Hello Victor, thanks for reaching out. The Progressive Dynamics 9300 Series RV Converter Charger #PD79RR will work great for replacing your WFCO WF-9855 converter. We recommend this model as a replacement quite frequently in fact, since it has the…

Hey Michael, It sounds like your original pin box on your Jayco was a Lippert 1621 or 1621HD, the MORryde upgraded pin box for that is the MORryde Cushioned 5th Wheel Pin Box part #MR84VR which has the MORryde RPB72-1621HD part number. The Gen-Y…

Hey William, you can upgrade to a 35 amp panel/converter like with the WFCO part #WF96FR (we don't have any 30 amp options) but you should note that when doing this you have to also upgrade all of the wiring that runs to and from the converter as…

Hey Steven! The Cummins Onan EC-AGS+ #CM96MR will still work with your lithium batteries. The limitation is only the low-voltage auto-start feature. Since lithium batteries maintain a fairly constant voltage while discharging, the AGS can't…

I have a solution for you because as you know what you have now cannot charge Lithium batteries. You will need the Progressive Dynamics #PD4135K which is designed to replace your WF-8735P and is compatible with Lithium batteries. When this is…

Hey Ron, great question! The new PowerMax stand-alone converters like the 45A #PM34VR, 55A #PM94VR, 60A #PM44VR, and 100A #PM84VR give you three selectable charging modes so you’re not locked into one charging behavior. 3-stage mode factory default:…

Hey Rich, yes you can definitely use the PowerMax Wireless 50A RV Power Center and Distribution Panel #PM77VR in your cargo trailer setup. You'd run the AC input to this and you'd have DC power circuits for anything that's DC powered in…

Good question, Tyler. Yes - the WFCO RV converter power center #WF86FR 55A will recharge a battery bank faster than the #WF46FR 40A, especially during bulk charging. That said, the difference is most noticeable when: -You’re running dual batteries…

Hey Henry! Yes, the PowerMax AC to DC Converter #PM94VR is a great choice for your setup. The 55A output pairs well with your 900W generator, so you’ll get fast charging without overloading it. This will give you lithium compatibility with efficient…

Hey Reno, welcome back! The current version of the Progressive Dynamics item #PD4045KA has a switch at the top left of the converter that you can see in the pictures below. If your item #PD4045KA isn't lithium compatible the Replacement Converter…

Hey Lars, I would go with a higher rated Progressive Dynamics converter like the #PD79RR which is rated for 60 amps because while your RV has 30 amp power that's on the AC power side of things and this converter takes that AC and converts it to…

Hi Trent! The WF-9865 you have now is not lithium compatible. I recommend replacing it with the WFCO Auto-Detect RV Converter Charger - Deck Mount - 12V - 65 Amp #WF98FR. This is the same 9865 you have now so it will be an easy swap. The only…
