converter/battery charger Q?

'86 prowler lynx 30ft TT.

The converter puts out 13.8v constant to the battery and cooks it.

Is there a unit made I can wire in between the converter and the battery such as a 3 stage charger that would be able to regulate the power from the 13.8v (input) to the battery as needed?

The converter works just fine as designed. With 30amp shore power hooked up,everything operates normally.

Right now I have the wire from the converter dis-connected from the battery post. New Deep cycle battery installed.

I operate mostly on shore power but in the event of a power loss I wish to maintain my 12v system.

Thanks RK

Never have I seen such a beast, but I would also have an application for one if it existed. One of the solar charging regulators might work if you never dry camp. They also regulate to a single voltage, but can maybe set down to not hurt the house bank. We are chronic dry campers, so I am very fond of the multi-stage smart converter/chargers.

Thanks MattC
I have purchased a small solar powered charger and separate controller from battery tender. I haven't connected it as of yet. It may be my only answer. My TT sits at our hunting lease year round and we are there about once a month so shore power wouldn't keep it charged anyway I don't think. We do-not leave power on when we are gone.

I don't want to spend any additional money because I already have replaced the water heater, the AC unit, and replaced the entire awning due to rain bending it in half arms and all one night. (the materiel had a hole in the multi layers on top and filled up like a big pillow and destroyed it).

So I was hoping to avoid buying a new converter/charger.

I agree with you on the Solar Controller but ... I'm not sure the converter output voltage is high enough.

To the Original Poster

What converter DO YOU HAVE NOW and can you replace the electronics with a Progressive Dynamics 4600 series? The PD Intella power wizard controlled are the best there is for flooded wet cell charging.. Since I replaced batteries last year I check them often for fluid level (It is not water though that is what you add) so far (About 18 Months) I've not added.

Converter is PDI 9180+wizard Batteries Deca G-20s (230 amp hours) Very happy with it. The 4600 line should work exactly the same as the one I have.. Choose a size based on your batteries. (roughly 30 percent of the 20 hour Amp Hour rating).
Home is where I park it!

Years ago I used to have a 1985 prowler and had the same issue. This trailer had an Iota brand converter charger and had a port for a module that turned into a 3stage smart charger. I believe that it costed me $15. This solved the constant boiling problem

Hey! I havent been here lately but thanks for the responses!!!

I have no idea of the brand. Its about the size of a tall shoebox. Metal grey in color. I have looked with a strong light and mirror. No part numbers are visible on the outside. It sits in the aft most compartment on the left side. (30ft TT).
It has a red, blue,and white wires coming out of it. The blue and white wires immeadiately go into the camper. The red wire is routed down thru the floor and runs outside under the left side to the tongue/battery.Its the one carrying the 13.8v and is dis-connected.

Thats all the info I have at the moment. Still having the same problem.

I had the problem in my 97 holiday rambler travel trailer and bought the precision dynamics 3 stage. Cut the old power panel in half horizontally to keep the AC breakers. It works great and the 2 batteries are 2 years old. Discarded the dc converter. No more burnt up batteries.
