The basic principle behind a 48 volt golf cart battery system is fairly simple. When you wire six 8-volt batteries in series, you create a circuit with a total voltage of 48 volts. The first battery’s negative terminal connects to the second battery’s positive terminal, and so on until the sixth battery’s negative terminal connects back to the first battery’s positive terminal.

When this occurs, each battery functions as just one cell within a larger battery pack, and as current flows through the circuit, the combined voltage output powers the motor and accessories within your golf cart.

Wiring 48 volt golf cart batteries can seem daunting, but it isn’t too hard if you follow the correct procedures. First, make sure all of your batteries are fully charged before installing them into your golf cart. Second, ensure that all battery connections are tight and free of loose debris to prevent any electrical arcing or damage to your circuit.

Remember that golf cart batteries contain acid which can be hazardous if mishandled. Always wear gloves and safety goggles when working on them. If you’re unsure how to do something, seek professional advice or assistance.
