1. 72V 50Ah Lithium Golf Cart Battery Basics

What are 72V 50Ah lithium golf cart batteries?
72V 50Ah lithium batteries are lightweight, high-power energy solutions for golf carts. They use LiFePO4 chemistry for long lifespan (2,000+ cycles) and faster charging than lead-acid. Ideal for extended range and reduced maintenance.

Benefits of lithium vs lead-acid golf cart batteries?
Lithium offers 3x longer lifespan, 50% lighter weight, and 80% efficiency vs 50% in lead-acid. No maintenance, faster charging, and stable voltage under load make them superior.

How long do 72V 50Ah lithium batteries last?
With 2,000-3,000 cycles, these batteries last 5-10 years, depending on usage. They retain 80% capacity after 2,000 cycles, outperforming lead-acid’s 300-500 cycles.

2. Charging & Compatibility

Charging time for high-capacity lithium golf cart batteries?
A 72V 50Ah battery charges fully in 2-4 hours with a standard charger. Fast chargers cut this to 1-2 hours, thanks to lithium’s high charge acceptance rate.

Are 72V lithium batteries compatible with all golf carts?
Most 72V lithium batteries fit carts designed for 72V systems. Adapters may be needed for older models. Verify voltage, BMS, and connector compatibility before purchase.

Safety features in 72V 50Ah lithium golf cart batteries?
Built-in BMS protection prevents overcharge, overheating, and short circuits. LiFePO4 chemistry is non-flammable, and sealed designs resist moisture and dust.

3. China OEM & Wholesale

Top manufacturers for China OEM 72V 50Ah golf cart batteries?
Leading Chinese OEMs include CATL, EVE Energy, and BYD. Smaller specialized suppliers offer customizable BMS, housings, and certifications at competitive prices.

Applications beyond golf carts for 72V 50Ah lithium batteries?
These batteries power solar storage, EVs, marine, and industrial equipment. Their high energy density suits applications needing lightweight, durable power.

Advantages of China OEM lithium batteries over competitors?
Lower costs, customizable designs, and bulk discounts make China OEMs preferred. Many comply with global certifications (UN38.3, CE, RoHS) for export.

4. Specifications & Performance

What are the specifications of 72V 50Ah Li-ion batteries?
Standard specs include 72V nominal voltage, 50Ah capacity, 100A BMS, and 2,000+ cycles. Weight is ~25kg, half that of lead-acid equivalents.

Why choose Li-ion over lead-acid for golf cart batteries?
Li-ion provides higher efficiency, zero maintenance, and consistent power until discharged. They’re lighter and charge 3x faster than lead-acid.

How do 72V 50Ah batteries perform in electric golf carts?
They deliver 30-50 miles per charge, with steady voltage for uphill climbs. No capacity loss under partial charge, unlike lead-acid.

5. Purchasing & Warranty

Where to buy wholesale 72V 50Ah Li-ion golf cart batteries?
Alibaba, Made-in-China, and direct factory purchases offer wholesale deals. MOQs start at 50-100 units, with discounts for bulk orders.

Warranty periods for 72V 50Ah lithium batteries from China OEMs?
Reputable suppliers provide 3-5 year warranties, covering defects and premature capacity loss. Some offer prorated extensions for long-term contracts.

How does China factory pricing compare for 72V 50Ah batteries?
China OEMs offer 30-50% lower prices than Western brands due to scaled production. Bulk orders further reduce per-unit costs.

6. Cold Weather Performance

How does cold weather affect 72V 50Ah golf cart battery performance?
Below 0°C (32°F), capacity drops 10-20%, but LiFePO4 performs better than lead-acid. Built-in BMS heaters mitigate extreme cold effects.

Best maintenance practices for 72V golf cart batteries in winter?
Store batteries indoors when unused. Charge at room temperature and avoid full discharges. Use a thermal blanket if operating below -10°C.

Charging recommendations for 72V golf cart batteries in cold?
Charge above 0°C to prevent damage. Some BMS systems auto-limit charging in freezing temps. Pre-warm batteries if necessary.
