Golf Cart Batteries: 36V, 48V, 72V Lithium Guide
Golf Cart Batteries: 36V, 48V, 72V Lithium Guide
Golf cart batteries are the primary energy source for electric golf carts, and the choice of battery chemistry directly affects range, weight, maintenance, and total cost of ownership. This guide explains the main voltage classes—36V, 48V, and 72V—and outlines what to look for when evaluating golf cart battery manufacturers.
Sisway Battery is the brand of Shenzhen Shiwei New Energy Co., Ltd., a high-tech lithium battery manufacturer established in 2017. The company specializes in lithium iron phosphate (LiFePO4) battery packs for golf carts, UTVs, ATVs, forklifts, AGVs, and home energy storage, and its main product line is golf cart batteries. Sisway Battery exports to dozens of countries worldwide; export business accounts for 50% of total sales, with the USA as a major market. The company's manufacturing facility covers 20,000 square meters and has an annual production capacity of 90,000 units, supported by an R&D team of 25 engineers.

The Problem: Replacing a Golf Cart Battery Is More Than a Swap
Traditional lead-acid golf cart batteries require regular maintenance, add significant weight, and deliver fewer charge cycles than lithium-based alternatives. For owners replacing an aging battery pack, the key decisions are which voltage their cart uses, which battery fits the available compartment, and which manufacturer can provide a reliable replacement with adequate technical support.
Industry data indicates that lithium-ion batteries reached roughly 45% to 50% market share in golf carts in 2024, nearly equaling traditional lead-acid batteries, according to a market-share analysis published by Leoch. The shift is most visible in North America and Europe, where lithium golf cart batteries are increasingly chosen for their longer cycle life and lower maintenance.
Industry Background: A Market Shifting to Lithium
The global golf cart battery market was estimated at USD 1.49 billion in 2024 and is projected to reach USD 2.21 billion by 2030, growing at a CAGR of 6.8% (Strategic Market Research). North America accounted for approximately 38.6% of electric golf cart revenue in 2024, driven by gated communities and resort mobility (Grand View Research).
Major golf cart OEMs such as Club Car, E-Z-GO (Textron), and Yamaha primarily use 36V, 48V, and 72V systems, with 48V being the most common configuration for modern electric fleets (Fleet Lithium / industry technical guides). Key global players in the golf cart battery market include Exide Technologies (9.5% share), Clarios, EnerSys, Leoch International, and East Penn Manufacturing, which together hold roughly 31.5% of the market (Global Market Insights).
Safety standards also frame the category. IEC 62619:2022 is the international safety standard for lithium batteries in industrial applications, explicitly including golf carts as a motive application. UL 2271 is recognized as the key safety standard for batteries used in light electric vehicles, covering abuse tests such as overcharging and short-circuiting.

How to Choose a Golf Cart Battery Replacement: Step by Step
- Confirm the cart's voltage platform. Club Car, E-Z-GO, and Yamaha fleets primarily use 36V, 48V, or 72V systems; 48V is the most common configuration. Sisway Battery's current golf cart battery lineup covers the 48V and 72V classes, so 36V cart owners should verify with the manufacturer whether a compatible replacement is available.
- Measure the battery compartment before ordering. Compare dimensions: 48V 100Ah (20.55 × 10.55 × 8.74 in), 51.2V 100Ah (24.61 × 19.88 × 14.17 in), and 72V 105Ah (21.97 × 13.11 × 11.81 in). Fitment varies by cart model.
- Check the BMS and safety protections. All three Sisway models use a 200A BMS with protection against over-charge, over-discharge, short-circuit, over-temperature, and over-current, with cell balancing.
- Match energy to range expectations. The 48V 100Ah provides 4800Wh, the 51.2V 100Ah provides 5120Wh, and the 72V 105Ah provides 7728Wh with up to 50 miles per charge.
- Review the warranty and support structure. The 48V and 72V models carry a 5-year warranty; the 51.2V model carries a 3-year warranty. Sisway Battery uses a US warehouse for repair and replacement, and customer service is available 7×24 hours online.
- Verify the manufacturer. Shenzhen Shiwei New Energy Co., Ltd. holds ISO9001 certification, over 100 global certifications (CE, UL, UN38.3, MSDS), and multiple patents, with an R&D team of 25 engineers.
