Question:
Hello—I have a 2021 Airstream basecamp 16X, with factory supplied 24 series AGM battery’s, and a WFCO Model WF 8955PEC charger/converter. I am going to replace the AGM battery’s with group 24 lithium’s, and will need to change out the WFCO Model WF 8955PEC as it is not lithium compatible. I prefer Progressive Dynamics brand, and ask is there a PD model lithium capable, to replace the WFCO Model WF 8955PEC? Thank you

Yes there is Randy, and thanks for the information! To replace the converter section of your WF-8955PEC 55A power center, you'll need the Progressive Dynamics Replacement Converter for WFCO RV Power Centers item # PD4655V.
The Progressive Dynamics item # PD4655V measures 13-1/4" long x 8" deep x 5-3/8" wide. It has a integrated Charge Wizard that will monitor your Airstream's batteries and automatically begins charging. This 55 amp converter works with AGM and Lithium batteries so if you swap out the converter before upgrading the batteries it'll still work.

Hey Randy, how did the swap to the Progressive Dynamics converter go in your Airstream? Did the Charge Wizard work smoothly with your new lithium batteries? Your update could make it easier for others planning the same upgrade.
