Choice of Batteries - Which Would You Choose?
Need expert advise from those that know batteries best. I have an 05 PW Excel that has room for just one 12v house battery in the outside compartment. It's a wet cell, and just as soon get away from t...

Is there really any advantage to 6v AGM over 12v AGM?
Flooded 6v are more robust than most flooded 12v but I doubt there is much advantage to 6v AGM.
An outstanding question in your first sentence that I've asked a few times and never received an answer to.
With respect to the "thicker plate" argument when comparing 6V flooded deep cycle batteries to (true) 12V flooded deep cycle batteries:
For batteries of equivalent capacity and cycle life, 6V cells have to carry twice the current of 12V cells - and since plate destruction/erosion over time has a lot to do (but I don't know how much) with amount of current flow over time - 6V battery plates had better be thicker than 12V plates in order to last as long as the 12V plates. For equivalent batteries, I suspect that quality 6V deep cycle plates should be about twice as thick as quality 12V deep cycle plates.
All IMHO, of course.
