Wiring four 6V Batteries--is this the best method?
Increasing the battery bank from a pair of 6v T-105's to four. Below is one possible way (maybe the only way?) to accomplish it: Is this the only (and best) way to connect them?

Yes, make it so.
Note: If you're adding two new batts in with two older ones, keep the two older ones together as a 12v string, and add the two new batts as another 12v string, and then parallel them into a single bank.
Try to get their resting (open circuit) voltages as close as possible before wiring them together. And be sure to use heavy cabling; at least 4ga, but 2ga is even better. And try to find heavy duty tinned copper terminal rings.
