If you will be adding a 12 volt battery to a bank of two 6 volt batteries wired in series you would simply attach the 12 volt battery in parallel to the two 6 volt batteries wired in series. Therefore, the positive wire lead on the 6 volt series battery bank will go to the positive terminal on the 12 volt battery and the negative wire lead on the 6 volt series battery bank will go to the negative terminal on the 12 volt battery.
In order to charge these batteries you would need a special type of battery charger that could not only charge multiple batteries at once but also different voltage batteries. For this, I recommend the NOCO Genius UltraSafe Battery Charger part # 329-G4 which can maintain up to 4 batteries ranging from 6 to 12 volts.
