Thanks for the information Annamarie. To upgrade the converter in your WF-8955PEC to work with lithium batteries, you'll need the Progressive Dynamics Replacement Section for AC/DC Power Distribution Panel item # PD4655V.
The Progressive Dynamics item # PD4655V is a direct replacement for your converter section. It's rated for 55 amps as well so you won't to upgrade your wiring. It has a integrated Charge Wizard that will monitor your Winnebago'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.
What year and model is your Winnebago?
