home and do this in the rain ;-)

The only connection would be the converter, if you ad one. A converter takes 110 AC and converts it to 12 DC while monitoring the battery charge. A cheap battery charger does the same thing, but does not have the monitoring ability and is meant only for short use.

The fuse panel is different than the breaker box. The 110 AC system uses the breakers, while the 12 DC system uses automotive fuses. Again, two separate systems.

If I were you, I'd install a converter. Much less for you to deal with once you complete the installation.

I agree it's well worth retrofitting a converter. Also will be a good resale point. But if you use the external battery charger use one which will shut itself down when the battery is fully charged so you don't fry the battery.

I second the motion to contact Randy at Best Converter. Tell him ALL the parameters of your situation: what you got, what you don't want and why, and what you're trying to accomplish when you are all done. He listens well and will discuss why a particular component is desirable. Personally, I've gone with solar battery charging for two trailers now (in addition to my home), and am convinced that it is the least trouble and expense in the long run, though not the cheapest in the short run.

And for least first cost with reliability and low maintenance, I would highly recommend a good quality converter to intelligently charge your batteries when AC is available. No substitute for good quality and high capacity deep cycle batteries.

Never forget that cheap is not the same as inexpensive. jim

Yes you can use a charger plugged into your 120 outlet. I did this for almost a year cause my converter would not charge my batteries. I have a good 3 stage charger and it did the job. I finally this spring installed a Progressive Dynamics 9200 45 amp converter and it was easy to do and works like a dream. It really was a lot easier than I thought to do.

Good luck,
Tim

Since your trailer is wired so that the lights etc run off 120v when you are camping, and since you intend to leave it that way, a small converter/charger is all you need and will keep costs down and give you a smaller, lighter unit.

I installed a small marine battery charger/ maintainer to charge my battery every time I plug into shore power. I still use the seperate systems the 63 came with. 110 volt s while i'm pluged in and 12 volt when boondocking. Check my pictures, I posted one of the charger setup a while back. It works great for me and keeps it simple.

I may be naive, but . . . (external float charger options)

I am thinking along the same line as the original poster. I have a "smart" three stage float charger that I paid $70. I have used it to charge batteries at home before I leave to go camping in my 1972 Globetrotter. My trailer does not have a converter/inverter. I do have easy access to my battery compartment. I have a small generator.

I would like to simply plug in the external float charger into an AC 120V outlet receptacle in the trailer. Then plug the shoreline power cord into the generator to provide power to the AC 120V receptacle in the trailer.

Can I leave the charger hooked up to the battery while running 12V, or do I need to disconnect the battery everytime first?

If this won't work, can't I use a male 7 pin adaptor in the same manner?

I know this is skinning the last cat, but my motivation is money. I have exhausted a lot of it on a complete axle. I don't want to buy a converter/inverter right now. I don't have one, so both AC and DC are independent as of now.

Any Help Appreciated

I had a similar issue and have been too busy to tear into it, so as an interum solution - I added a 2amp trickle charger, added an on/off switch and while it's connected to shore power switch that thing on. It automatically shuts down when fully charged. I have it connected directly to the battery. The brand is Peak and is sold at Pep Boys for about 20.00. Very small and compact and works great for now.
