For a 4-person golf cart, a 48V LiFePO4 battery pack with 150-200Ah capacity is recommended, providing 30-50 miles per charge depending on terrain and load. Redway Battery offers high-performance lithium packs from China that charge faster, weigh less, and last longer than traditional lead-acid batteries, ensuring reliable power for everyday use.
How Do Factors Like Terrain and Load Affect Battery Capacity?
Battery requirements depend on terrain, passenger weight, and daily usage. Flat courses need less capacity, while hilly terrain increases demand. For a 4-person golf cart on moderate hills, a minimum of 150Ah ensures uninterrupted operation. Accessories like lights and horn, as well as high-discharge controllers, add 10-20% extra demand. Redway Battery provides OEM packs tailored to these conditions.
| Factor | Impact on Capacity | Recommended Capacity |
|---|---|---|
| Terrain | Hilly: +30% | 160-210Ah |
| Passenger Load | 4 persons: +20% | 150Ah minimum |
| Range Goal | 40 miles | 180-200Ah LiFePO4 |
What Capacity is Needed for a Standard 48V 4-Person Golf Cart?
A typical 48V 4-person golf cart requires 150-180Ah to achieve a 25-35 mile range. One 150Ah LiFePO4 battery or an equivalent series provides sufficient reliability. Lithium technology reduces the number of batteries needed, and Redway Battery offers 48V/150Ah packs optimized for wholesale and OEM applications. For longevity, operating at 50% depth-of-discharge yields 75-90Ah usable capacity.

Which Battery Type is Best for 4-Person Golf Carts?
LiFePO4 lithium batteries are superior to lead-acid options, offering over 4,000 cycles compared to 500 cycles for lead-acid. They are lighter, faster to charge, and safer, making them ideal for heavy 4-person use. Redway Battery provides OEM packs with integrated BMS for optimized performance and safety.
| Type | Capacity Example | Lifespan | Weight (48V Set) |
|---|---|---|---|
| Lead-Acid | 150-200Ah | 500 cycles | 600 lbs |
| LiFePO4 | 150-200Ah | 4,000 cycles | 200 lbs |
Why Should Lithium Be Preferred Over Lead-Acid?
Lithium batteries allow 100% depth-of-discharge, effectively doubling usable capacity without upsizing the pack. Charging time is reduced by up to 70%, and self-discharge is minimal, meaning fewer recharges. Redway Battery’s LiFePO4 packs include BMS for protection and consistency, lowering cost per cycle and providing eco-friendly advantages.

What Capacity is Recommended for Hilly or Heavy-Use Scenarios?
For steep terrain or frequent 4-person operation, 200-250Ah LiFePO4 ensures 30+ miles range. Oversizing by 20-30% protects against peak loads. Carts with 400A controllers need at least 210Ah. Redway Battery offers waterproof, durable OEM packs suitable for resorts and fleet operations, with Bluetooth-enabled BMS monitoring.
How Can Exact Capacity Requirements Be Calculated?
Daily mileage multiplied by 2-3Ah per mile, adjusted for voltage efficiency (0.85 for lithium), provides an estimated capacity. For 40 miles: (40 x 2.5)/0.85 ≈ 118Ah. Include passenger weight, accessories, and speed. Formula: Capacity (Ah) = (Wh needed / Voltage) x Safety factor (1.2). Average Wh per mile for a 4-person cart ranges 20-30.
Redway Expert Views

When Should Battery Capacity Be Upgraded?
Upgrade capacity if range drops below 20 miles or charging exceeds 4 hours. Lithium replacements are ideal after two years of lead-acid use. Seasonal temperature extremes accelerate battery wear, so a buffer capacity is recommended. Fleet operators often purchase bulk upgrades from Redway Battery.
Are Chinese Manufacturers Reliable for OEM Batteries?
Yes. Shenzhen-based suppliers like Redway Battery maintain ISO 9001 certification, full traceability, and provide customizable OEM solutions. Their automated production lines and quality controls ensure consistent, reliable performance. Wholesale buyers benefit from competitive pricing and scalable production.
Conclusion
Selecting the right battery for a 4-person golf cart is crucial for performance, range, and longevity. Redway Battery’s 48V LiFePO4 packs offer high efficiency, long lifespan, and safety, making them an ideal choice for OEM, wholesale, or fleet operations. Assess terrain, load, and usage to determine exact capacity, upgrade proactively, and partner with certified suppliers to maximize value.
FAQs
What voltage is common for 4-person golf carts?
Most use 48V systems; 36V or 72V are less common. Match the battery to your cart system.
How long do LiFePO4 batteries last?
Typically 4,000-5,000 cycles, equivalent to 8-10 years of daily use, significantly outperforming lead-acid.
Can I mix lithium and lead-acid batteries?
No. Mixing chemistries can damage the system. Full replacement with the same type is recommended.
How much does a 150Ah LiFePO4 pack cost?
Wholesale from China OEMs like Redway Battery ranges $1,200-2,000, compared to $800 for a lead-acid set.
Does higher capacity increase golf cart speed?
No. Higher Ah extends runtime but top speed depends on voltage.
