Usage Notices
Charging Notices:
- Use a dedicated LiFePO₄ battery charger for charging
- Do not use chargers designed for lead-acid, Ni-MH, or other battery chemistries unless they are compatible with LiFePO₄ charging requirements
- Avoid overcharging or leaving the battery connected to the charger for extended periods after it is fully charged
- Charge the battery within the recommended temperature range to maintain optimal performance
Discharging Notices:
- Do not exceed the specified continuous discharge current or maximum discharge current
- Avoid deep discharge below the battery protection voltage, as it may affect battery lifespan
- Stop using the battery immediately if abnormal conditions such as swelling, leakage, unusual heat, or odor occur
Temperature & Environmental Notices:
- Avoid exposing the battery pack to extreme temperatures, direct sunlight, fire, or water
- For applications in extremely cold or hot environments, customized solutions should be considered
- Keep the battery away from corrosive substances and high-humidity conditions
Maintenance Notices:
- Regularly inspect the battery pack, connectors, and cables for damage or abnormal conditions
- Keep terminals clean and dry to ensure stable electrical contact
- Do not disassemble or modify the battery pack without professional guidance
