Hey Jim, we have the # PM94VR that will work great for your 300 ah lithium battery. This is 55 amp like you are wanting, has a lithium profile like you'll need and it doesn't rely on auto-detect to determine battery type so it will for sure charge your battery without any guesswork. What camper fifth wheel camper do you have?
