2. Safety Information
WARNING: Failure to follow these safety instructions may result in electric shock, fire, serious injury, or death.
- Always wear appropriate personal protective equipment (PPE) including safety glasses and insulated gloves when handling batteries.
- Do not short-circuit the positive and negative terminals. This can cause severe damage to the battery and pose a fire hazard.
- Do not disassemble, modify, or attempt to repair the battery without authorization. Internal components are not user-serviceable.
- Keep the battery away from fire, heat sources, and flammable materials.
- Do not immerse the battery in water or expose it to excessive moisture. The battery has an IP65 waterproof rating, but direct immersion is not recommended.
- Use only chargers specifically designed for LiFePO4 batteries that match the output voltage of this lithium battery.
- Ensure proper ventilation when charging or discharging the battery.
- Keep out of reach of children.
- In case of fire, use a Class D fire extinguisher or copious amounts of water.
Image 2.1: Built-in BMS Protection Features.
The DATOUBOSS LiFePO4 Battery includes a built-in 100A Battery Management System (BMS) to protect against common issues such as over-voltage, under-voltage, over-current, over-temperature, and short-circuit conditions, enhancing safety and reliability.
3. Product Features
- Integrated BMS: Equipped with a 100A BMS for protection against over-voltage, overload, overcharge, over-discharge, overcurrent, short circuit, and high temperature.
- Expandable Capacity: Supports series and parallel connections up to 4P4S, allowing for a 48V (51.2V) 400Ah Li-Ion battery pack with up to 20.48kWh energy.
- High Performance & Safety: Constructed with automotive-grade LiFePO4 cells, UL-certified for safety, and features an IP65 waterproof rating.
- Lightweight & Compact: Weighs approximately 10.92kg, which is significantly lighter than comparable lead-acid batteries, facilitating easier installation and portability.
- Wide Application: Suitable for various uses including RVs, solar energy systems, trolling motors, marine applications, home backup power, and off-grid setups.
- Extended Cycle Life: Offers 4000-15000+ deep charge/discharge cycles, providing a long operational lifespan.
- Temperature Tolerance: Designed to operate effectively in a wide temperature range, from -4°F to 150°F (-20°C to 65°C).

5. Setup and Installation
5.1 Initial Inspection
Before installation, visually inspect the battery for any physical damage. Ensure terminals are clean and free of corrosion.
5.2 Connection Guidelines
Ensure all connections are secure and properly insulated to prevent short circuits. Use appropriate gauge cables for your application.
- Single Battery Connection: Connect the positive terminal of the battery to the positive input of your load/charger and the negative terminal to the negative input.
- Parallel Connection (for increased capacity): Connect positive terminals together and negative terminals together. Ensure all batteries are at a similar state of charge before connecting in parallel.
- Series Connection (for increased voltage): Connect the positive terminal of one battery to the negative terminal of the next battery. This battery supports up to 4 batteries in series (4S) for a 48V system.
- Series-Parallel Connection (4P4S): For maximum capacity and voltage, up to 16 batteries can be configured in a 4P4S arrangement to achieve a 48V 400Ah system (20.48kWh). Consult a qualified electrician for complex setups.

6. Operating Instructions
6.1 Charging the Battery
Use a compatible LiFePO4 battery charger. The recommended charge voltage is 14.4V-14.6V. The maximum charge current is 50A. Avoid overcharging or using chargers not designed for LiFePO4 batteries.

6.2 Discharging the Battery
The maximum continuous discharge current is 100A, with a peak discharge current of 120A. The BMS will protect the battery from over-discharge. Ensure your load does not exceed the battery's rated discharge current.
6.3 Storage
For long-term storage, charge the battery to approximately 50% of its capacity (around 13.2V). Store in a cool, dry place, away from direct sunlight and extreme temperatures. Periodically check the battery voltage during storage and recharge if necessary.
7. Maintenance
- Regularly inspect battery terminals for cleanliness and tightness. Clean any corrosion with a wire brush and baking soda solution, then rinse with distilled water and dry thoroughly.
- Ensure the battery is kept within its recommended operating temperature range.
- Avoid fully discharging the battery frequently, as this can reduce its overall lifespan, although the BMS provides protection.
- Do not expose the battery to physical shock or vibration.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger, loose connections, BMS protection activated (over-discharge) | Verify charger compatibility and connections. If BMS is active, try a low-current charge to reactivate. |
| Battery not discharging | Overload, short circuit, BMS protection activated (over-charge, over-discharge, over-current) | Reduce load, check for short circuits. Allow battery to rest if BMS has tripped due to over-discharge. |
| Reduced capacity/runtime | Aging battery, extreme operating temperatures, improper charging habits | Ensure proper charging. Operate within recommended temperature range. If battery is old, consider replacement. |
| Unusual heat during operation/charging | Overload, internal fault, poor ventilation | Immediately disconnect the battery. Check for overload or short circuits. Ensure adequate ventilation. If problem persists, discontinue use and contact support. |
