5. Use precautions

5.1 It is forbidden to immerse the battery in seawater or water. When not in use, it should be placed in a cool and dry environment.

5.2 Exposure to sunlight, exposure to rain and snow is forbidden;

5.3 It is forbidden to use and leave the battery next to the hot and high temperature source, such as fire and heater;

5.4 Use a special charger for this type of battery pack when charging.

5.5 It is forbidden to use the battery to reverse the positive and negative electrodes;

5.6 Discard the battery to the fire or heater;

5.7 It is forbidden to use metal to directly connect the positive and negative electrodes of the battery to short circuit. It is forbidden to transport or store the battery together with metals such as hairpins and necklaces.

5.8 Disassembly is prohibited. Unauthorized removal of the battery pack may result in danger.


Storage and Transportation:
1.Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2.During transportation,50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.
3.Battery should be kept at -20℃~45℃ in warehouse where it's dry, clean and well-ventilated.
4.During loading of battery, attention must be paid against dropping, turning over and serious stacking.
