I have several 12 volt batteries installed in parallel for house power; I am looking to replace them soon. I will be going to some version of 6 volt deep cycle battery. Please note that in this example it is a perfect world like on TV in the town of perfect. My question is what happens to the amp hours if the batteries are connected in parallel for 12 volt verses batteries tied in series parallel? In my example I will say that there are 5 group 28 12 volts at 100 amp hours that equals 500 amp hours. In a separate bus there are 4 6 volt batteries at 200 amp hours each which is 800 amp hours tied in series parallel to make 2 12 volt cells. Is this correct or does the to cells equal 400 amp hours?

I love my ugly bus

Hi John,
With the 6 volt setup you would have 400 amps at 12 volts. In series the voltage doubles and the amps are divided in half.
Good Luck

400 is correct.
Voltage/amp hours are accumulative in one discipline only, depending on if they are wired series, or parallel.
I like to use the example of this using a 10 battery array. If you wire 10, 12 volt, 100 amp hour batts in series you end up with 120 volts but with only 100 amp hours.
Wire the same 10 batts parallel and you end up with the 12 volts but at 1000 amp hours.
