5. Setup and Installation
5.1 Initial Inspection
Before installation, carefully inspect the battery for any signs of damage. Ensure all terminals are clean and free of debris.
5.2 Connecting the Battery
Use the provided M8 screws to secure the battery connections. Ensure all connections are tight to prevent arcing and ensure optimal performance.
⚠️ IMPORTANT: Always connect the positive (+) terminal first, then the negative (-) terminal. When disconnecting, disconnect the negative (-) terminal first, then the positive (+).
5.3 Series and Parallel Connections
The Humsienk LiFePO4 battery supports up to 4S4P configuration, allowing for a maximum system of 51.2V 1200Ah (61.44kWh). When connecting multiple batteries:
- Parallel Connection: Connect positive terminals together and negative terminals together to increase total capacity (Ah) while maintaining the same voltage (V).
- Series Connection: Connect the positive terminal of one battery to the negative terminal of the next to increase total voltage (V) while maintaining the same capacity (Ah).
⚠️ CAUTION: Ensure all batteries in a series or parallel bank are of the same type, capacity, and state of charge before connecting. Consult a qualified electrician for complex installations.

6. Operation
6.1 Charging the Battery
The battery can be charged using three primary modes:
- Dedicated LiFePO4 Charger
- Solar Panel with MPPT Charge Controller
- Generator
⚠️ IMPORTANT: Ensure your charger is compatible with LiFePO4 batteries and provides the correct voltage and current. Do not exceed the maximum charging current of the 200A BMS.
6.2 Bluetooth APP Monitoring
Your Humsienk LiFePO4 battery features an integrated Bluetooth 5.0 module for real-time monitoring via a smartphone application. Follow these steps:
- Download: Search for the "Humsienk" or "LiFePO4 Battery Monitor" app on your smartphone's app store and install it.

7. Maintenance
7.1 General Care
- Keep the battery clean and dry.
- Regularly check terminal connections for tightness and corrosion.
- Avoid exposing the battery to extreme temperatures outside its operating range.
7.2 Storage
For long-term storage, ensure the battery is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place. Disconnect it from all loads and charging sources. Periodically check the voltage and recharge if necessary to prevent deep discharge.
7.3 BMS Protection
The built-in BMS is maintenance-free and automatically manages the battery's safety features. It will protect against over-charge, over-discharge, over-current, short-circuit, and extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, charger incompatible, BMS protection activated (over-discharge, low-temp cut-off) | Check charger connection. Ensure charger is LiFePO4 compatible. If BMS is active, address the underlying issue (e.g., bring battery to warmer temperature for charging). |
| No power output | Battery discharged, loose connections, BMS protection activated (over-discharge, over-current, short-circuit) | Check battery charge level. Tighten all connections. If BMS is active, remove the load, check for short circuits, and allow the battery to reset. |
| Bluetooth connection issues | Out of range, Bluetooth disabled on phone, app issue | Move closer to the battery. Ensure Bluetooth is enabled. Restart the app or your phone. |
| Battery feels hot during operation/charging | Overloading, high ambient temperature, internal fault | Reduce load or charging current. Ensure adequate ventilation. If overheating persists, disconnect immediately and contact support. BMS should trigger high-temperature cut-off. |
9. User Tips
- Optimal Performance: For maximum lifespan, avoid consistently discharging the battery to 0% DOD. Aim for shallower discharges when possible.
- Cold Weather Charging: The BMS will prevent charging below 0°C (32°F). If operating in cold environments, ensure the battery is warmed up before attempting to charge.
- App Monitoring: Regularly check the Humsienk app to monitor battery health, voltage, and temperature, especially during initial setup and heavy use.
- Connection Quality: Always use high-quality cables and ensure secure, tight connections to minimize resistance and maximize efficiency.
