Can I use 2 golf car batteries for a 12-volt system?
Yes. In order to use golf car batteries for a 12-volt system you would need to connect the 2 batteries in series. Connect the positive post of the first battery to the negative post of the second battery. Then connect the positive lead from the equipment being powered to the first battery’s positive post. Finally, connect the negative lead from the equipment being powered to the second battery’s negative post.
