Hey Dan, actually the correct replacement for your Intertek 8355 is the Progressive Dynamics Replacement Section for AC/DC Power Distribution Panel # PD4655V.
This replacement converter section is compatible with Lithium batteries along with flooded lead acid, AGM and Gel, and has an integrated charge wizard which monitors your RV's batteries and will automatically begin charging when needed.
If there is anything else I can help you with, please feel free to drop a comment and let me know!
