I'm one of them. But that subject's been gone over before. As to maximum
cranking power from 2 six-volts, I don't think so. Wiring in series doubles
the voltage, not the amperage. Wiring in parallel (i.e., a 6-volt system
with 2 batteries) increases the amperage. Basically, I think that a
series-wired 12-volt system will have the cranking power of approximately
the average of the two batteries. I also think that a single 12-volt has
more cranking amps than the 2 sixes, as more development work has been
carried out on 12-volt batteries in the last 40 years than on 6-volt.
Any comments from the more electrical-minded?
