⚠️ Please mind potential fire risk and strictly follow the instruction manual for charging and storage. For disposal, please check your local authority's website for more information and dispose of the lithium-ion battery safely in accordance with the applicable legal requirements.
3. Setup and Connection
3.1. How to Connect Battery
Ensure all batteries intended for connection meet the following criteria:
- Batteries must have the same Voltage (V), same Capacity (Ah), and be of the same type (Lithium Iron Phosphate (LiFePO4)).
- Due to potential variations in built-in Battery Management Systems (BMS) between brands, it is recommended to use batteries from the same brand for connection.
For optimal performance, fully charge all batteries before connecting them.
3.2. Series and Parallel Connection
The MFUZOP LiFePO4 batteries support both series and parallel connections to expand capacity or voltage. Refer to the diagram below for proper connection methods.
Series Connection: Connect batteries one by one in series (up to 4 batteries) to increase voltage.
Parallel Connection: Connect batteries in parallel (up to 4 batteries) to increase capacity.
Secure all cable connections between the cable lugs and terminals. Ensure all battery interconnect cables are of the same wire gauge (AWG) and length, and ideally from the same brand, to prevent unbalanced charge and discharge performance due to inconsistent impedance.
3.3. Cable Sizing
When determining the appropriate cable size (AWG) for your system, consider the following factors:
- The size of the electrical load you intend to power.
- The distance between the electrical load and your batteries.
Refer to the following charts for guidance:
Cables for Controller to Battery
| Solar Input Current | 5A | 10A | 20A | 30A | 40A | 60A |
|---|---|---|---|---|---|---|
| Wire Cross Section Area (mm²) | 1.5 | 2.5 | 5 | 8 | 10 | 12 |
| Wire AWG | 15 | 13 | 10 | 8 | 7 | 6 |
Cables for Inverter to Battery
| Cable Size | Copper Conductor Diameter (inches) | Maximum Amperage |
|---|---|---|
| 6 AWG | 0.20 | 115 |
| 4 AWG | 0.23 | 150 |
| 2 AWG | 0.30 | 205 |
| 1/0 AWG | 0.37 | 285 |
| 2/0 AWG | 0.43 | 325 |
| 4/0 AWG | 0.56 | 440 |
4. Operation
4.1. Applications
MFUZOP LiFePO4 batteries are versatile and suitable for a wide range of applications, including:
- RV (Recreational Vehicles)
- Marine Boats
- Trolling Motors
- Home Energy Storage
- Solar Power Systems (Off-Grid and Grid-Tied)
4.2. Charging Methods
Your MFUZOP LiFePO4 battery can be charged using various methods:
- Dedicated LiFePO4 Charger: Provides optimal charging parameters.
- Solar Panels: Ideal for off-grid and renewable energy setups. Actual charging time may vary based on sunlight conditions.
- Generator: Can be used with an appropriate DC-DC charger.
4.3. Powering Appliances
The battery can power various household appliances and devices. When connecting multiple batteries in parallel, the theoretical maximum power is significantly increased. However, consider the peak power requirements of appliances, especially those with AC motors (e.g., air conditioners, water pumps), which can draw double or more of their rated power. Consult appliance manufacturers for accurate peak power data.
4.4. Temperature Performance
MFUZOP LiFePO4 batteries are designed to handle extreme temperature fluctuations, operating effectively from -4°F to 150°F (-20°C to 65°C). The battery features excellent continuous discharge performance across this range.
5. Maintenance and Storage
5.1. How to Store Battery
To ensure the longevity and optimal performance of your battery during storage:
- Keep the battery charged to at least 30%-50% of its capacity.
- If not in use, it is recommended to charge the battery every 6 months to prevent over-discharge.
6. Troubleshooting
Your MFUZOP LiFePO4 battery is equipped with a Smart BMS (Battery Management System) that provides multiple levels of protection. This system helps prevent common issues and ensures safe operation.
The BMS includes protections against:
- Overcharge
- Over-discharge
- Overcurrent
- Short circuit
- Temperature (high/low)
- Reverse polarity
If the battery is fully discharged at a continuous rate, it cannot be recharged immediately at half capacity. This will trigger high-temperature charging protection. Allow the battery to cool down before attempting to recharge.
