Replacement Converter Charger for 50 Amp Trailer that is Lithium Battery Compatible  

Updated 06/30/2025 | Published 06/23/2025

Question:

I bought a lithium battery for my travel trailer without knowing I need a lithium power converter. How do I know which one to get? It is a 50 amp trailer. I am looking at the Progressive Dynamics 9300. 12V - 80A. Code:PD89RR Is that the correct one?

Hey David, yes the Progressive Dynamics 9300 part # PD89RR would be a great option to replace what you have and is lithium compatible. It's rated for 80 amps too so it will quickly charge your battery. What was the amp rating of your current charger?
