4. Installation
Before installation, ensure the battery is fully charged and the golf cart's power is off. Refer to your golf cart's manual for specific battery compartment access and wiring diagrams.
Steps:
- Preparation: Turn off the golf cart's main power switch. Disconnect the old battery system, ensuring no live wires are exposed.
- Placement: Carefully place the KEPWORTH LiFePO4 battery into the battery compartment. The battery is designed with handles for easier transport and positioning.
- Wiring: Connect the battery terminals to your golf cart's electrical system. Ensure correct polarity (positive to positive, negative to negative). Secure all connections tightly.
- Smart Monitor Connection: Connect the smart battery monitor LCD to the designated port on the battery.
- Final Check: Double-check all connections. Turn on the battery's power switch (if applicable) and then the golf cart's main power switch.

Storage:
- For long-term storage, charge the battery to approximately 50% State of Charge (SOC).
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Periodically check the battery's charge level during storage and recharge if necessary to prevent deep discharge.
9. Troubleshooting
This section addresses common issues you might encounter with your KEPWORTH LiFePO4 battery.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected properly; Charger malfunction; BMS temperature cut-off activated. | Ensure charger is securely connected and plugged into a live outlet. Check charger indicator lights. Allow battery to return to normal operating temperature if too hot/cold. |
| Battery not providing power | Battery switch off; Low State of Charge (SOC); BMS protection activated (over-discharge, over-current, short circuit); Loose connections. | Turn on battery switch. Charge the battery. Check smart monitor for BMS fault codes. Inspect and tighten all connections. |
| Reduced range/performance | Battery not fully charged; Extreme operating conditions; Aging battery (after many cycles). | Ensure full charge before use. Operate within recommended temperature range. While LiFePO4 batteries have long lifespans, performance will gradually decrease after 4000+ cycles. |
If issues persist, contact KEPWORTH customer support.
