Converter starts/runs for a few seconds then stops

Is it because it’s cold here in the frozen Canadian climate?
It’s a WFCO 55 amp.

I would look at the 60 amp Boondocker.

This should meet the 14.6 volt charging of the battery and for lithium it has a very short absorption time.

If I have to replace the converter is there a converter that is compatible with wet as well as Lithium?
And is there any reason to go higher in amperage?

This works with any battery spec, voltage adjustable, perfect for LFP.

60 amps is good for a 100AH LFP above 41F. From freezing to 41F you need a lower amp charger like 15 amps so use a regular car battery charger or whatever till the battery warms up.

It’s a deck mount.

Is the WFCO-55 deck mount or the slide in mounted in the lower section of the electric panel?
I would stay about same size unless you plan to pull new wire for the entire battery charging loop.

If they freeze it's all over. Are you home? Take them out of the coach.

So I put my smart charger on them to bring them back up.
Plus thetrailer has been plugged for a couple weeks.

Thanks for the reply Roger.
I checked for voltage at the batteries and they tested 11.5. So it would seem it’s not charging.

Is it the converter that starts and stops or the cooling fan in the converter? The cooling fan is supposed to start and stop as needed to cool the converter. On cold days it will run very little as compared to when it is really working to keep the converter cool.
