Electric golf carts for sustainable transportation

Throughout my years in battery manufacturing, I've encountered many operators considering switching from lithium to lead-acid batteries1, often driven by initial cost concerns.

While it is technically possible to replace a lithium battery with a lead-acid battery in a golf cart, it's generally not recommended due to performance differences, weight variations, and system compatibility issues. This switch often results in reduced performance and higher long-term costs.

Having guided numerous golf cart operators through battery decisions, I've gathered extensive data on the implications of switching between battery types. Let me share insights from real-world implementations and testing.

Working closely with fleet operators like James Peterson, I've observed that switching from lithium to lead-acid batteries often leads to unexpected challenges and costs. Understanding these factors is crucial for making an informed decision about your golf cart's power system.

What Are the Key Differences Between Lithium and Lead-Acid Batteries for Golf Carts?

My experience in battery system development has revealed significant differences between these technologies that affect golf cart performance.

Key differences include weight (lithium is 60-70% lighter)2, cycle life (lithium lasts 3-4 times longer)3, maintenance requirements (lithium needs minimal maintenance)4, and performance consistency (lithium maintains stable voltage longer)5.

Through extensive testing and field applications, we've documented these differences in detail. Let me share our comparative analysis.
