Replacement Converter for WFCO WF-8955PEC for Lithium Batteries

Question

Question:

I have a WFCO WF-8955PEC converter in my RV. I am switching to lithium batteries and need to change the converter. Will this fit into the same physical space as the WFCO main board assembly i.e. be a -in converter replacement? I was hoping it would fit into the WFCO chassisinch so I would only have to swap the converter and keep the AC breakers and DC fuse board.

To convert the WFCO WF-8955PEC to be lithium compatible you'd need the part # PD4655V and you'd be set. This fits in the panel without any modifications.

Is this an entirely different fuse panel and converter replacement? I have the same unit (8955PEC) in my toy hauler and would like to eventually upgrade to lithium, was hoping not to replace everything, just upgrade the wfco box, thanks in advance for any info you can provide

@Tim Its the lower section that basically replaces everything needed to allow it to charge lithium batteries.

The Progressive Dynamics Replacement Section #PD4655V does have a jumper to change the charging profile to lithium compatible. You'll simply need to move the black jumper over from the WIZ side to the LI side.
