Thanks for the link - I've bookmarked it. I will definitely consider the 2V scenario as well. I was heavily favoring the 6x6V setup because of in case one of them fail and still having 12V power but I also ready from somewhere else that batteries simply don't fail often enough to consider this a scenario, as long as it is maintained correctly. So perhaps 2V path is ok as well.

Hi Acei,
Be aware that the taller the battery the more important it is to use a charging routine that helps prevent stratification.
For a bank of three 12 volt batteries (6 x 2 = 12) there is only one method to wire them in a balanced manner. Only method #3 on this page will work: correctly interconnecting multiple twelve volt batteries
Others may say it doesn't matter--but unless there is a compelling reason to not optimize charging and discharging why not do it the best possible way?
In your shoes I'd still consider two volt jars such as the Trojan L16RE-2V fourth one down on the chart
