•• Do not extend the battery to temperatures
below the permissible storage temperatureof -10 °C to 35 °C. Note that temperaturesof about 45 °C are common near heaters,in direct sunlight or in overheated vehicle
interiors.
Do not continue to use the battery if you noticethat it gets hot during operation, charging orstorage, develops a strong smell, changes itsappearance, or is otherwise unusual. Do notcontinue to use the battery and have it checked

Do not charge the battery near open fireor in direct sunlight.
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 500 times. Thebattery capacity decreases during this time, thus
reducing the range of the pedelec. If the range
is not enough depending on the capacity of thebattery may need to be replaced.

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.

•• Total weight (load and driver)•• Tire air pressure•• Headwind•• Ambient temperature

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 dryplace.

•• selected speed level•• Slope•• Battery charge level•• Avoid direct sunlight from the sun, as it may
cause it to overhead, and cause internal
problems in the battery. It can lead to abnormal chemical reactions or malfunctions thatlead to overheating, smoke and explosion.
