Try again. Yipes! :( One foot of #4 one way (1 ft pos and 1 ft neg) is more like it.
With four 6s you can run that 100a draw until the batts are about 50% down before they alarm off at 11v loaded. With two 6s, you can run that until they are about 75% SOC (25% down) before the 11v alarm goes off.
12v batts will do a little better before hitting 11v but the secret is AGMs. You can do down to 50% with two AGMs before hitting 11v alarm off. So if you have limited battery space or weight to two batts, and want to run a big invert load, get AGMs.
You know, I was at work when I did that search so when I say cursory. It's just that! I just took another look and looks like a lot of info is taken into account namely temperature. #6 wasn't even listed for a 100 amp run, anywhere.
