Installing Lithium Batteries in Your President Electric Golf Cart: Step-by-Step Guide

/in /by

1. Preparation Before Installation

Before you begin, ensure you have all the necessary tools and safety measures in place.

  • Verify compatibility: Confirm your President golf cart’s voltage and battery compartment size.
  • Safety precautions: Disconnect the main power, wear protective gloves, and work on a stable surface.
  • Tools checklist: Wrenches, screwdrivers, multimeter, and any mounting hardware required.

⚠️ Note on President Models: Installation may vary slightly depending on your model. For example:

  • i3 Series (48V): Two lithium battery modules with separate BMS connections.
  • i2 Series (36V): Single battery module fits standard compartment; ensure correct polarity.
  • Other models: Always check compartment dimensions and BMS compatibility before installation.

2. Step-by-Step Installation Guide

Step 1: Remove old batteries

  • Carefully disconnect and remove existing lead-acid batteries. Keep terminals covered to prevent short circuits.

Step 2: Position the lithium battery modules

  • Place lithium batteries in the compartment, ensuring they fit securely.

Step 3: Connect terminals

  • Connect the positive (+) terminal first, followed by the negative (-)
  • Ensure all connections are tight and corrosion-free.

Step 4: Integrate the BMS

  • Connect the built-in smart BMS to monitor voltage, current, and temperature.
  • Verify BMS wiring matches the cart’s system configuration.

Step 5: Final inspection

  • Double-check all connections and mounting. Make sure batteries are secure and there are no loose wires.

3. First Charge and System Testing

  • Perform the initial charge according to the lithium battery manufacturer’s instructions.
  • Monitor battery status using the BMS or monitoring app, checking voltage, current, and temperature.
  • Conduct a short test drive to ensure the cart operates correctly and the range meets expectations.

4. Maintenance and Best Practices

  • Regular monitoring: Check voltage, temperature, and state-of-charge daily or weekly.
  • Avoid over-discharge: Charge before the battery drops below ~20%.
  • Avoid overcharging: Disconnect after full charge to prevent stress on the cells.

Proper Storage for Lithium Batteries During Inactivity

If your President golf cart will be idle for an extended period (e.g., winter or off-season), follow these storage tips to protect your lithium batteries:

  1. Charge Level Before Storage
    • Store batteries at 40–60% state-of-charge.
    • Avoid fully charged or fully depleted batteries to prevent stress and capacity loss.
  2. Temperature Control
    • Keep batteries in a cool, dry environment (ideally 15–25°C / 59–77°F).
    • Avoid freezing temperatures or excessive heat, which can damage cells.
  3. Periodic Check and Top-Up
    • Check battery voltage every 1–2 months.
    • If voltage drops below ~40%, recharge to the recommended storage level.
  4. Disconnect From Cart
    • Disconnect the battery from the golf cart to prevent parasitic drain during long-term storage.

Following these storage practices helps maintain capacity, prevent degradation, and ensure your golf cart is ready for use after inactivity.

5. Choosing a Compatible Lithium Battery (Brief Note)

Selecting the correct lithium battery ensures safe and optimal performance:

  • Voltage & Capacity: Match your cart’s system voltage and daily range needs.
  • Physical Fit: Confirm battery compartment dimensions for a secure installation.
  • BMS Integration: Prefer batteries with built-in smart BMS for safety and monitoring.

6. Recommended Reading: Charging Tips for Maximum Lifespan

After installation, proper charging is critical to maximize battery life. Users often ask how to maintain cycles and longevity:

  • Avoid deep discharge; recharge before reaching 20%
  • Avoid overcharging; disconnect at 100%
  • Avoid charging in high temperatures
  • Periodically check battery status

7. Common Questions and Troubleshooting

  • Do I need a new charger? Only if your current charger is incompatible with lithium batteries.
  • What if the BMS triggers a fault? Follow the BMS troubleshooting guide; ensure connections are correct.
  • How to extend battery lifespan? Maintain proper charge cycles, monitor temperature, and store appropriately.
  • Handling temperature extremes: Avoid prolonged exposure to heat or freezing temperatures.

Conclusion

Installing lithium batteries in your President electric golf cart enhances performance, reduces maintenance, and extends battery life. By following proper installation steps, initial charging, storage, and maintenance practices, owners can ensure a reliable, safe, and long-lasting upgrade.

With careful battery selection (see recommended products here) and attention to charging best practices, your golf cart can enjoy efficient, high-performance operation for years to come.
