Depending on which remote panel you have you can program it for the correct type and amp hours of the battery bank. If the remote has red lights on it to show status, there are dip switches on the back to set it up. If it has the green lights, then it can be set it up on the front. You should be able to find the manuals online on how to program.

Red tractor I just read the manual and starting to understand what Brent is talking about on my panel the indicator lights are red there's no green lights on it. tomorrow I shell look at the settings on the back #2 and #3 what they are set at and try this equalizer the batteries where change at the time I purchased this motor home by the dealer, and maybe this has been my problem all a long

Go to the inverter/charger itself. If you have a battery temp probe, there will be a telephone-like jack/connection.

Just unplug it.

See that voltage are compared with it plugged in.

Will do first thing in morning I believe that I seen it there when I was in that compartment

Good morning Brentt this morning I followed the wire From the batteries to a temperature control module in the electrical panel in the compartment from there it goes to the inverter (Freedom 25) and plugs in with a telephone wire then there another telephone wire goes from the inverter to a silver box on the roof of the compartment marked HWH corporation I think this is the leveling system
Do you think this red light on the temperature control is a warning light that there is a problem I read the manual and trying to understand it but I don't see any thing about this temperature control
Here are pictures if you can make sense of this problem or point me in the direction I need to go
Last night I left the coach unplugged from shore power this morning it read 12.3 volts I plugged it in to shore power it climbed to 14.4 volt then after ten minutes it settled back down to 13.8 volts everything works perfectly just the batteries boil you don't smell them or see them boiling just the top of the batteries are wet with water bad enough that it runs down the side. Here a picture of the batteries this is the only information I can find on them they are not marked deep cell the battery compartment is very will vent someone was asking about this which has nothing to do with over charging but it is safety it looks like I'm the only one that has had a problem like this?

I don't know anything about Freedom inverter but I think you should get the float voltage below
13.5.

Yup. Interested to see what voltage is after verifying programming and disconnecting the battery temperature sense wire.

The only manual I was able to easily find is the manual for the model 458. The voltage chart is disturbing to me because the voltages are too high for continuous day in, day out, use.

14.4V should be limited to four hours or so before switching down to 13.6V The 13.6 volts can continue for the next twenty-four hours or so before switching down to 13.2V. The 13.2V is the Float voltage and is used to keep the battery from self discharging through internal chemical reactions.

But, a defective signal from the battery temp sensor can easily cause over-charging. Absolutely, if the inverter/charger receives a signal from the battery temp sensor that it is below freezing, it will cause these exact symptoms.

That is why disconnect it, reverify programming perimeters and see what it does.

And, when looking at the programing (with remote temp sensor disconnected) program it for hot/warm temps. That will lower voltage as compared with cold temp programming.

According to the manual for the Freedom 458-20 merely disconnecting the temperature sensor will cause the inverter-charger to revert to the 70s.

Update on my boiling problem
I removed the Remote Control Panel from the wall to check the settings on the Dip switches it was set wrong they where set for Cool Gel cell below 80 Fahrenheit I have wet cell Batteries so I changed the settings to wet cell above 80 Fahrenheit and the battery voltage went from 13.9 volts to 13.7 volts
Next I disconnected the Temperature control sensor. the battery voltage went from 13.7 volts to 13.1 so I found that low so I change Dip switch setting to wet cell below 80 Fahrenheit and the voltage went from 13.1 volts to 13.5 volts which I believe it's normal
I am wondering the garage that the coach is in is only heated to about 45 degrees so maybe the temperature control sensor is working correctly and that the voltage of 13.7 volts is correct for that temperature or is it OK to operate the inverter with out this sensor hook up the voltage is dead on.

Go back to the setting that gave you 13.2V for the time being and see if your batteries become discharged.
You won't hurt the Freedom 25 by running with the temperature sensor disconnected.

So took the advice of the forum and took out a volt meter and checked the battery voltage at the batteries. Start batteries 13.9 and the house batteries 13.6. The magnum says they are in float with 0a usage...
Is there an adjustment that I am missing on my magnum 2812 that requires setting??

What is ambient temperature? If cold, that is fine, if warm that is too high.

Assume you have gone through the programming of your inverter/charger.

Room temperature is at 40 degrees that what I keep the building at I went over the Dip switch program I only set the Battery Type wet cell cool

1st setting is Equalize OFF
2nd setting is battery cool wet cell OFF
3rd setting is battery cool wet cell OFF
4th setting is Auto Charge enable:charge on when AC connected OFF
5th setting is Idle sensitivity OFF
6th setting is Idle sensitivity OFF
7th setting is power sharing OFF
8th setting is power sharing on
The only setting on position is the 8th setting below is a picture of the Dip switch program please advise if any of these settings should be change I believe these are factory settings can see someone playing around with then since you have to remove the control panel from the wall I only change the battery settings

Peter the Magnum can be adjusted to what ever you want. The tech guys are really helpful and
here is the number 1 800 553 6418. Why is your start batteries higher, do you have a separate charger
for your start batteries. I have been having trouble getting my float to 13.8 as it has been too high
and they have been working with me and the last guy said it may need to reboot it. Luckily for me
my batteries can handle the higher voltage

interesting topic came out of the house the other day, all I could smell was rotton eggs, my older AGM battery was boiling, not sure why it had been operating with no real issues, hopefully get the lithium batteries in sooner than later, replaced the AGM with a cheap NAPA battery just to get by

Yes I have a battery minder charger on the start batteries. I have not had any issues(smells, boiling or the batteries have not been hot to touch) so I presume everything is ok. I am going to give the tech a call just to check..

To lower charge voltage, set temperature higher.

If plugged into anything but a 50 amp outlet, use power share to limit amps of 120 VAC to be used for charging to 5. That still provides around 50 amps to the batteries, and leaves you amps to use for other things.

The only time you really need power share off/high setting is if you are running the generator to recharge the batteries. Under those conditions, max charge rate is a benefit.

Still scary having vented battery's in a closed compartment. You are endangering yourself

With the proper applied voltages there will be minimal to no out-gassing.
I prefer to save the fear for things that are truly scary.
Wait. I lied.
I plan for the worst and rely on training to react properly. So far it's worked.

Cape Bretoner? Set your DIP switches for the Warm Wet Battery and leave the temperature probe unplugged.

FWIW Can you, from the control panel manually select 14.4V aka Rapid or Bulk charging? If the answer is yes and you want to warm the batteries when the temperature is -30C to, I don't know, turn your main engine for starting? That'll do the job.
