Do I need the battery?

Hi,
Bought a used 1995 Solaris T-2251 and there is no battery on the tongue. Matter of fact there is no battery anywhere. There is a breakaway switch that is broken so I want to replace it.
I know they have breakaway and battery kits that I could buy and hook up so that I at least have a functioning breakaway switch. I think in this scenario the chargeable battery is small and just to power the brakes if the switch pops.
If I goes this route and don't put a deep cycle battery in for 12v trailer power, is there anything that will not work in the trailer when I'm hooked up to 110 at a campground?

Are there any other threads on how to wire up a breakaway switch and or deep cycle battery to my model Solaris?
My battery wires look they are all there, just capped off.

Thanks in advance.

Al

Just do a deep cycle battery.

Your converter system in the trailer is designed to have a battery. Without it, the only power capacity you have for the 12V stuff is from the charging circuit in the converter, which is essentially a trickle charger. You could also have somewhat inconsistent power from it, causing problems with things in the trailer. I heard of someone recently who started out with exactly what you propose. They couldn't figure out why they kept blowing light bulbs inside. Turns out they were getting too much electricity because ever since adding a battery, they haven't had a problem.

You have to remember, most of the systems in the trailer are designed for 12V. The exceptions are the A/C, microwave, and then the electric mode on your refrigerator, which require 120 from being plugged in. All the lights, radio if you have one, furnace blower/ignition, water pump, and probably a few things I'm forgetting all run off of 12V. They continue to run off 12V even at camp, and the converter simply keeps the battery charged as needed from you plugging the trailer in. Really, you could live at camp if you never plugged in and just charged the battery with a typical battery charger, it's just you wouldn't have those three 110 things.

Remember too, if you skip a battery, you can't run your refrigerator while on the road.

Running these trailers without a battery on short term basis (for loading it in the driveway, etc.) isn't a problem, I do it sometimes, but it should be kept at minimum.

If money is tight and deep cycle isn't in the budget right now. Check out an auto junk yard. They have plenty of regular batteries sitting around. Cheap

We extended the "Midwest Meet and Greet" weekend (by the way, a really great time) several days and upon our return realized the converter/charger on our Que had failed and in a couple of days the battery was dead. When Al asks what other things will not work on 110v, is it possible the refrigerator won't? I've been on shore power since returning and not only does the battery not charge but the refrigerator doesn't work. Or maybe I have another issue?

12 volts powers the refrigerator circuit board.

Thanks, Jim. I feel better that possibly I have only the converter/charger to deal with.

If you run the fridge on 12 volts and not propane you most likely won't get 24 hours out of the battery the heaters draw a load of current. Some converters will not work with out a battery and those that will still should have a battery as a buffer it also will power your emergency trailer brakes and any boards requiring 12 volts.
