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 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 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…
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 Thomas, thanks for reaching out. You will definitely want to stick with a 30 amp when replacing your old 30 amp unit. For that I recommend the following: - Progressive Dynamics 9300 Series RV Converter Charger - 12V - 30A #PD49RR There would be…
Hi Angelo; the PowerMax AC to DC Converter #PM94VR is more of a budget option but it doesn't mean it won't work well for your application. PowerMax converters are well made and ETL rated. You’ll just need to manually set the output voltage…
Hey David, welcome back! The big advantage you'll gain using a 65 amp item #WF98FR or 75 amp item #WF48FR converter charger over a 55 amp item #WF38FR would be to charge your batteries faster. You would also be able to power more 12V DC…
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…
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…
