You sure can Randy! You'll need the Progressive Dynamics Replacement Section item # PD4655V. This is a 55 amp converter charger that is compatible with both lithium and lead acid batteries. It is designed as a factory replacement for the following converters and will fit into the power center:
55-amp Parallax/Magnetek model 6355, WFCO 8955, or Parallax RV power centers models 7355, 7155, and 8355
What model power center do you have in your RV?

The Progressive Dynamics PD4655V has been working for my Thor Chateau 28Z with 2 LiTime 100AH batteries perfectly. Install was easy. Definitely worth the upgrade.

I changed out my old converter/changer to this one on my 2005 Winnabego Minnie and couldn't be happier. My last one was only 45amp and the 55 gave me more power and also has multi stage charging and a trickle change stage which works amazing. I ditched my Battery Tender I was using to keep the house batteries changred up and now letting Progressive Dynamics Replacement do it's thing. I have been using it now with no problems for over a 1 1/2 years and it's also works well with my Victron Solar controller.

Randy, I installed the same converter and bought it from etrailer.com. I installed it in a 2021 Thor Fourwinds C class. It was easy and works well with my Epoch lithium batteries. No issues and installation was simple. They sell them and it is worth it.
