2. Safety Information
Please read and understand all safety instructions before operating the battery. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.
- General Safety: KEEP OUT OF REACH OF CHILDREN. In case of ingestion of any battery components, seek medical attention immediately.
- Battery Management System (BMS): The integrated 100A BMS provides comprehensive protection against overcharge, over-discharge, overcurrent, and short-circuit conditions.
- Temperature Protection: The BMS includes a high-temperature cut-off to prevent charging above 158°F (70°C) and automatically cuts off charging in low-temperature conditions (below 32°F/0°C) to prevent irreversible damage. Discharge is safe down to -4°F (-20°C).
- Charging: Only use a compatible lithium battery charger designed for LiFePO4 batteries. Using an incompatible charger can damage the battery and pose a safety risk.
- Connections: Ensure all connections are secure and properly insulated to prevent short circuits. Do not connect the battery in reverse polarity.
- Environment: Do not expose the battery to fire, direct sunlight, or extreme temperatures outside the specified operating range. Do not immerse the battery in water.
- Modification: Do not disassemble, puncture, or modify the battery in any way. This can lead to dangerous situations and voids the warranty.

4. Setup and Installation
Proper setup is crucial for the performance and safety of your battery. Always ensure you have the correct tools and safety equipment before beginning installation.
4.1 Initial Inspection
- Unpack the battery and inspect it for any visible damage. If damage is found, contact customer support immediately.
- Verify that all components listed in the packaging are present.
4.2 Connection Guidelines
- Single Battery Connection: Connect the positive (+) terminal of the battery to the positive input of your load/inverter and the negative (-) terminal to the negative input.
- Series Connection (for higher voltage): To increase voltage, connect batteries in series. Connect the positive terminal of one battery to the negative terminal of the next. Ensure all batteries are of the same capacity and type. The Humsienk 12V 314Ah battery supports up to 4S (51.2V) configurations.
- Parallel Connection (for higher capacity): To increase capacity, connect batteries in parallel. Connect all positive terminals together and all negative terminals together. Ensure all batteries are of the same capacity and type. The Humsienk 12V 314Ah battery supports up to 4P (1256Ah) configurations.
- Combined Series-Parallel (4S4P): For maximum energy storage (up to 63.48kWh), you can configure the batteries in a 4S4P arrangement. Consult a qualified electrician for complex wiring setups.
- Cable Sizing: Use appropriately sized cables and fuses for your application to prevent overheating and ensure safety.
- Tighten Connections: Ensure all terminal connections are tight to prevent resistance and heat buildup.
4.3 Charger Compatibility
Use only a dedicated LiFePO4 battery charger with appropriate voltage and current ratings. Do not use chargers designed for lead-acid batteries, as this can damage the LiFePO4 battery.
5. Operation
5.1 Charging
- Connect your LiFePO4 compatible charger to the battery terminals.
- Ensure the charging temperature is within the range of 32°F (0°C) to 149°F (65°C). The BMS will automatically cut off charging if temperatures fall outside this range.
- Monitor the charging process. The BMS will prevent overcharging.
5.2 Discharging
- The battery can be discharged within the temperature range of -4°F (-20°C) to 158°F (70°C).
- The 100A BMS will protect against overcurrent and over-discharge, ensuring the battery operates within safe limits.
- The battery provides 4019Wh of energy, capable of powering various appliances. For example, it can power a 100W TV for 40 hours, a 200W bread maker for 20 hours, a 500W microwave for 8 hours, or a 700W air conditioner for 4 hours.
6. Maintenance
The Humsienk LiFePO4 battery is designed to be largely maintenance-free due to its advanced BMS and robust cell chemistry.
- Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals if necessary and ensure they are tight.
- Cleaning: Keep the battery clean and free from dust and debris. Use a dry cloth for cleaning. Do not use solvents or abrasive cleaners.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% of its capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Deep Discharge: While the BMS protects against over-discharge, it is good practice to avoid leaving the battery in a fully discharged state for prolonged periods.
7. Troubleshooting
If you encounter issues with your Humsienk LiFePO4 battery, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incompatible charger, loose connections, BMS protection triggered (low/high temperature, over-discharge) | Ensure charger is LiFePO4 compatible. Check all cable connections. Move battery to a suitable temperature environment. If over-discharged, a specialized charger might be needed to reactivate. |
| Battery not providing power | BMS protection triggered (over-discharge, overcurrent, short-circuit), low state of charge, loose connections | Check battery voltage. Recharge if low. Reduce load if overcurrent. Inspect for short circuits. Check all cable connections. |
| Battery overheating | Excessive load, high ambient temperature, internal fault | Reduce load. Move battery to a cooler environment. If problem persists, discontinue use and contact support. |
| Unusual odors or swelling | Internal damage, severe overcharge/over-discharge | Immediately disconnect the battery from all loads and chargers. Move to a safe, well-ventilated area. Do NOT attempt to use or repair. Contact customer support. |
If you are unable to resolve an issue using these steps, please contact Humsienk customer support for assistance.
