3.3 Product Dimensions and Specifications
This image illustrates the physical dimensions of the DATOUBOSS 12V 100Ah LiFePO4 battery: 25.8cm (10.2in) length, 16.7cm (6.6in) width, and 21.5cm (8.5in) height. It also specifies the use of M8 terminal bolts and indicates a 100A BMS, 12.8V 100Ah capacity, 1280Wh storage, 50A maximum charging current, and 120A maximum discharging current.
4. Setup and Installation
4.1 Terminal Connections
The battery is equipped with M8 terminal bolts. Ensure all connections are clean, tight, and properly insulated to prevent arcing or short circuits. Use appropriate cable gauges for your application to handle the maximum current.
4.2 Series and Parallel Configuration
The DATOUBOSS 12V 100Ah LiFePO4 battery supports both series and parallel connections for increased voltage or capacity. It can be expanded up to 4 series and 4 parallel (4S4P) for a maximum system voltage of 51.2V and a maximum capacity of 400Ah, delivering up to 20.48kWh of energy.
- Parallel Connection: Connect batteries in parallel to increase total capacity (Ah) while maintaining the same voltage (12V). Ensure all batteries are at a similar state of charge before connecting in parallel.
- Series Connection: Connect batteries in series to increase total voltage (V) while maintaining the same capacity (Ah). Ensure all batteries are of the same model and capacity, and are at a similar state of charge before connecting in series.
Caution: Always consult a qualified electrician or refer to detailed wiring diagrams for complex series/parallel configurations to ensure safety and proper operation.
This diagram shows how multiple DATOUBOSS 12V 100Ah LiFePO4 batteries can be connected. Up to four batteries can be connected in series to achieve a 48V (51.2V) 100Ah system, or up to four batteries can be connected in parallel to create a 12V 400Ah system, allowing for flexible capacity and voltage expansion.
An example setup demonstrating the integration of DATOUBOSS LiFePO4 batteries into a solar home energy system. Solar panels charge the batteries via an MPPT controller, and an inverter converts the battery power for various household loads. This configuration supports up to 4P4S for a 51.2V 400Ah battery system, delivering up to 20.48kWh energy.
5. Operating Instructions
5.1 Charging
Use a dedicated LiFePO4 charger with appropriate voltage and current settings. The maximum recommended charging current is 50A. Overcharging with an incompatible charger can damage the battery.
This image illustrates three methods for charging the DATOUBOSS LiFePO4 battery: using a dedicated LiFePO4 charger (e.g., 14.6V 20A for 5 hours), solar panels (requiring a sunny day and typically >400W), or a generator (e.g., 20A DC-DC charger for 5 hours).
5.2 Discharging
The maximum continuous discharge current for this battery is 120A. Ensure your load does not exceed this limit to prevent damage to the battery or connected devices. The BMS will protect against overcurrent conditions.
5.3 Operating Temperature
The battery is designed for reliable operation across a wide temperature range. The recommended continuous discharge work range is from -4°F to 150°F (-20°C to 65°C).
The DATOUBOSS LiFePO4 battery is designed to operate efficiently in extreme temperature variations, with an excellent continuous discharge work range from -4°F to 150°F (-20°C to 65°C), ensuring reliable performance in diverse environments.
6. Maintenance
- Regular Inspection: Periodically check battery terminals for corrosion or loose connections. Clean terminals as needed.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place. Avoid storing in direct sunlight or extreme temperatures.
- Cleaning: Keep the battery casing clean and free from dust and debris. Use a dry cloth for cleaning.
- Avoid Deep Discharge: While LiFePO4 batteries tolerate deep cycles, avoiding excessively deep discharges can prolong overall battery life. The BMS will protect against over-discharge.
7. Troubleshooting
The built-in BMS is designed to prevent most common battery issues. If you experience problems, consider the following:
- No Power Output: Check all cable connections for tightness and proper polarity. Verify that the battery is sufficiently charged. The BMS may have activated a protection mode (e.g., over-discharge, short circuit). Disconnect the load and attempt to recharge the battery.
- Battery Not Charging: Ensure the charger is compatible with LiFePO4 batteries and is functioning correctly. Check charger connections. The BMS may have activated over-voltage or over-temperature protection.
- Reduced Performance: Ensure the battery is operating within its specified temperature range. Verify that the load is not exceeding the maximum discharge current.
If issues persist, contact DATOUBOSS customer support for assistance.
