Setup and Installation
Proper installation is crucial for the safe and efficient operation of your Humsienk LiFePO4 battery. Always ensure the battery is disconnected from any loads or charging sources before making connections.
1. Pre-Installation Checks
- Inspect the battery for any visible damage.
- Ensure you have the correct tools and safety equipment (insulated wrenches, gloves, eye protection).
- Verify that your charging source (solar charge controller, inverter charger, etc.) is compatible with LiFePO4 batteries and set to the correct voltage and current parameters.
2. Connecting the Battery
- Terminal Connections: Use the provided M8 bolts to securely connect your battery cables to the positive (+) and negative (-) terminals. Ensure connections are tight to prevent arcing and overheating.
- Series and Parallel Connections: The battery supports up to 4P2S (4 parallel, 2 series) connections for expanding your power system. This allows for a maximum load power and energy output of 20.48kW/h. When connecting batteries in series or parallel, ensure all batteries are at a similar state of charge before connecting them.

- Avoid Extreme Temperatures: While the battery has a wide operating temperature range, prolonged exposure to extreme heat or cold outside the recommended limits can affect its lifespan.
Troubleshooting
If you encounter issues with your Humsienk LiFePO4 battery, refer to the following common troubleshooting steps:
- Battery Not Charging:
- Check all cable connections for tightness and correct polarity.
- Verify that your charger is compatible with LiFePO4 batteries and is functioning correctly.
- Ensure the ambient temperature is above 0°C (32°F) for charging. The BMS will prevent charging below this temperature. - Battery Not Discharging/No Power Output:
- Check all cable connections to the load for tightness and correct polarity.
- The BMS may have activated a protection mode (e.g., over-discharge, over-current, high/low temperature). Disconnect the load, allow the battery to rest, and then attempt to charge it to reset the BMS.
- Ensure the load is not exceeding the battery's maximum continuous discharge current (100A). - Unusual Odor or Swelling: Immediately disconnect the battery from all connections and contact customer support. Do not attempt to use or charge the battery.
For issues not resolved by these steps, please contact Humsienk customer support.
User Tips
- Proper Sizing: Always calculate your power needs carefully to ensure the battery capacity and BMS current rating are sufficient for your application. Overloading the battery can trigger BMS protection and reduce its lifespan.
- Monitor State of Charge: While LiFePO4 batteries can be discharged to 100% Depth of Discharge (DOD), monitoring the state of charge can help you plan your power usage and extend the battery's overall life.
- Parallel/Series Connections: When building a larger battery bank, ensure all batteries are from the same manufacturer, model, and ideally, purchased at the same time to ensure optimal performance and longevity. Balance the voltage of individual batteries before connecting them in parallel or series.
