As in most electrical situations it is important that you know the maximum amp draw of the device being installed. In a series configuration the batteries are wired per the diagram below and the result would be a doubling of the voltage while the capacity remains the same.

6 volt to 12 volt battery wiring. To wire two 6 volt batteries in series to produce 12 volts you would connect the load to the positive terminal of battery 1. Wiring two 6 volt devices in series reduces the voltage from the battery by half so each device gets 6 volts. We have a chart for 12 volt 24 volt 36 volt 48 volt and 72 volt applications. This is known as a series connection. To connect batteries in a series use jumper wire to connect the negative terminal of the first battery to the positive terminal of the second battery. In our illustration we show two 6v batteries with 225ah wired together.
Wire size by gauge ampers draw and maximum feet of wire. Wiring batteries in a series. The result would be a battery bank that produces 12v and 225ah. Connecting 6 volt battery pairs in parallel wire the first pair of batteries a1 and a2 in series to output 12 volts at 225 amp hours wire the second pair of batteries b1 and b2 in series to output an additional 12 volts at 225 amp hours wire the two pairs together in parallel for an overall. A 6 volt wiring system and switches are more than enough to handle 12 volts. 6 volt agm battery has more life cycles.
This combines the voltage of the two batteries without increasing the capacity of the output which is measured in amps per hour. This is because its heavier because 6 volts has to carry more amperage than 12 volts. By charging 6 volt batteries in series with a 12 volt charger you allow your off grid electrical the true capacity it needs. I have produced a diagram showing the connections for you. It only needs to be about 12 inches long. For example these two 6 volt batteries joined in series now produce 12 volts but they still have a total capacity of 10 amps.
Connect the negative terminal of battery 1 to the positive terminal of battery 2. Dont worry calculating the wire size is made easy with the wire size guides below. Cut one strip of awg 18 gauge wire using a knife. Less volts means more amperage. Two 6 volt batteries can be wired together to create a 12 volt system for powering electrical devices. A 6v battery bank charging system will give you added amp hours and increased life cycles.
Ground the negative terminal of battery 2. Two 6 volt batteries in series vs one 12 volt life cycles. Wiring batteries in parallel. You use this wire to connect between the 12 volt battery and the 6 volt light bulb to switch the power to 6 volts. Changing to 12 volts cuts the amperage load approximately in half.
