4. Setup and Installation

4.1. Initial Inspection

Upon receiving your battery, inspect it for any visible damage. If damage is found, contact your supplier immediately.

4.2. Connection Guidelines

The EPEVER LiFePO4 battery supports both parallel and series connections to meet various power requirements. Always ensure all batteries are at a similar State of Charge (SoC) before connecting them in parallel or series.

4.2.1. Parallel Connection (Max 4 Units)

For increased capacity while maintaining the nominal voltage, connect batteries in parallel. Connect all positive terminals together and all negative terminals together. Ensure all connecting cables are of appropriate gauge and length to minimize resistance.

5. Operating Instructions

5.1. Charging

Use a compatible LiFePO4 charger. The integrated self-heating function will activate automatically if the battery temperature is below 0°C during charging, ensuring safe and efficient charging in cold conditions. Monitor charging status via the "Xiaoxiang Electric" app.

5.2. Discharging

The battery can be discharged continuously up to 75A. The BMS will protect the battery from over-discharge. For optimal battery life, avoid consistently discharging to 0% DOD.

5.3. Monitoring with the App

The "Xiaoxiang Electric" app provides real-time data on your battery's performance, including:

• State of Charge (SoC)
• Voltage
• Current (Charge/Discharge)
• Temperature
• Cycle Count
• Individual Cell Voltages (if supported by app interface)

Refer to the app's internal help or user interface for detailed instructions on specific features and parameter adjustments.

6. Maintenance

The EPEVER LiFePO4 battery is designed for minimal maintenance. However, following these guidelines will help ensure its longevity and optimal performance:

• Regular Visual Inspection: Periodically check the battery and its terminals for any signs of damage, corrosion, or loose connections. Ensure terminals are clean and tight.
• Keep Clean: Wipe the battery casing with a dry, clean cloth. Do not use solvents or abrasive cleaners.
• Temperature Control: While the battery has self-heating, avoid prolonged exposure to extreme temperatures (hot or cold) outside its operating range when not in use.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% State of Charge (SoC) and stored in a cool, dry place. Recharge every 3-6 months to prevent deep discharge.
• Firmware Updates: Check the "Xiaoxiang Electric" app periodically for any available firmware updates for the battery's BMS.
