I currently have 4 12 volt Napa "deep cycle" marine/RV battries that I'm estimating at about 200 AH for all 4. The new arrangement should get me to around 800 AH.
Some bad math.. About the smallest 12 volt MARINE/deep cycle is the Group 24, and those run 70-75 AH each so you are looking at at least 300 AH now.
WHen you switch from one-piece 12 volt batteries to 2-piece 12 volt batteries ()
(6V)+(6V)=12V
You add voltage, not current
Your T-105's are what \215 AH, so two pair would be 430 AH.
Just so you know. (you do add the two pairs, but one each pair you only add voltage, not amp hours).
Beyond that correction I have no comment.. It is an upgrade, and also the fact that the T-105 is a True DEEP CYCLE, not a "MARINE" adds to the usable capacity I might add, also to the overall life of the batteries if properly cared for.
