I realize that my post was a bit long, but I explained in detail that since the batteries are not the same, simply saying "parallel is less resistance than series" doesn't work. Yes, the combination of two 12V batteries in parallel have less internal resistance than one identical 12V battery by itself, or two of them in series, but that's not anything like two 6V batteries in series. You can use the formulas on that web page if you like... just use four times as much resistance to represent a 12V battery as you use to represent a 6V battery.
