If the battery will not be used for an extended period, store and maintain it as follows:

• Fully charge the battery, then switch off the circuit breaker and the ON/OFF switch (BMS off).
• Check the battery voltage at least every 3 months. If the voltage is below 51V, recharge promptly.
• Store the battery in a dry, clean, well-ventilated indoor location, away from direct sunlight and rain, and away from high-temperature heat sources, open flames, and flammable or explosive materials
• During storage, the battery should be completely disconnected from external equipment, and all indicators should be off
• The floor of the storage area should be level and solid, and qualified fire protection facilities (e.g., dry powder extinguishers, fire sand) should be provided
• Handle with care during transport and storage; dropping, collision, tipping, side placement, and tilting are prohibited

danger

Battery damage caused by failure to recharge in time is not covered by the warranty. Long-term storage without recharging will over-discharge the battery, causing irreversible capacity loss or even scrapping the battery.

Appendix II: Emergency Handling

danger

In emergencies such as electric shock, fire, or electrolyte leakage, ensure personal safety first, evacuate personnel promptly, and call the appropriate emergency numbers. Do not operate damaged equipment without professional inspection and qualified testing.

Electric Shock

• Cut off the power immediately, provided your own safety is ensured
• Use an insulated object to separate the victim from the power source, administer first aid including cardiopulmonary resuscitation (CPR), and immediately call the emergency number
• Preserve the accident scene for investigation and evidence collection
• After the accident, the system must be inspected by professionals and may only be returned to service after repair or replacement and passing testing

Fire or Explosion Risk

• Evacuate the area immediately and call the fire department; stay away from smoke produced by burning. Only dry powder extinguishers may be used to fight the fire; liquid extinguishers are strictly prohibited
• Cut off the upstream power supply, provided your own safety is ensured, and wear respiratory protective equipment
• Isolate the accident area where it is safe to do so, preventing unauthorized personnel from entering; post-incident handling must be completed by professionals

Electrolyte Leakage and Chemical Hazards

• In the event of electrolyte leakage, evacuate personnel immediately and notify the relevant personnel; the leaked material must be safely collected and disposed of by professionals
• Burning or damaged batteries may release toxic gases; evacuate to a safe area immediately. If personnel are exposed or injured, seek medical attention immediately
• When handling leaked material, wear respiratory protective equipment, protective clothing, and other safety gear

Mechanical Injury

• If the equipment tips over, the battery falls, or parts come loose, cut off the power immediately and stop the system
• If anyone is injured, administer first aid such as stopping bleeding and bandaging, and immediately call the emergency number
• If abnormalities such as odor, damage, smoking, or fire are observed, evacuate immediately and raise the alarm; the abnormal battery should be moved by professionals to an open, safe area, left undisturbed for at least 1 hour, and its temperature monitored

Natural Disasters

• In the event of natural disasters such as earthquakes, typhoons, floods, or wildfires, cut off the power immediately and stop the system
• If the system is flooded or submerged, do not touch it and stay away from the waterlogged area. Flooded batteries must not be used again; contact a professional recycling agency for scrapping
• Before a wildfire approaches, a firebreak may be established around the system, and fire equipment such as extinguishers and fire sand should be prepared
