Lithium Battery Sizing Guide for Commercial Golf Carts

Choosing the right lithium battery for your golf cart is essential for ensuring optimal performance, longevity, and reliability. Whether you're operating a 2-passenger cart on flat terrain or a 6-passenger lifted cart on moderate terrain, understanding how different battery sizes impact range and power is crucial. This guide simplifies the battery selection process based on cart type, terrain, speed, and controller capacity.

Understanding Battery Sizing for Golf Carts

The correct battery size depends on several factors, including:
✔️ Number of Passengers – More passengers require higher power output.
✔️ Lifted vs. Non-Lifted Carts – Lifted carts need larger controllers and more power.
✔️ Terrain – Flat terrain requires less power, while hilly or rough terrain demands more.
✔️ Speed Requirements – Higher speeds need stronger battery setups.
✔️ Controller Size – Larger controllers allow for greater acceleration and torque.

Let's break down battery sizing based on different cart types.

🔹 Economy Carts (2 Passenger)

• Terrain: Flat
• Lifted?: No
• Controller Size: Up to 250A
• Speed: Up to 14 mph
• Recommended Battery:
  • RS 48V 105AH: 30 – 45 miles range
  • 48V 168AH REC: 50 – 65 miles range
  • 48V 168AH SQ: 50 – 65 miles range

⚠️ No additional speed programs, flashes, or chips should be installed.

🔹 Modified Carts (2–4 Passenger)

• Terrain: Moderate
• Lifted?: Yes
• Controller Size: Up to 400A
• Speed: Up to 25 mph
• Battery Options:

⚠️ If driving on hilly terrain or carrying extra passengers, consider upgrading to a higher-capacity battery for improved range.

🔹 Highly Modified Carts (4–6 Passenger)

• Terrain: Moderate
• Lifted?: Yes
• Controller Size: Up to 600A
• Speed: Up to 30 mph
• Battery Options:

⚠️ For highly modified carts, Allied Battery recommends consulting their technical team for setup guidance to ensure safe performance and longevity.

💡 Key Takeaways

✅ Choosing the right battery depends on cart type, terrain, and modifications.
✅ Higher capacity batteries deliver longer range and better performance under load.
✅ Controller size and speed upgrades directly affect power demand and runtime.
✅ Consult Allied Battery for expert advice when building or upgrading lifted and multi-passenger carts.

Note: Ranges are estimates and can vary based on terrain, passenger weight, and driving habits. For the best results, monitor performance and choose a battery configuration that suits your real-world use.
