4. Setup
4.1 Unpacking and Inspection
Upon receiving your battery, carefully unpack it and inspect for any signs of physical damage. If any damage is found, contact customer support immediately.
4.2 Initial Charge
It is recommended to fully charge the battery before its first use to ensure optimal performance and calibration of the BMS.
4.3 Electrical Connection
Ensure all connections are secure and correctly polarized. Incorrect wiring can cause damage to the battery and connected devices.
- Cable Sizing: Use appropriately sized cables for your application to handle the expected current draw. Refer to electrical guidelines for proper cable gauge selection.
- Terminal Connection: Connect cables to the M8 terminals. Ensure a tight and secure connection to prevent resistance and overheating.
- Series/Parallel Configuration: The battery supports up to 4-series and 4-parallel connections for increased voltage or capacity. When connecting multiple batteries, ensure all batteries are at a similar state of charge before connecting them in parallel. For series connections, ensure all batteries are of the same voltage and capacity.

5. Operating Instructions
5.1 Charging
The HumsiENK LiFePO4 battery can be charged using various methods:
- LiFePO4 Charger: Use a dedicated LiFePO4 battery charger with appropriate voltage and current settings.
- Solar Panel + MPPT: Connect to a solar panel system with a Maximum Power Point Tracking (MPPT) charge controller optimized for LiFePO4 batteries.
- Generator: A generator with a compatible charger can also be used.
Ensure the charging voltage is within the specified range (typically 14.2V - 14.6V for 12V LiFePO4 batteries) and the charging current does not exceed the BMS limit (100A).
5.2 Discharging
The battery can deliver a continuous discharge current up to 100A, as managed by the built-in BMS. Avoid exceeding this limit to prevent the BMS from triggering protection and disconnecting the load.

5.3 Temperature Ranges
The battery is designed to operate within specific temperature ranges:
- Discharge Temperature: -4°F to 158°F (-20°C to 70°C)
- Charge Temperature: 32°F to 158°F (0°C to 70°C)
The BMS will automatically cut off charging if the temperature falls below 32°F (0°C) to prevent damage.

6. Maintenance
Proper maintenance ensures the longevity and reliability of your battery:
- Regular Inspection: Periodically check battery terminals for corrosion or loose connections. Clean terminals as needed.
- Keep Clean: Keep the battery surface clean and dry.
- 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 within the recommended temperature range. Avoid storing in direct sunlight or extreme temperatures.
- Avoid Deep Discharge: While the BMS protects against over-discharge, regularly charging the battery before it reaches very low levels can extend its overall lifespan.
7. Troubleshooting
If you encounter issues with your HumsiENK battery, consider the following common troubleshooting steps:
- Battery Not Charging:
- Check charger connections and ensure the charger is compatible with LiFePO4 batteries.
- Verify that the charging temperature is above 32°F (0°C). The BMS will prevent charging below this temperature.
- Inspect battery terminals for loose connections or corrosion.
- No Power Output:
- Check if the battery is fully discharged. Recharge if necessary.
- Ensure all connections to the load are secure.
- The BMS may have triggered a protection mode (e.g., over-discharge, over-current, short-circuit). Disconnect the load, wait a few minutes, and reconnect. If the issue persists, contact support.
- Bluetooth App Connectivity Issues:
- Ensure your smartphone's Bluetooth is enabled and you are within 15 meters of the battery.
- Restart the app and try reconnecting.
- Check for app updates.
- Unusual Odor or Swelling: Immediately disconnect the battery from all loads and chargers. Do not attempt to use or repair. Contact customer support.
