Which is the better battery configiration
I am trying to learn more about 6 volts batteries versus 12 volts. I know the 6 volts can be drained further and recharged more (better lifetime). At least that is what I think is true. But it seems...

Properly set up is not possible unless you wish to buy a special purpose alternator. Or add a diode type device to the existing alternator.
The computer in the engine "looks" at the starter battery voltage. When the starter battery has recovered--charging is scaled back. Once that happens there is little or no charging of the house bank.
A dc to DC takes the incoming voltage and boosts it to an acceptable voltage for charging the house bank.
My dc to DC charger does a maximum of 20 amps. That works out to less than 5 amps per battery.
Because I have a larger than usual bank, I chose to set the output voltage of the dc to DC at 14.7 volts. Don't do this unless you have researched what the ideal charging voltage is for the house bank.
