Parts Needed to Convert Parallax 7300 to Work with Lithium Batteries
Updated 02/03/2026 | Published 07/28/2024
Question:
Hopefully you guys can help me. I have a 2008 16ft airstream with a parallax 7300 converter. I want to replace it with a upgrade so that I can change over to a lithium battery system. What do you recommend for direct replacement that has the same features as the 7300. If you have a product would it be a plug and play . Hopefully no mods. Thank you for your time. Earl

Hey Earl, how did the swap to the 55-amp replacement converter go in your Airstream? Did it end up being a simple plug-and-play fit like you were hoping for? Your update could make it easier for the next person upgrading to a lithium setup.
