Expert Reply:

Progressive dynamics doesn't offer a Lithium-Ion compatible converter only that would replace the one used in your WF-8725, so you'd need to replace the entire power center panel using part # PD4135K which is compatible with Li, lead acid, AGM, and gel batteries. The converter has a 35A output which would be a 10A increase over your existing converter.

I've linked to install and demonstration videos that you might find helpful.
