How do I connect three 12-volt batteries to get 36 volts?
Lets number the batteries to simplify... B1-B2 andB3. Connect a cable from B1,negative, to B2 positive. B2 negative to B3 positive. Now you will have 36 volts by using B1 Positive and B3 negative. Also you can get the same voltage using 6 six volt batteries, the result will be a longer lasting charge, aka, drive further. Hope this helped.
