Precautions：
•No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
• Please check the orientation of the positive and negative terminals before packaging.
•Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuit.
• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).
• Do not place the battery in direct sunlight or a heat source.
• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.
Important Notes：
1. Do not charge beyond the maximum charging rate.
2. Do not disassemble or modify the battery.
3. Do not throw or hit the battery.
4. Do not pierce the battery with sharp objects (such as nails, knives, pens, electric drills).
5. Do not mix with other types of batteries or modular units.
6. Do not excessively squeeze the battery during use.
7. Do not place the battery in a high temperature greater than 60°C.
8. Do not use conductive materials to connect the positive and negative terminals (such as metals, wires).
