Question:
Hi! Im double checking that the Replacement Converter Section for Progressive Dynamics Inteli-Power 4000 Series 45 Amp Power Centerinch will work with the WFCO WF8735/8740 in our 2012 Jayco Jayfeather x17z. If not, Id love a recommendation for the part to replace the WFCO converter that can charge two LiFePO4 batteries in parallel. Thank you kindly

Hey Jamie, thanks for the pics! I do have a recommendation for a how to replace your WFCO WF8735/8740 to be compatible with lithium batteries but the item # PD4045CSV, you referenced will not work and there is no way to just replace the converter.
I recommend the Progressive Dynamics 4000 Series Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel item # PD4045KA. This is going to completely replace your entire power center. It is rated for 45 amps just like your current one and is going to be compatible with lithium batteries.
If you have any additional questions, go ahead and click on the box that says Reply to Jerred H and I'll be happy to answer them.

Hey Jamie, how did the swap to the Progressive Dynamics 4000 Series Mini Converter go in your Jayfeather? Your update could make it easier for others looking to upgrade their WFCO units for lithium batteries.
