4.3 Discharge and Charging Limits

The battery's 100A BMS allows for efficient charging up to 30A and an instantaneous discharge current of ≤100A. The operating voltage range is 10V to 14.6V. Always operate within these limits to prevent damage and ensure safety.

5. Maintenance

5.1 Charging Recommendations

For optimal battery life, it is recommended to fully charge the battery after each significant discharge. Avoid leaving the battery in a deeply discharged state for extended periods.

5.2 Storage Guidelines

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. The battery storage period is 90% power for 6 months.

5.3 Cleaning

Keep the battery casing and terminals clean and free of dust and debris. Use a dry cloth for cleaning. Do not use abrasive cleaners or solvents.

5.4 Lifespan

The GuaiGLong LiFePO4 battery is designed for durability, offering a lifespan exceeding 8000 cycles under optimal conditions.

6. Troubleshooting

The built-in 100A Battery Management System (BMS) provides comprehensive protection against various issues. If you encounter problems, refer to the BMS protection features below.

Image 6.1: Diagram illustrating the various protection features of the integrated 100A BMS, including safeguards against short circuits, overcharge, low/high temperature, over-discharge, auto-cell balance, and over-current.

• Short Circuit Protection: The BMS will automatically cut off power in case of a short circuit.
• Overcharge Protection: Prevents the battery from being charged beyond its safe voltage limit.
• Low/High Temperature Protection: The battery will cease operation if temperatures fall outside the safe operating range (Charge at 0°C-45°C, Discharge at -20°C-60°C).
• Over-Discharge Protection: Prevents the battery from being discharged below its safe voltage limit, preserving battery health.
• Auto-Cell Balance: Helps maintain balanced voltage across individual cells for improved performance and longevity.
• Over-Current Protection: Shuts down the battery if the discharge current exceeds safe limits.

If the battery enters a protected state, disconnect the load or charger, wait a few minutes, and then attempt to reactivate the BMS as described in Section 3.3 if necessary. If problems persist, contact customer support.
