5. Setup

5.1 Initial Inspection and Charging

Upon receiving your battery, inspect it for any visible damage. The battery typically arrives partially charged. For optimal performance and lifespan, it is recommended to fully charge the battery before its first use.

• Use a dedicated 24V (29.2V) LiFePO4 charger. A 20A charger is recommended for a full charge in approximately 5 hours. A 100A charger can achieve a full charge in about 1 hour.
• Ensure the charger's voltage and current settings are compatible with LiFePO4 batteries.

5.2 Connecting the Battery

The battery is equipped with M8 terminals. Ensure all connections are secure and use appropriate gauge wiring for your application to prevent overheating and power loss.

5.3 Series and Parallel Connections

The XZNY Compact 24V 100Ah battery offers excellent expandability:

• Series Connection: Up to 2 batteries can be connected in series to achieve a higher voltage (e.g., two 24V batteries in series create a 48V system).
• Parallel Connection: Up to 5 batteries can be connected in parallel to increase capacity (e.g., five 100Ah batteries in parallel create a 500Ah system).
• A maximum system capacity of 25.6KWh can be achieved.

When connecting batteries in series or parallel, ensure all batteries are of the same model, capacity, and state of charge. Use appropriate cables and fuses for safety.

6. Operating Instructions

6.1 Battery Management System (BMS)

The integrated 100A BMS provides comprehensive protection for the battery, ensuring safe and reliable operation. Key protection features include:

• Low Temperature Protection: Automatically cuts off charging at 32°F (0°C) and stops discharging at -8°F (-22°C) to prevent damage.
• High Temperature Protection: Prevents overheating during operation.
• Overcharge Protection: Prevents damage from excessive charging voltage.
• Overdischarge Protection: Prevents damage from excessive discharge.
• Overcurrent Protection: Safeguards against excessive current draw.
• Short-Circuit Protection: Automatically disconnects in case of a short circuit.

7. Maintenance

The XZNY LiFePO4 battery requires minimal maintenance due to its robust design and long lifespan. Follow these guidelines to ensure optimal performance and longevity:

• Regular Inspection: Periodically check the battery terminals and connections for corrosion or looseness. Clean terminals if necessary and ensure connections are tight.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% of its capacity. Store in a cool, dry place, away from direct sunlight and extreme temperatures.
• Charging: Always use a compatible LiFePO4 charger. Avoid overcharging or deep discharging the battery, although the built-in BMS provides protection against these conditions.
• Cleaning: Keep the battery clean and free of dust and debris. Use a dry cloth for cleaning.

8. Troubleshooting

If you encounter issues with your XZNY LiFePO4 battery, consider the following common troubleshooting steps:

• Battery Not Charging:
  • Check if the charger is properly connected and functioning.
  • Verify that the charger is compatible with LiFePO4 batteries and has the correct voltage output.
  • The BMS may have activated low-temperature protection (charging cut-off at 32°F / 0°C). Move the battery to a warmer environment.
  • Check for any blown fuses in your system.
• Battery Not Discharging/No Power Output:
  • Ensure all connections are secure and free of corrosion.
  • The BMS may have activated overdischarge protection (if the battery voltage dropped too low). Recharge the battery.
  • The BMS may have activated low-temperature protection (discharging cut-off at -8°F / -22°C). Move the battery to a warmer environment.
  • Overcurrent or short-circuit protection may have been triggered. Disconnect the load, wait a few minutes, and reconnect. Reduce the load if it exceeds the battery's continuous discharge current.
• Unusual Odor or Swelling: Immediately disconnect the battery from all loads and chargers. Do not attempt to use it. Contact customer support.
