Replacement Lithium Compatible Converter Charger for a WFCO model WF-9855

Question:

I have a 2021 Grand Design Reflection 337RLS. I have replaced the lead acid batteries with lithium batteries. I need to replace the converter. Currently there is a WFCO model WF-9855. What is the correct replacement for the lithium batteries?

Hey Craig! I have a couple options for you. I have talked to Progressive Dynamics in the past with this exact question and while I have a solution for you there is no replacement convertor that will allow you to upgrade to lithium batteries.

The best way to upgrade your WFCO model WF-8955 power center is a new converter and panel that would be compatible with lithium batteries. You will want the Progressive Dynamics RV Power Control Center item # PD4560K18LS8. This power center can switch between lead acid and lithium batteries and will work with the lithium batteries like item # GP99QR.

If you do not want to upgrade your entire panel you can use the Progressive Dynamics 9300 Series RV Converter Charger item # PD79RR to just replace the converter. It won't fit in the panel and you will need to run a separate 12v line with a new breaker. It measures 8" long x 9" wide x 3-5/8" deep.

If you have any additional questions feel free to throw them into the comment box below.
