On my boat, I have 2 six volt batteries wyred to make 12 volts, and 1 12 volt starting battery. The smart unit that the alternator provides power to, figures out which unit needs charging. It recognizes the 2 six volts, as one 12 volt, and the starting battery as one unit.The two 6 volt batteries should be the same type and age.
The shore power, 110 volts, also has a smart unit that does the same thing. Blue Sea makes these units.
But for your golf cart, I think it will depend on what type of fancy unit is in the charging circuit you have, and whether they are all wyred as 12 volts.
A search of Blue Sea charging distribution units should yield some results.
