5. Installation and Setup
5.1 Pre-Installation Checks
- Ensure the golf cart's power is completely off before beginning installation.
- Verify the battery dimensions against the available space in your golf cart's battery compartment. Some modification to the battery tray may be required for optimal fit.
- Confirm that your golf cart's electrical system is compatible with a 36V lithium battery.
- If your golf cart has 12-volt accessories (e.g., headlights), a 36V/48V to 12V converter will be necessary.
5.2 Battery Installation
- Remove Old Batteries: Carefully disconnect and remove existing lead-acid batteries, noting the original wiring configuration.
- Position New Battery: Place the TEMGOT lithium battery securely in the battery compartment. Ensure it is stable and does not shift during operation. The battery can be mounted in any position due to its sealed design.
- Connect Wiring:
- Connect the main negative wire (often from the motor) to the negative terminal of the TEMGOT battery.
- Connect the main positive wire (often to the forward/reverse switch) to the positive terminal of the TEMGOT battery.
- Use the provided M8 terminals and screws, ensuring all connections are tight and secure.
- For older resistor carts, if the reverse cable was wired for 18 volts, you may need to run it directly to the positive terminal or jump it over the main positive cable to ensure full speed in reverse.
- Install External Switch (Optional): The battery includes an external switch and cable. Install this switch in a convenient location, such as the dashboard, to easily turn the battery on/off without lifting the seat.
- Secure Battery: While the metal case provides durability, ensure the battery is properly secured to prevent movement, especially on rough terrain.
5.3 Initial Charge
After installation, it is recommended to fully charge the battery before first use.
- Connect the 42.6V 20A dedicated charger to the battery's charging port.
- Plug the charger into a suitable AC power outlet.
- Allow the battery to charge until the charger indicates a full charge (typically 5-6 hours). The battery's LCD screen or app will also show the charge status.
Figure 5.1: Dedicated 42.6V 20A Charger. This charger supports fast charging in 5-6 hours and includes protections against input voltage abnormalities, hardware over-voltage, and short circuits.
6. Operation
6.1 Turning the Battery On/Off
- Main Battery Switch: The battery features a main switch with a green indicator light. When the switch is turned on, the indicator light will be green, confirming the battery is active.
- External Switch: If installed, use the external switch to power the battery on or off remotely.
6.2 Monitoring Battery Status
The TEMGOT battery offers two methods for real-time monitoring of its status:
- Smart LCD Screen: The included 2.8-inch touch screen can be mounted in a convenient location to display battery information such as state of charge, voltage, current, and remaining time.
- APP Monitoring: Download the dedicated TEMGOT app to your smartphone. The app provides live information, allowing you to monitor the battery status wirelessly.

7. Charging
- Always use the provided 42.6V 20A dedicated LiFePO4 charger. Using an incompatible charger can damage the battery and void the warranty.
- Connect the charger to the battery's charging port first, then plug it into a standard AC outlet.
- The charger will automatically stop charging once the battery is full.
- Charging typically takes 5-6 hours from a fully discharged state.
- It is safe to leave the battery connected to the charger after it is fully charged, as the charger will enter float mode.
8. Maintenance
The TEMGOT LiFePO4 battery is designed to be maintenance-free, eliminating the need for regular watering or terminal cleaning associated with lead-acid batteries. However, general care practices will ensure optimal performance and longevity:
- Regular Inspection: Periodically check battery terminals for cleanliness and tightness. Ensure there are no loose connections.
- Cleaning: If necessary, wipe the battery casing with a dry or slightly damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% capacity and stored in a cool, dry place away from direct sunlight and extreme temperatures.
- BMS Protection: The built-in 160A BMS provides comprehensive protection against over-charge, over-discharge, over-current, high/low temperatures, and short-circuiting, reducing the need for user intervention.
9. Troubleshooting
If you encounter issues with your TEMGOT battery, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not turning on | Main switch off; External switch off; Deep discharge; BMS protection activated. | Ensure main battery switch and external switch are ON. Connect to charger to reactivate from deep discharge or BMS protection. |
| Battery not charging | Charger not connected properly; Faulty charger; BMS protection (over-voltage, low temperature). | Check all charger connections. Ensure charger is plugged into a live outlet. Verify charger is the correct 42.6V 20A model. Move battery to a warmer environment if ambient temperature is too low. |
| Reduced range or power | Battery not fully charged; High power draw; Extreme temperatures. | Ensure battery is fully charged before use. Reduce heavy loads if possible. Operate within recommended temperature ranges. |
| BMS shutdown during operation | Over-current; Over-discharge; High/low temperature. | Reduce load on the golf cart. Allow battery to cool down or warm up to operating temperature. Charge the battery if it's deeply discharged. The BMS will automatically reset once conditions return to normal. |
| LCD screen or app not displaying data | Loose connection; Battery off; App not connected via Bluetooth. | Check connections to the LCD screen. Ensure the battery is powered on. For app, ensure Bluetooth is enabled on your device and the app is correctly paired with the battery. |
If the problem persists after attempting these solutions, please contact TEMGOT customer support.
