12v to 6v review?

Currently have 2-12v 7ear old batteries that appear to be getting weak. Am thinking of replacing with 2-6v GC batteries (or maybe 4).
Anyone have experience or real world review of moving to the 6’s?

FWIW - I understand the wiring process, have solar, battery monitor, etc etc. Just curious of the pros/cons between the two systems if anyone made the move.

    My next battery will be lithium.

    Mine too probably just not in the cards right now. Nothing against them, just a lot of $$. I also drive a GMC not a Lamborghini for the same reason. Lol.

  • IDK if it's still true but I was always told by battery distributors forklift techs etc. that there's no TRUE 12v deep cycle batteries because the plates aren't as think as real 6v deep cycle batteries. I had 1 - 12v group 27 in my first RV and I added another one. Later on, I talked to Hensley Battery in Denver and they told me a T105 would have more capacity than even a group 27 12v.
    It looks like GC2's are still the rage and the best bang! Craig
  • Or don't waste your time, since you arent' really into researching it anyway.
    Pros - everything
    Cons - Nothing, except you cant pull one to run your trolling motor or jump start your car.
