6. Setup and Installation
6.1 Pre-installation Checklist
- Ensure the vehicle is turned off and in "Tow Mode" (if applicable).
- Gather necessary tools: wrenches, screwdrivers, wire cutters, heat shrink tubing, and a multimeter.
- Wear appropriate PPE.
6.2 Removing Old Batteries
- Lift the seat to access the battery compartment.
- Disconnect any onboard chargers or accessories from the old batteries.
- Carefully disconnect the negative (-) terminals first, followed by the positive (+) terminals. Insulate cable ends immediately to prevent accidental short circuits.
- Remove any brackets or hold-downs securing the old batteries.
- Safely remove the old lead-acid batteries from the compartment. Note their significant weight.
Video: This video demonstrates the process of removing old lead-acid batteries from a golf cart, including disconnecting an onboard charger and preparing the compartment for a new lithium battery. It highlights the importance of setting the cart to "Tow Mode" and carefully handling battery connections.
6.3 Preparing Battery Compartment
- Clean the battery compartment thoroughly, removing any debris, corrosion, or old battery acid residue.
- Consider applying a protective coating or paint to the metal frame to prevent future corrosion.
- Fabricate or install a custom battery tray if necessary to securely fit the new LiFePO4 battery. Ensure it is robust enough to hold the battery in place.
Video: This segment shows the cleaning and preparation of the golf cart's battery compartment after removing the old batteries. It also details the fabrication of a custom battery tray to securely house the new lithium battery.
6.4 Installing New Battery
- Carefully place the Cloudenergy LiFePO4 battery into the prepared compartment/tray.
- Secure the battery using the provided straps or custom hold-downs to prevent movement during operation.
- Connect the main positive (+) cable to the battery's positive terminal.
- Connect the main negative (-) cable to the battery's negative terminal.
- Connect the provided Anderson-type plug for the charger to the battery terminals.

6.5 OBC Bypass (if applicable)
For some golf cart models (e.g., Club Car DS with On-Board Computer), it may be necessary to bypass the existing OBC to ensure proper charging and operation with the LiFePO4 battery. This typically involves:
- Locating the OBC wiring harness, usually near the battery compartment.
- Disconnecting the main plug from the OBC.
- Identifying and jumping specific wires (e.g., blue and white wires) within the harness to complete the circuit, bypassing the OBC's control over charging.
- Disconnecting or insulating any ground wires previously connected to the OBC.
- Always consult specific vehicle wiring diagrams or a qualified technician if unsure.

8. Maintenance
- Keep battery terminals clean and free of corrosion.
- Regularly check all cable connections to ensure they are secure.
- Avoid fully discharging the battery whenever possible to maximize lifespan, although the BMS provides protection.
- Store the battery in a cool, dry place if not in use for extended periods. Ensure it is charged to at least 50% before storage.
9. Troubleshooting
- Battery Not Powering On: Check the ON/OFF switch on the battery. Ensure all main cables are securely connected.
- Battery Not Charging: Verify the charger is properly connected to the battery and a working power outlet. Check the charger's indicator lights. Ensure the OBC bypass (if applicable) is correctly implemented.
- BMS Tripping (Battery Shuts Off): This can occur due to excessive current draw (e.g., climbing a steep hill), over-discharge, or extreme temperatures. Reduce the load, allow the battery to rest, or check for obstructions. If using a Bluetooth app, check BMS parameters and adjust if necessary (consult customer support for guidance).
- Inaccurate Display Readings: Ensure the LCD display cable is securely connected to the battery. If using the Bluetooth app, ensure a stable connection.
