battery usage
I've been having some electrical problems, when operating my small tt on ac, without the 12 volt battery. An rv tech said that you must/should hook up your battery, even though you are only connected to ac. Opinions?

Welcome to iRV2, hatchhanlon!
A lot of converters require batteries to filter the output, and it sounds like you have one like that. Unfortunately, unless you want to replace your converter with one of the newer types you'll need a battery  .

Please drop by and see all the stuff in the RV Systems & Appliances Forum. Batteries, charging systems, inverters et al are all discussed in that forum quite freely. Just post a question about your electrical concerns with your motorhome and you'll get a lot of feedback.

Welcome to iRV2.com. We are glad to have you join us here. I am sure you will enjoy the website and forums.
You should have a battery on the 12 volt system. Try it and you should see a difference on the AC problem. If not let us know.

Hi hatchhanlon,
The bottom line is there are systems in your RV that need 12 VDC to operate. This is true even if connected to 120 VAC. Each RV is different as to what these appliances are. If you are always connected to 120 VAC, maybe one 12 VDC battery will work for you. There are other battery options, it just depends on how much time you will spend not connected to 120 VAC.

Most converters require the use of a 12 volt battery. This will supply constant 12 volts to your system. Without the battery you run the risk of replacing the converter, whish can be costly. Be sure to use a deep cycle battery.
