My camper has a 55amp WFCO power center. I see a module on their website to change it over for using with LiFe04 batteries. I expect the battery monitoring system in the “lead acid replacement” type lithium batteries will protect them from the charging sources (WFCO / Zamp solar) going crazy and wrecking them.Has anyone got any experience using the WFCO lithium module?

Someone might happen along who has done that. But I wouldn't hold my breath. I wouldn't spend a dime to save a WFCO converter. I would replace it with a better unit.

Actually a knowledgeable friend of mine who has built their own rig that is all electric and solar/lithium powered says based on my rig’s electricity needs a conversion to lithium is a waste of money.

I have a brand new WRCO converter in my garage that I will giver anyone that wants to pay the postage. I installed a Progressive Dynamics unit and my installed DC volt meter shows the converter working properly by switching between the different charge rates. The WFCO just sat at 13.2 volts even when the batteries were run down. The TT was 3 months old when I did the upgrade.

Bob it sounds like you have a faulty WFCO that should have had a warranty claim made - mine 3 stage charges the wet batteries. I have 2 other rigs with PD power centres that are good units. They are 90 amp (I think) anyway they will make a Honda 2000 throttle up when they bulk charge flat batteries

I may change the whole unit out and add some more solar and stay with flooded or agm so as not to have to deal with protecting lithium batteries from cold.

More solar may be your best choice. Optimize your charge controller to compliment whatever batteries you choose.

I've left my WFCO converter in place, after years of planning to replace it with a PD. I went solar instead. The converter sits there switched off, and only gets turned on if a couple cloudy days come along and the genny comes out. Rare event, so no sense replacing the converter, but if it ever dies I certainly would not buy another WFCO.
Exactly what I did. It took a while but mine did finally completely die. Luckily I had just recently ordered a PD to replace it. I opted to get the higher voltage model from Best Converter to care for my T105s.

Are newer WFCOs still junk? The one in my 2018 Coachmen seems to do fine. I leave it plugged in all summer and not only does it keep it charged, it has yet to boil the battery.
Do you actually measure 14.4 volts charging when expected?
Would love to see some positive reports on WFCO.

I've never measured it. The TT is always on shore power, so the battery is never discharged. I just noted that it hasn't trashed the battery yet after three years, so it must not be trying to overcharge it. The battery never needs water, and I do check frequently.
