storage.

• It is recommended to charge the battery
after use. Deep discharge is harmful to thebattery. Never fully discharge the battery.
If the battery remains uncharged for an
extended period, this will damage thecapacity of the battery. For storage, therecommended capacity of the battery should
be between (60-80%).

Do not disassemble the battery.
The battery contains protective components toavoid danger. Incorrect handling, such as
improper disassembly, can destroy the protectivefunctions and lead to overheating, smoke andexplosion.

• Do not charge the battery longer than thecharging time specified in the "SPECIFICATION" table.

This can cause errors or internal problems inside
the battery, also damaging the protectivefunction. It can lead to abnormal chemical
reactions or malfunctions that lead tooverheating, smoke and explosion.

The battery can be charged 600 times. The
battery capacity decreases during this time, thus
reducing the range of the pedelec. If battery's
capacity range is not enough, it may need to bereplaced.

8.1.1.4 Pedelec riding distanceDo not damage the battery.
The battery must not be dropped or damaged.
This can lead to overheating, smoke andexplosion. Never submerge the battery in water.

It is best to charge the battery at room
temperatures and insert the battery just before
the start of the journey. The discharge cycle ofthe battery can be affected by:• Used pedal power

Do not charge the battery directly fromthe socket or a cigarette lighter in the car.
High voltage and excessive current will damage
the battery and reduce its lifespan. It can lead tooverheating, smoke and explosion.

8.1.1.2 Battery Storage• Road/underground condition

If you do not use your pedelec for a long time,
remove the battery, and charge about (60-80%)
on. Store the battery separately in a suitable dry
place.
