adding batteries

[my80chevette]

I have a late 70s three wheeled ezgo and have just been playing around with it. I am using 3 12volt bats and would like to add 3 more. How should I wire these in so as to keep the total voltage at 36? Thanks for any help you can offer!!

For each battery you have now hook another one up to each + & - post. You will have 36 volts as far as the cart wiring is concerned but it will be twice the amount. You will have two 12 volt batteries connected together.
