If you have the WFCO convertor and you leave the RV plugged in 24/7 then you may have one or more battery cells with little or no water as the WFCO convertor does not have an intelligent trickle charger. You can check the water in the battery to see if that was the problem, but if that is it, you should replace the battery as it will have incurred some damage.

The answer is Yes, you could do that; i.e. remove/disconnect the converter, and use a battery charger to recharge the coach battery.

You will need to make sure you do not over charge (boil the battery) or under charge (run the battery low ) These will both kill your battery in a short time.

The converter not only keep the battery charged, but it actually supplies the 12 volts to your systems when your plugged into shore power or running on a generator.

Without the converter, your battery supplies power to the furnace, water heater, frig, lights, fans, etc.

I don't like large power fluctuation getting into electronic equipment, connecting disconnecting a battery charger will give these fluctuation. Also hydrogen gas will be developed when you deep cycle the battery, so use caution when connecting/disconnecting the battery charger (

Keep an eye on the fluid level in the battery (you should be doing this anyway, but more so if your deep cycling the battery.

My recommendation would be to replace the converter with a three or four stage unit. This solves all the problems.

The short answer is yes, you technically can delete the converter and use an external charger to keep re-charging the batteries. I would just upgrade the converter and be done with it.

As others have stated, you could do what you discussed.. Many members do the exact same thing when their converter dies while out on a camping trip.

However, I don't know if I have heard of anyone doing it for except in the very short term, until they could get a replacement converter. I also don't know of what the long term implications would do to the battery (or anything else) depending on what kind of charger you had.

If it were mine, I would replace the converter with one that others have pointed out and be done with it......but that's just my opinion.

I think you have to remember, I guess you can do what you want, but a person should only draw down there battery to 50% so how long would that take? The convertor takes out your battery for most part being it is giving out 12v power all the time. So if you turn on all your 12 volt items they all can run. As far as getting hot the fixtures. Well that is true but you can always go to LED bulbs. (less amp draw) I really don't see a savings by your way, you can get a 70 amp charger/converter for about 185.00. To buy a 4 stage automatic charger would cost alot more then that. Also by your way of wanting to do it your going to need to add a amp meter so you can monitor the state of the batteries. Those are not cheap either. I have never heard of a battery being low on water to smoke a convertor, but I surly do not know everything. I good place to start is to read living on 12 volts, that might help you...Good Luck no matter what you decide.

If you are never going to move, then using a "smart" charger on the batteries will work to keep your 12V power going and your battery(s) from overcharging. I would also change out all the incandescent hi-current (hot) lighting in your trailer to cool and efficient LED lighting. I purchased some replacement LED's off amazon, but also bought some from
They have a real helpful website.

Yes. You "can" physically disconnect it with ease, but if you're on shore power all the time what would be the advantage in doing that? There would be a little more wiring that would need to be done ($), you would still need to purchase a stand alone 4 stage "smart" charger ($), increase your battery bank capacity ($)...

You're basically just trading out a converter/charger with a straight charger.

It's entirely up to you of course. Heck.. my converter is physically disconnected. However.. I had a specific need to disconnect it... while normal CG type camping and 24/7 shore power available I can't imagine going to all that trouble and additional expense if I didn't have to.

Not sure that is simple, so humor me .
Everytime you go camping you must get charger out and an extention cord and plug it in and turn it on and every time you are done camping you must unplug charger and store it, wrap up cord and store it as well.
Please explain how that is simpler then just plugging in your camper and moving on to fun stuff?

Hallo . Mine is permanently disconnected. But you're right... under normal circumstances I wouldn't complicate matters without a good reason to do so.

If you decide to go that route you would also need to take into account the cost of increasing the capacity of your battery bank. That alone will put you over the cost of a new converter. A single 12v automotive battery would not be sufficient in type of setup.
