1.Temperature sensitivity: LIFePo4 batteries may be affected by extreme temperatures (too high or too low) in their performance and life. Too high temperatures may cause the battery to overheat, while too low temperatures may reduce the battery's discharge capacity.

2. Improper charging: If the charger is not suitable for LIFePo4 batteries, it may cause inefficient charging or battery damage. Using improper charging voltage and current will affect the health of the battery.

3. Battery Management System (BMS) Failure: BMS is responsible for monitoring the status of the battery, including voltage, temperature, and charge status. If the BMS fails, it may cause the battery to be overcharged, over-discharged, or abnormally temperature.

4. Cycle life: Although LIFePo4 batteries have a long cycle life, frequent deep discharge and recharge will still affect their service life. Maintaining the proper depth of charge and discharge is the key.

5. Self-discharge: The self-discharge rate of LIFePo4 batteries is relatively low, but if they are not used for a long time, self-discharge may still occur, causing the battery power to decline.

6. Physical damage: The battery may be subjected to physical shock or vibration during forklift operation, causing internal damage or short circuits.

7. Battery aging: The capacity and performance of the battery will gradually decrease with the increase of use time, and may need to be replaced.

8. Compatibility issues: In some cases, LIFePo4 batteries may not be compatible with specific models of forklifts, causing performance issues.
