Question:
Im looking to replace a WFCO wf9855AD with a lithium compatible progressive dynamics floor mount. Would I want the PD9630? WFCO will not auto detect lithium batteries. Thank you!

Hey Ron. To replace your WFCO WF-9855AD and it is a 55 amp charger, you'll want the Progressive Dynamics 9300 Series RV Converter Charger item # PD79RR.
The Progressive Dynamics item # PD79RR is rated at 60 amps and is compatible with flooded lead acid, AGM, and LiFePO4 batteries. It doesn't switch automatically. However, once you press the mode button and turn the LED light blue it will stay on a lithium charging profile.
What kind of trailer or RV do you have?
