Hey Jeff, thanks for reaching out!

Yes, the Progressive Dynamics 4500 Series RV Converter w/ Charge Wizard # PD4560K18LS8 is compatible with lithium batteries. All you have to do is swap the jumper over to the "LI" side (see attached photo) in order for the charging profile to work with lithium.

Let me know if you have any other questions!

Hey Jeff, how did things go after switching the jumper to the LI side on your Progressive Dynamics converter? Did the lithium battery charge the way you expected? Your update could make it easier for the next person making the same upgrade.

Yes, after I made the proper connection the lithium battery charges now.
