Question:

I have 2 six volt deep cycles wired in series for my solar and want to know if I can add a 12 volt to the group ? Thanks

To add a 12 volt battery to the two 6 volts you already have in series you will need to connect the negative side of the first 6 volt to the negative of the 12 volt. Then connect the positive of the second 6 volt to the positive of the 12 volt. The positive of the 12 volt will connect to your 12 volt circuit and the negative will then be grounded.

See the diagram I've attached.
