Attention of o eration
Charge
：
1. The battery pack must be charged with a special charger for lithium batteries. When charging the battery, please
make sure that the power supply voltage is consistent with the input voltage of the charger, and the output voltage
of the charger is consistent with the battery’s charging voltage. Unqualified chargers will lead to battery failure or
short life.
2. The charging position shall be well ventilated. Do not charge in high temperature environment, and keep away
from inflammable and explosive gases or objects. The charger and battery shall be well placed to prevent from
falling.
3. It is normal that the surface of the battery box is slightly heated during charging. If it is found that the surface
temperature of the battery box is too high, the power should be cut off immediately for further check.
. After full charge, unplug the charger in time, and then disconnect the charger and battery interface. This process
cannot be operated in reverse.
5. When the battery leaves the factory, the SOC is about 0% - 60%, which needs to be supplemented before use.
6. Do not directly connect positive and negative ports, which will hurt yourself or damage the battery.
7. The maximum charging time should be less than than 12 hours (the specific charging time depends on the use of
the battery. Do not charge for long time.

：
1. The battery can only be used for the intended purpose, not for other purposes.
2. The battery should be firmly installed in the vehicle/ vessel, so as to avoid the battery damage due to bumps
during the operation.
3. Do not use the battery in a wet environment
. Do not immerse the battery in water.
5. At normal temperature, the discharge performance of the battery is better, and at low temperature, the capacity
of the battery will decrease, so when the usage temperature is low, the working time of the battery after charging
will be reduced. This is normal.
6. The battery shall be placed in a place free from direct sunlight and radiation source, and the distance from the
heat source (fire source, heating, equipment, etc.) shall not be less than 2 meters.
7. Try to avoid using the battery in the place with strong static electricity. Static electricity can easily damage the
charging protection plate, resulting in abnormal operation of the battery.
