Imagine XLE 21BHE Lithium battery conversion

Apparently on that model you are correct, the whole Power Control Center needs to be replaced, I have never seen or heard of that before. Usually, the Converter is replaceable inside the Power Control Center.

Here is a response on e-Trailer that addresses your unit. By-the-way, the answer also includes the Progressive Dynamics Power Control Center with Lithium charging you will need for your unit.

Ok thanks. I know I've tried to explain that before and others have said the same - that you don't have to replace the complete panel, but I think they just don't understand that there is a type of panel where it is integrated and cannot be separated. I was hoping you really found a solution to that. Thanks for clarifying.

Replacing the Converter is a fairly simple and routine operation. Maybe you could find a Mobile RV technician that could perform the operation much sooner.

My dealership quoted me a price of $500 to swap out lead acid batteries with lithium and swap out converter with the PD one. Seems pricey to me. Does anyone know what labor hours would be for swap of battery to lithium and hours for converter swap? They did not ask me any specifics of the converter.

I assume that is strictly a labor price and not parts. You should clarify whether they are quoting to replace just the converter, or the entire power panel. If just the converter, confirm that this is possible given that your converter/charger is integrated into your WF8735P which requires replacement of the entire panel - see manufacturers website. If they are quoting for replacement of the panel, then $500 doesn't seem so out of line (although it still is not that difficult to do if you are comfortable with electrical wiring). Swapping the batteries of course is negligible from a labor standpoint.

Yep, that'll do it. If you're not comfortable with doing it yourself, then spend the $500 and don't fret it. Should be a nice setup when it's all done!

TT hunting,

Any update on your install? I am looking at the same setup in our 2022 22RBE. We have this:

A Furrion 25 AMP charge controller – part number FSCC30PW-BL stock from the factory.

165 Watt Furrion solar panel stock from the factory

Converter is a WFCO 30 AMP AC / 35 AMP DC part number WF-8735-PB-GE stock from the factory.

I just purchased a Battle Born lithium battery.

Did you change out the converter to get the full charging ability for your battery? If so, what did you change to?
