Anyone have any thoughts before I plug in and potentially overcharge my new batteries?

I have the same LION batteries. Their headquarters is here and I talked to the factory rep at an RV show and said that the progressive dynamics in my 3820fk won't fully charge the LIONS but it wouldn't hurt them. However, Progressive Dynamics makes a replacement converter charger for lithiums that I plan to get. For now, I only use the lithiums with a portable solar panel for off-grid. I still have the flooded golf cart batteries for on-grid. Kind of a hokey setup until I update the converter/charger.
