Following the wires is harder than understanding the concept.
2 6V batteries hooked up with the + of one connected to the - of the other will give you a 12V battery.
If you have multiple sets like this you simply link all the FREE + terminals together and all the FREE - terminals together. This will give you a 12V battery bank.
To know the size of the bank multiply the number of 2 battery strings times the size of one 6V battery.
If you have 2 6V 100AH batteries in series this string will give you a 100AH.
If you add 2 strings together in parallel you will have a 200AH battery bank.
Of course in the real world of batteries you really don't have the ability to use all 100AH without doing major damage to your batteries.
