Golf Cart Battery Voltage Basics
Voltage Explained
Battery voltage shows how much electrical force a golf cart uses to move. Each battery in a golf cart has a certain number of holes, and each hole equals 2 volts. People can find the total voltage by following these steps:
Locate the battery compartment under the seat.
Count the number of holes on one battery.
Multiply the number of holes by 2 to get the voltage of one battery.
Count the total number of batteries in the cart.
Multiply the voltage of one battery by the total number of batteries to find the system voltage.
For example:
A cart with 6 batteries, each with 3 holes, has a 36-volt system.
A cart with 6 batteries, each with 4 holes, has a 48-volt system.
A cart with 4 batteries, each with 6 holes, also has a 48-volt system.
Golf cart battery voltage helps owners know how much power their cart can use.
