2. Safety Information

Adherence to the following safety guidelines is crucial to prevent injury and damage to the battery.

• Do not short-circuit the battery terminals. This can cause severe damage to the battery and pose a fire hazard.
• Use only compatible LiFePO4 chargers. Using chargers designed for other battery chemistries (e.g., lead-acid) can damage the battery and void the warranty.
• Avoid extreme temperatures. Do not charge the battery below 0°C (32°F) or above 50°C (122°F). Do not discharge the battery below -20°C (-4°F) or above 55°C (131°F).
• Do not disassemble, puncture, or modify the battery. This can lead to internal damage, leakage, or fire.
• Keep out of reach of children.
• Proper disposal. Dispose of the battery according to local regulations. Do not dispose of in household waste.
• Ventilation. Ensure adequate ventilation when charging or operating the battery in enclosed spaces.

3. Product Features

The DC HOUSE 12V 6Ah Mini Lithium LiFePO4 Deep Cycle Battery offers several advanced features:

• Extended Lifespan: Designed for over 4000 deep charge/discharge cycles, providing a significantly longer operational life compared to traditional lead-acid batteries.
• Integrated BMS Protection: Features a built-in Smart Battery Management System (BMS) that protects against over-charging, over-discharging, over-current, and short-circuiting, enhancing safety and battery longevity.
• Lightweight Design: Weighs approximately 1.65 lbs, making it considerably lighter than comparable lead-acid batteries.
• Wide Operating Temperature Range: Supports charging from 0°C to 50°C and discharging from -20°C to 55°C.
• Flexible Expansion: Can be connected in series or parallel for increased voltage or capacity. Up to 8 batteries can be connected in total (e.g., 2P2S, 2P3S, 2P4S, 3P2S, 4P2S).

5. Setup and Installation

5.1 Physical Dimensions and Terminals

The battery features F2 terminals for connection. Ensure your cables and connectors are compatible.

5.2 Series and Parallel Connection

This battery supports both series and parallel connections to achieve higher voltage or capacity. A maximum of 8 batteries can be connected in total. When connecting multiple batteries:

• For Series Connection: Connect the positive terminal of one battery to the negative terminal of the next. This increases the total voltage while maintaining the same capacity. Ensure all batteries have the same voltage and capacity before connecting in series.
• For Parallel Connection: Connect positive terminals together and negative terminals together. This increases the total capacity while maintaining the same voltage. Ensure all batteries have the same voltage and capacity before connecting in parallel.
• Mixed Configurations: Configurations like 2P2S (2 parallel strings of 2 series batteries) are possible. Always ensure all batteries are of the same model and state of charge before connecting.

6. Charging

Proper charging is essential for the lifespan of your LiFePO4 battery. Always use a charger specifically designed for LiFePO4 batteries.

• Recommended Charging Temperature: Charge the battery within the range of 0°C to 50°C (32°F to 122°F). Charging outside this range can reduce battery life and performance.
• Charging Methods: The battery can be charged using a dedicated LiFePO4 charger or a compatible solar panel kit.

7. Operation

The DC HOUSE 12V 6Ah LiFePO4 battery is versatile and suitable for various applications requiring deep cycle power.

• Discharging Temperature: The battery can be safely discharged in temperatures ranging from -20°C to 55°C (-4°F to 131°F).
• Applications: Ideal for energy storage, outdoor applications (e.g., fish finders), lighting systems, power wheels, children's cars, lawn mowers, solar panel systems, and as a backup power supply.
• Important Note: This battery is not designed for use as a motor starter battery.

8. Maintenance

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

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean as necessary.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid Deep Discharge: While LiFePO4 batteries tolerate deep discharge, consistently avoiding full discharge cycles can further extend their life. The built-in BMS will protect against over-discharge.
• Recharge Periodically: For long-term storage, recharge the battery every 3-6 months to prevent self-discharge below critical levels.

9. Troubleshooting

If you encounter issues with your battery, consider the following common troubleshooting steps:

• Battery Not Charging:
  • Ensure the charger is specifically designed for LiFePO4 batteries and is functioning correctly.
  • Check all connections between the charger and the battery for secure contact.
  • Verify that the ambient temperature is within the recommended charging range (0°C - 50°C).
  • The BMS may have activated protection mode due to extreme conditions. Allow the battery to return to normal operating temperature.
• Low Power Output:
  • Confirm the battery is fully charged.
  • Check for loose or corroded connections to the load.
  • Ensure the load's power requirements do not exceed the battery's maximum continuous discharge current (6A).
  • Verify the ambient temperature is within the recommended discharging range (-20°C - 55°C).
• Battery Overheating:
  • Immediately disconnect the battery from the charger or load.
  • Allow the battery to cool down in a well-ventilated area.
  • Review charging and discharging parameters to ensure they are within specifications. The BMS should prevent severe overheating.
