Lithium batteries

Hello. New here and first post. I have a question.

I have a Jayfeather sport 165. I need a new battery but am unsure what type. Agm or Lithium. If Lithium, will my trailer handle it or do I need to make a bunch of alterations? Thanks and looking forward to your suggestions.

First step is what converter do you have? That's the most expensive component that potentially needs to be upgraded.

How much off grid, boondocking, dry camping do you do? If you are mostly hooked up to utilities the added cost of lithium isn't necessary.

Do you need AC? microwave? Etc. What are you every demands when not hooked up site shore power?

As noted above we need a lot more info such as make, model and year of your RV. What your power needs and camping type is. What your converter is to help you find if a lithium can be fully charged, etc.

I would suggest going to and look for "learn" and beginner solar. Not that you need or want solar but they give some excellent info on the basics of RV systems.

I like lithium. No worries about keeping above 50% or ruining the lead battery. Lighter weight for my old arms to pick up. Longer life by several years, etc. A bit more money up front but a big savings in the long run.
PS. Your converter will charge the lithium up to about 80% but that is still way more than a typical Group 24 deep discharge battery with the advantages above.

Thanks for the replies guys. Got it figured out. Yes I can use lithium with an inexpensive smart controller. Mainly looking at weight difference with lithium.
