No reason to even consider NOT using two 6's.
Use two 6's!
As stated, you obviously lack research ability as this has been discussed and a search will turn up lots of answers, most all in favor of the 6's.
GC batts (any true deep cycle batt), never, never, never Marine batteries unless you are on a boat using one battery for engine and trolling.
You could get three 4 volt too.
Thank you for your feedback... Interesting how you completely missed answering my question regarding "any real world reviews" and my comments about "I already understand the concept" to respond with spouted data from the 1000's of posts that me and you have both already read. Then took the time to call me out for MY lack of research to a topic that is not only asking for but also named "review" in the subject line.
I truly hope in the future you can see the forest for the trees and that someone somewhere out there gives you a nice big warm bear hug to make you feel better.
I will look into the 4v battery suggestion... LOL.
