Precautions
When using the battery module, it's important to keep the following precautions in mind:
Proper Handling: Handle the battery module with care to avoid physical damage or punctures that could lead to safety hazards.
Charging: Only use chargers recommended by the manufacturer to prevent overcharging, which can damage the cells and pose safety risks.
Discharging: Avoid deep discharges, as they can reduce the overall lifespan of the battery. Use within the specified voltage range.
Temperature: Operate the battery within the recommended temperature range. Extreme heat or cold can impact performance and safety.
Ventilation: Provide adequate ventilation when charging or discharging to prevent excessive heat buildup.
Battery Management System (BMS): Ensure the BMS is functioning properly to monitor cell balance, temperature, and prevent overcharging or over-discharging.
Physical Protection: Protect the battery from physical impacts, moisture, and exposure to flammable materials.
Storage: If storing the battery for an extended period, ensure it's at a partial charge (around 50%) and in a cool, dry place.
Compatibility: Use the battery module in systems designed to handle its specifications to prevent overloading or other compatibility issues.
Maintenance: Regularly inspect and maintain connections, wiring, and the BMS to ensure safe and reliable operation.
Authorized Service: Seek professional assistance from authorized technicians for any maintenance, repair, or modification.
Always refer to the manufacturer's guidelines and documentation for specific usage instructions and safety recommendations.
