7. Maintenance

To ensure the longevity and optimal performance of your HumsiENK LiFePO4 battery, follow these general maintenance guidelines:

• Temperature Management: Operate and store the battery within the recommended temperature ranges (Charge: 0°C to 55°C; Discharge: -20°C to 60°C; Storage: -10°C to 35°C). Avoid extreme temperatures.
• Regular Monitoring: Periodically check the battery status via the Bluetooth app to ensure all parameters are within normal operating limits.
• Clean Connections: Ensure all cable connections are clean, tight, and free from corrosion to prevent resistance and overheating.
• Avoid Deep Discharge: While the BMS protects against over-discharge, prolonged operation at very low State of Charge (SOC) can impact overall lifespan.

8. Troubleshooting

The integrated BMS provides comprehensive protection. If the battery is not functioning as expected, check the following:

• LED Indicators: Observe the LED indicators on the front panel for any fault or alarm signals. Refer to the user manual for specific LED patterns and their meanings.
• BMS App: Use the mobile app to check detailed battery status, including individual cell voltages and temperatures, to identify any specific issues.
• Circuit Breaker: Ensure the built-in air switch (circuit breaker) is in the 'ON' position. If it has tripped due to an overload, switch it off and then back on after resolving the cause of the overload.
• Connections: Verify all power and communication cables are securely connected.

For persistent issues, refer to the detailed troubleshooting section in the full user manual or contact customer support.
