- Generator: Use a generator with an appropriate charging output.

Figure 2: Multiple charging options for the LiFePO4 battery.
The maximum charge current is 50A. Ensure your charging source does not exceed this limit. The optimal charge temperature range is 0-45℃.
4.2. Discharge
The battery supports a continuous discharge current of ≥100A and an instantaneous discharge current of ≥200A. The end voltage (minimum discharge voltage) is 30V. Avoid discharging the battery below this voltage to prolong its lifespan.
4.3. Temperature Considerations
The battery is designed to operate within a working temperature range of -20℃ to 60℃. It features low-temperature charging protection, allowing charging in temperatures from -20℃ to 70℃, though the optimal charge temperature is 0-45℃.

5. Maintenance
MOSEWORTH LiFePO4 batteries are designed for minimal maintenance, but following these guidelines will ensure optimal performance and longevity:
- Regular Inspection: Periodically check 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% of its capacity. Store in a cool, dry place within the recommended working temperature range.
- Self-Discharge: LiFePO4 batteries have an extremely low self-discharge rate (<3% per month), significantly better than SLA batteries (>20% per month).
- Cycle Life: The battery boasts a cycle life of over 10,000 cycles, providing a long service life of approximately 10 years.

6. Troubleshooting
If you encounter issues with your MOSEWORTH LiFePO4 battery, refer to the following common problems and solutions:
- Battery Not Charging:
- Check all charging cable connections for tightness and proper polarity.
- Ensure the charger is compatible with LiFePO4 batteries and is functioning correctly.
- Verify that the ambient temperature is within the recommended charge temperature range (0-45℃). - Low Power Output:
- Check battery voltage. If below 30V, recharge immediately.
- Inspect connections for corrosion or looseness.
- Ensure the load does not exceed the continuous or instantaneous discharge current limits. - Battery Management System (BMS) Protection Triggered:
- The built-in BMS protects against overcharge, overdischarge, overcurrent, short circuit, and high/low temperatures. If the battery stops functioning, the BMS may have activated.
- Disconnect the load/charger, allow the battery to rest, and then attempt to restart or recharge. If the issue persists, contact support. - Unusual Odor or Swelling:
- Immediately disconnect the battery from all loads and chargers.
- Move the battery to a safe, well-ventilated area away from flammable materials.
- Do NOT attempt to use or charge the battery. Contact customer support.

- Parallel/Series Connections: While the upgraded BMS supports series/parallel connections, it is highly recommended to consult a professional or refer to detailed wiring diagrams for such setups to ensure safety and optimal performance.
- Initial Charge: Although batteries often come partially charged, it's good practice to fully charge the battery before its first use to calibrate the BMS and ensure maximum capacity.
- Monitor Voltage: For critical applications, consider installing a battery monitor to keep track of voltage, current, and state of charge, especially to avoid deep discharge.
- Ventilation: Even though LiFePO4 batteries are safer than lead-acid, good ventilation is always recommended, especially in enclosed spaces, to dissipate any heat generated during operation.
