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.

Hey Craig, how did the Progressive Dynamics converter work out with your lithium batteries in the Reflection? Knowing how that setup performed could really help others planning a similar upgrade.
