5. Maintenance
The LOSSIGY LiFePO4 battery requires minimal maintenance due to its advanced BMS.
- Automatic Balancing: The BMS system includes high-end chips that allow for automatic balancing within the battery, reducing the need for manual intervention.
- Storage: For optimal longevity, store the battery at >50% capacity and recharge every 3 months if not in regular use.
- No Acid Maintenance: Unlike lead-acid batteries, LiFePO4 batteries do not require electrolyte checks or acid refills.
6. Troubleshooting
The integrated BMS provides comprehensive protection against various issues. If the battery stops functioning, check the following protections:
- Over-charge Protection: Prevents damage from excessive charging voltage.
- Over-discharge Protection: Prevents damage from draining the battery too low.
- Over-current Protection: Shuts off power if current draw exceeds safe limits.
- Short Circuit Protection: Immediately cuts off power in case of a short circuit.
- High Temperature Protection: Disables charging/discharging if internal temperature exceeds safe operating limits (e.g., charging high temperature protection at 149°F/65°C, discharging high temperature protection at 158°F/70°C).
- Low Temperature Protection: Disables charging/discharging if internal temperature drops below safe limits (e.g., charging low temperature protection at 32°F/0°C, discharging low temperature protection at -4°F/-20°C).
If a protection is triggered, the BMS will typically reset once the condition returns to normal. Consult the user manual for specific release conditions.
