Converter starts/runs for a few seconds then stops

It’s a WFCO 55 amp.

How do you know it stops? Most modern converters are rather silent. about he only thing that makes noise is the thermostatically Controlled fan. It will generally start when you first plug in (part of the power on self test) but then shut down cause... in your own words IT IS COLD.

A volt meter will tell you if the converter is converting... The basic rule is Not working = <13<13 equals working But depending on many things it might take a bit to come up.

(That's less than 13 not working actually 12.6 or less) and greater (13.6 is not uncommon) = working. more than 14 = bulk mode

What’s the difference there between the two 60 amp ones. The one says “hardwired”.
That’s not explained.
Is it compatible with lead acid as well?

Hardwired would be connected to a J-Box with romex. Not hard wired would have a 5-15 plug to go into a standard wall outlet.

Yes lead-acid is fine. I would probably get a Progressive dynamics for lead-acid as they have a longer absorption time. The smaller Boondocker (45 amp) would be slightly better with lead-acid as it will shift to normal (13.6v) at a higher state of charge.

You want the other 60 that has a plug in 120v cable , not the hardwire version if you get the Boondocker. He has two versions see his lettering explanation for the models. The Boondocker is a PowerMax, re-labelled. BoatandRV seems to be a better price and free shipping, but not to Canada sadly.

If you can get them to send it via post office it can save a fee compared with the other couriers AFAIK.

Yes, it works with any type of battery. You have to do the adjustments to the voltage for that mode, or you can just leave it in automatic three-stage for your Wets.

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.
