Can You Use The Progressive Dynamics 4655 To Charge Lithium Batteries?

Published 02/16/2022

Question:

I am preparing a presentation for the International Airstream Club on Batteries, Chargers, converters, and converter upgrades yours For over 8 years I have had a Lithium battery installed in my Moto Guzzi motorcycle without any modifications to the charging circuit and it is still working fine. I recently installed a PD4655 upgrade in my Airstream and I wonder what would happen if I switched to Lithium batteries as I am sure that question will come up.

I took a look at the replacement Converter for Parallax/Magnetek or WFCO RV Power Centers # PD4655V that you mention, and unfortunately it will not work with lithium batteries, and should only be used on flooded lead acid, AGM, and gel batteries.
