4.3 Transportation
The products shall be packed into boxes for transportation. During transportation,
violent vibration, impact or extrusion shall be prevented to prevent sunlight and rain.
Vehicles such as automobiles, trains and ships can be used for transportation.
Generally, lithium-ion battery products are not allowed to be transported by air. In
special circumstances, when it is needed to be transported by air, relevant certification
shall be carried out according to the requirements of UN38.3.
4.4 Storage
This product contains lithium-ion batteries. When storing, pay attention to the
power of the battery pack and the temperature and humidity of the whole storage
environment.
The battery pack is usually stored in a clean, dry, and ventilated room with an
ambient temperature of 25℃±5℃ and a relative humidity of not more than 75% at
45% ～55% charged state. Avoid contact with corrosive substances and keep away
from fire sources. And heat source.
From the date of delivery, it is recommended that the user should maintain the
lithium battery every 3 months according to the following methods:
At 25℃±5℃ temperature, charge (solar panel charge or car charge or adapter
charge) to full, then discharge (AC output is recommended to supply power to some
household appliances) to empty, and finally charge to 45%~55% SOC, so as to
prolong the cycle life of battery.
Note: when the machine is shut down due to low battery pack voltage, the user
must charge the battery within 30 days, otherwise the battery will be damaged.

5 Operating procedures and safety instructions
5.1 Precautions for use
1. When using this product, please control the use within the rated power range.
2. Use the original adapter to charge the product, do not replace the adapter
without permission.
5.2 Instructions
1、Please read the specification carefully before using the battery.
2、During use, keep away from heat source and high pressure, and do not make it
fall.
3、Do not short circuit the positive and negative poles of the battery, do not
disassemble the battery by yourself, and do not put the battery in the damp place, so
as to avoid danger.
4、When not in use for a long time, please store the battery in good condition and
keep the battery in a half-charged state. Please wrap the battery with non-conductive
material to avoid direct metal contact with the battery, causing damage to the battery.
Keep the battery in a cool and dry place.
5、Waste batteries should be handled safely and properly. Do not put them into
fire or water.
6、If the battery is used for other equipment, please consult with the supplier, and
do not use the battery pack for other systems without authorization.
5.3 Danger Warning
1、It is forbidden to disassemble the battery inside the product
The protection mechanism and protection circuit inside the battery can avoid
danger. Improper disassembly and assembly will damage the protection function and
cause the battery to heat, smoke, deform or burn.
2、Do not short circuit the battery inside the product
3、Do not connect the positive and negative electrodes of the battery with metal,
do not store and move the battery pack together with the metal sheet. If the battery is
short circuited, there will be a large current flow, which will damage the fuse.
4、It is strictly forbidden to heat and burn the battery inside the product
Heating and burning the battery will cause the dissolution of the battery insulator,
loss of safety function or electrolyte burning. Overheating will cause the battery to
heat, smoke, deform or burn.

17
5.、Avoid using batteries near heat sources
Do not use the battery near the fire source, oven or in the environment over 80℃.
Overheating will lead to internal short circuit of the battery, causing the battery to heat,
smoke, deform or burn.
6、Do not soak the product to wet the internal battery
Do not wet the battery, and do not put the battery into water. Otherwise, the
internal protection circuit and function of the battery will be lost and abnormal
chemical reaction will occur. The battery may be heated, smoking, deformed or
burned.
7、No live dismantling
When the product is working, there is high voltage inside. It must be shut down
before dismantling to ensure that all output interfaces have no voltage.
8、Do not damage the battery
It is forbidden to chisel the battery with metal, hammer or drop the battery or
damage the battery by other means, otherwise it will cause the battery to heat, smoke,
deform or burn, and even cause danger.
9、Direct welding on the battery body inside the product is prohibited
Overheating will cause the dissolution of the battery insulator and the loss of safety
protection function, which will make the battery heat, smoke, deform or burn.
10、Do not touch the leaking battery directly
Leakage of electrolyte will cause skin discomfort. In case of electrolyte entering
eyes, rinse with water as soon as possible and send to hospital for treatment.
5.4 Types of Hazards
The customer should be aware of the following potential hazards during battery
use and operation:
1、Operators may be injured by chemicals, electric shocks or electric arcs during
operation. Although the human body responds differently to direct current and
alternating current, DC voltage and alternating current higher than 50V are more
serious to the human body. Therefore, customers must take a conservative posture
during operation to avoid current damage.
2、There is a chemical risk from the electrolyte in the battery.
3、When operating the battery and selecting personal protective equipment, the
customer and its employees must take into account the above potential risks to

18
prevent accidental short circuit and cause arc, explosion or heat out of control.
4、When the product works, there is high pressure inside. The user must take
conservative actions in operation to avoid high pressure injury.
