If you’re upgrading or replacing your golf cart’s batteries, compatibility is key. While it might seem logical to use four 12-volt batteries to reach 48 volts (4 x 12V = 48V), this setup is not suitable for a 36-volt golf cart. Here’s why:  

Voltage Mismatch:

 A 36-volt cart is designed to operate with six 6-volt batteries wired in series (6V x 6 = 36V). Using four 12-volt batteries would create a 48-volt system, overwhelming the cart’s motor, controller, and electrical components. This mismatch can cause overheating, damage, or even safety hazards.  

Capacity and Runtime:  

Even if you reconfigure four 12V batteries (e.g., wiring three in series for 36V), you’d sacrifice capacity (measured in amp-hours). Fewer batteries mean less stored energy, reducing your cart’s range and performance.  

Safety Risks:  

Improper wiring or voltage can strain the system, leading to premature failure of parts like solenoids or chargers. Always follow the manufacturer’s voltage specifications.  

The Right Solution:

 Stick with six 6-volt batteries for a 36V cart, or consider upgrading to a 48V system (with compatible components). For a modern alternative, lithium batteries like the PowerUrus battery offer lightweight, high-capacity options—but ensure your cart’s voltage matches the battery bank.  

Final Tip:  

Consult a professional before altering your cart’s power system. Investing in the correct setup saves money, ensures safety, and keeps your cart running smoothly.  

When in doubt, prioritize compatibility—your golf cart (and wallet) will thank you!
