Very Important! About delivery and transportation Time&Please note: we do not accept the dispute of no update logistics!

1,Because the battery (especially the high-power battery you purchased) is a special commodity, the terms of transportation are very strict, all logistics companies in China, including China Post, UPS, FedEx, DHL, are unable to directly transport electricity Pool.
2,So we will start to transport your order from Hong Kong. Once the battery arrives in Europe or US, we will declare for import at the European or US customs. When the battery passes through the European or US customs, we will send it to you by UPS or FedEx. so the UPS number we provide will not be updated before the battery passes the customs. This is normal. 
3,It will takes 35-45 working days for delivery .Generally, after 35-45 working days, the package will arrive at the transfer station. After the customs clearance is completed, the package will be picked up and delivered, and the logistics information will be updated.
3,Once UPS's transportation number is updated, you can receive the goods within 3-5 days at most.

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.

Prohibited matters
Do not charge beyond the maximum charging rate.
Do not disassemble or modify the battery.
Do not throw or hit the battery.
Do not pierce the battery with sharp objects (such as nails, knives, pens, electric drills).
Do not mix with other types of batteries or modular units.
Do not excessively squeeze the battery during use.
Do not place the battery in a high temperature greater than 60°C.
Do not use conductive materials to connect the positive and negative terminals (such as metals, wires).
