4.1 Compatibility and Dimensions
The Elefast 48V 100AH battery is designed with a narrow profile (approximately 9.8 inches wide) to fit most golf cart battery compartments, including Yamaha, EZ-GO, and Club Car models.
Image 4.1: The battery measures approximately 20.08 inches in length (21.25 inches including buckles), 9.76 inches in depth, and 9.45 inches in height. It weighs 104 lbs. The bolt size for terminals is M8.
Image 4.2: Visual comparison showing the Elefast battery's narrow width (min 9.6in) fitting easily into a golf cart compartment, unlike wider batteries (min 12in+) that may not fit.
Image 4.3: The Elefast battery is compatible with new and old models of EZ-GO, Yamaha, and Club Car golf carts.
Image 4.4: The battery is suitable for various golf cart configurations, including 2-seaters, 4-seaters, 5-seaters, and sightseers.
4.2 Installation
- Prepare the Golf Cart: Ensure the golf cart is turned off and the ignition key is removed. Disconnect the existing battery system.
- Position the Battery: Place the Elefast lithium battery in the designated battery compartment. The kit includes an anti-vibration mount and carabiner to keep the battery stable.
- Connect Cables: Connect the positive (+) and negative (-) terminals of the battery to the golf cart's electrical system using appropriate cables. Ensure connections are secure and tight. The battery uses Bolt Terminals (M8).
- Initial Charge: Before first use, fully charge the battery using the provided 58.4V 18A charger.
4.3 Initial Charging
The battery comes with a 58.4V 18A LiFePO4 fast charger. It is recommended to fully charge the battery before its first use.
Image 4.5: The 58.4V 18A fast charger can charge the battery from 50% to 100% in approximately 2.5 hours, and from 0% to 100% in about 5.5 hours. Always charge immediately if the voltage drops below 48V.
Image 4.6: The smart charger includes multiple protections: Over Current, Under Voltage, Over Voltage, Short Circuit, Over Temperature, and Air-Cooled Cooling. It automatically cuts off power when fully charged.
Image 4.7: The battery supports three charging methods: standard AC charging (1000W, 5.56H), solar charging (1200W, 4.2H), and generator charging (3000W, 1.7H). Solar charging voltage is 58.4V. If voltage drops below 46V, charging may not be possible; contact an engineer.
5. Operating Instructions
5.1 Powering On/Off
The battery features a discharge switch on its side. Turn the switch ON to power the golf cart and OFF when not in use or for storage.
5.2 Performance
The 48V 100AH battery provides a 3C discharge capacity of 600A, with a peak surge capability of up to 1000A. This allows for robust performance on various terrains, including inclines.
Image 5.1: A single charge can provide up to 50 miles (approximately 52 miles shown) of continuous golfing, sufficient for 10+ rounds and 18 holes. Actual mileage may vary based on road conditions and load factors.
Image 5.2: The battery supports a surge discharge of 1000A peak, allowing the golf cart to handle uphill sections and complex terrains. Over-current protection will auto-release in 32 seconds.
5.3 Monitoring Battery Status
The battery status can be monitored via the included 2.4-inch Bluetooth Display Screen or a mobile application.
Image 5.3: Both the Bluetooth Display and the mobile app provide real-time monitoring of battery performance, temperature, and charging cycles. Only one connection method (display or app) can be active at a time. For initial connection, connect the Bluetooth display via the app. To use the Bluetooth display, disconnect the app first. To use the phone app, disconnect the Bluetooth display first.
Image 5.4: Steps for APP Monitoring: 1. Download the app "xiaoxiang electric". 2. Register and Login. 3. Connect the battery's Bluetooth. 4. Bind MAC Address. Note: Disconnect Bluetooth display before connecting app, and vice-versa.
6. Maintenance
The Elefast lithium battery is designed to be maintenance-free. However, following these guidelines will ensure optimal performance and extend its lifespan:
- Regular Charging: Fully charge the battery after each use, especially if the voltage drops below 48V.
- Long-Term Storage: If storing the battery for an extended period, fully charge it and turn off the discharge switch on the side of the battery. Recharge periodically (e.g., every 3-6 months) to maintain battery health.
- Cleaning: Keep the battery terminals clean and free from corrosion. Use a dry cloth to wipe the battery exterior.
- Temperature: Store and operate the battery within recommended temperature ranges to prevent performance degradation.
7. Troubleshooting
The built-in 200A intelligent BMS (Battery Management System) protects the battery from various issues. If you encounter a problem, refer to the information below.
Image 7.1: The 200A BMS provides comprehensive protection against overcharging, over-discharging, over-current, overheating, and short circuits.
7.1 Common Issues and BMS Responses
- No Power Output: Check if the discharge switch on the battery is turned ON. If the battery was overloaded (exceeding 1000A peak surge), the BMS might have temporarily cut off power. It typically recovers automatically within 30 seconds.
- Charging Issues: Ensure the charger is properly connected and functioning. If the battery voltage drops below 46V, charging may not initiate.
- Low Temperature Protection: The BMS includes low-temperature protection:
Image 7.2: The BMS automatically cuts off charging if the temperature is below 32°F (0°C) and cuts off discharging if the temperature is below -4°F (-20°C). Auto-recovery for charging and discharging occurs when the temperature is above 41°F (5°C).
- Over-Current Protection: If the current draw exceeds safe limits, the BMS will cut off power. This protection will auto-release after approximately 32 seconds once the load is reduced.
If problems persist after checking these points, please contact Elefast customer support.
