Hi ByTheRvr,

Running the RV without a battery depends on the make and model of the converter. Don't do it until you know it is safe to do so.


Regards, Don
Kustom Koach Class C 28'5" 256 watts Unisolar, 875 amp hours in two battery banks 12 volt batteries, 2500 MSW watt inverter.

  • I used an old car battery, just one, and the only thing it was used for was powering the LED lights.
  • I'm told the typical 7 pin power connection isn't enough.


I haven't figured out how to quote yet first try.
I would just get the right kind of battery and make sure the vehicle charger is working correctly before I put out any expensive fix. My vehicle was not charging the battery and it was just a blown fuse in the TV.

Hi Brooks,
My other TT has all LED lights and I used a car battery and my 7 pin connector worked fine for keeping the battery topped up. I'm in a completely different ball game with this TT though.

Hi Rvr, My old pioneer 180CK had 2 6V golf cart batteries. It was equipped with all the stuff, including the always on safety devices. When we camped in the cold using the heater, I don't know how many BTU's, we were good for at least 2 nights. I tried not to let the deep cycle batteries get below a 50% charge. We used the stock filament lights, DW always left the over stove light on. We took showers, ran the fridge, cooked and did dishes. We only used the heater at night. After towing 5 or 6 hours the batteries were at near if not at full charge. That was my experience. I just got a new to me 26RL with group 24's. My new experience may be like the one you are going through now, guess I'll see.
May good luck follow you.

Hi Brooks,
You have me a bit confused. In your first reply you mentioned you had heard the 7 pin connecter wasn't very good for recharging the batteries and in your second reply you mention how you used your appliances and and a few hours of driving the batteries were recharged. What sort of connection did you use if it wasn't the standard 7 pin?
Thanks,
Barrie

If you have not bought any batteries yet you are a good candidate for two 6 volt batteries in series. Costco has the GC-2 golf cart batteries. Those are probably the best bang for your buck, especially if you do not have two 12's now. You only need one battery to battery connector. You will be surprised how well they do.

The standard 7 pin connector should work fine. If not use my 12 foot jumper cable procedure when you plan to be in one spot longer than 4 days.

Thanks for the advice. From everything I have read I'm convinced to go with 2 x 6v golf cart batteries in series. If I use the jumper cables to recharge the batteries, do I connect the negative terminal on one 6v and the negative terminal on the other 6v?
Thanks

you will need to connect the (-) side from your charging vehicle to the negative side of the 6V battery that goes to ground in the trailer. You will need to connect the (+) side from the charging vehicle to the positive side of the other 6V battery.
