Charging & Safety Guidelines:
Always follow these guidelines for safe operation and maximum cycle life:

• Use only a charger compatible with the charging specifications of the battery.
• Charge at standard current rate for optimal cycle life; max current rate for faster charging.
• Never charge above the maximum charging voltage to avoid overcharge.
• Do not discharge below the discharging cutoff voltage to avoid overdischarge and prevent permanent damage.
• Do not discharge above the current rating. Exceeding these limits may trigger BMS protection or cause permanent damage to the battery cells.
• Operate the battery within the specified environmental conditions (temperature, humidity, and ventilation).
• Keep the battery away from fire, open flames, radiators, and other heat sources.
• Do not expose the battery to direct sunlight for extended periods during operation.
• Store at 20±5°C for extended periods to maximize longevity. Keep humidity below 85% during storage.
• Do not disassemble, puncture, or expose to fire.

Shipping & Handling Instructions:
To ensure safe transport and compliance with international regulations, please note the following:

• The battery can be shipped by air, sea, and ground transport — subject to applicable dangerous goods regulations for lithium batteries.
• UN38.3 Compliant — The battery has been tested and certified in accordance with UN38.3 for safe air and sea transport.
• Package Properly — Use only UN-certified packaging for lithium batteries. Ensure terminals are protected against short circuits and pack securely to prevent movement during transit.
• State of Charge (SoC) — For transport, maintain the battery at ≤30% state of charge as required by IATA and IMDG regulations.
• Labeling — Packages must display the appropriate lithium battery handling labels and include emergency contact information.
• Documentation — Ensure the shipping declaration includes the proper UN number (e.g., UN3480 for lithium-ion batteries) and your dangerous goods transport documents.
• Prohibited Shipments — Damaged, defective, or recalled batteries are strictly prohibited from transport.

Storage & Long-Term Maintenance:
To ensure maximum service life and maintain optimal cell health, please follow these guidelines for extended storage:

• Optimal Temperature — Store the battery at a stable temperature between 15°C and 25°C (ideal: 20±5°C). Avoid exposure to extreme heat, direct sunlight, or freezing conditions.
• Recommended Humidity — Keep storage environment humidity below 85% to prevent moisture ingress and potential damage to the battery cells and BMS components.
• Partial Charge for Storage — For extended storage (longer than 3 months), maintain the battery at approximately 50%–60% state of charge (around the nominal voltage). Do not store fully charged or fully depleted — both conditions accelerate capacity degradation.
• Periodic Maintenance Cycle — For batteries stored over six months or longer, perform at least one full charge/discharge cycle every six months to maintain cell health. This helps recalibrate the BMS, balance the cells, and prevent voltage drift that can lead to capacity loss.
• Inspect Before Use — Before returning a stored battery to service, inspect for any signs of swelling, leakage, or damage. If the battery voltage is below the discharging cutoff voltage, it has been over-discharged and should not be reused.

💡 Why cycle stored lithium batteries? Cells naturally self-discharge over time, and the built-in BMS circuit consumes a small amount of current even when idle. In multi-cell packs, slight variations in self-discharge rates between cells can gradually cause voltage imbalances. A maintenance cycle keeps the cells electrochemically active, balances the pack, and prevents capacity loss or degradation.
