5. Maintenance

Proper maintenance ensures optimal performance and extends the lifespan of your LiFePO4 battery. The built-in BMS (Battery Management System) provides protection against over-voltage, over-load, and over-temperature.

5.1 Correct Charging Practices

For new batteries, it is recommended to perform 3 or more full charge/discharge cycles to achieve optimal performance.
Always use a charger from a reputable manufacturer and follow its instructions. When using a fast charger, if the indicator light shows 90% full, you can wait for the battery to fully charge.
Charge the battery at room temperature (between 0°C and 60°C). Avoid covering the battery during charging to prevent overheating.

5.2 Scientific Discharge Practices

Avoid excessive discharge current: High discharge currents can cause internal heating and permanent damage. Larger discharge currents lead to smaller discharge capacity and faster voltage drops.
Never over-discharge: Do not discharge the battery below 80% of its capacity to protect it. Over-discharge can lead to irreversible chemical reactions and damage the battery. The internal protection circuit will stop discharge before voltage drops to damaging levels (e.g., below 2.7V).
Avoid high-power discharge: The voltage attenuation of a lithium battery decreases faster with increasing discharge rate. Small rate discharge is generally better than high rate discharge for battery longevity.

5.3 Proper Storage of Lithium Batteries

Optimal Temperature: Store the battery between 4°C and 35°C. Avoid exposure to extreme high or severe cold temperatures.
Long-term Storage: For batteries not used for extended periods, perform a charge and discharge cycle (similar to "activation") and a power calibration once a month. This prevents passivation of battery electrodes. Ideally, store the battery at approximately 50% charge.
Environmental Conditions: Do not store in areas with strong static electricity or magnetic fields, as this can damage the battery's safety protection device.
Abnormalities: If the battery emits a peculiar smell, heats up, discolors, deforms, or shows any other abnormality during use, storage, or charging, immediately disconnect it from the device or charger and cease use.
Disposal: Electrodes of discarded batteries should be wrapped with insulating paper to prevent fire and explosion hazards.

6. Troubleshooting

This section provides guidance on common issues and their potential solutions. The built-in BMS offers various protections and status indicators to help diagnose problems.

6.1 BMS Status Indicators

Refer to the table below for interpreting the RUN, ALM, and SOC LED indicators and their corresponding states:

BMS status indicator table for RUN, ALM, and SOC LEDs, describing various states. — BMS interface pin definition and status indicator table for RUN, ALM, and SOC LEDs, describing various states (Shut down, Standby, Normal, Warning, Over Charge Protection, Over temperature/Over current/Fail protection, Over Discharge Protection, Fault).

6.2 General Troubleshooting Tips

No Power/Display: Ensure the power button is pressed, and check all cable connections for secure fit. Verify the input voltage from the charging source or inverter.
Alarm LED (ALM) On: Consult the BMS status indicator table to identify the specific alarm condition (e.g., low voltage, over-temperature, over-current). Address the underlying cause as indicated.
Battery Not Charging: Check the charger connection and ensure it is functioning correctly. Verify the charging temperature is within the specified range (0-60°C).
Reduced Capacity/Lifespan: Review maintenance practices, especially regarding charging/discharging habits and storage conditions. Ensure the battery is not consistently over-discharged or subjected to high-power discharge.
Unusual Odor, Heat, or Deformation: Immediately disconnect the battery from all power sources and loads. Do not attempt to operate or charge the battery. Contact customer support.
