Battery is automatically locked after assembly into the frame. The battery lock is used as a pro-
tection against theft and also as a protection against spontaneous battery drop out during a ride.
Take out the key from the lock and keep it in a safe place for the following battery disassembly.

3.2. Charging the battery

The Li-ion battery of your E-bike can be recharged at any level of discharge. It is recommended to
recharge the battery fully after each ride, as soon as it cools down to a room temperature. Do not
use the charger with a damaged case or power cord. There is a risk of electric shock.
Meaning of the LED charger status indicator:
RED – the battery is charging
Warning:
The battery is supplied as partially charged. To ensure the full battery capacity, fully charge
the battery in the charger before using it for the first time. To charge the battery, read and
follow the instructions in the operating manual for the charger.
Battery protection
The Li-ion battery in your E-bike is equipped with its own control unit - BMS (Battery Management
System). This system monitors and controls charging and discharging and also serves as a protec-
tion against deep discharge or overcharging. However, if the battery is automatically switched off
by BMS, do not attempt to restart the system and do not continue using engine assistance. It may
cause deep discharge of the battery cells and its irreversible damage. This damage can be diag-
nosed but is not covered by warranty service. Recharge the battery as soon as possible.
Warning:
Use only the charger supplied with your E-bike. The battery charger can be used only indoors.
Avoid any contact with water or other fluids while charging the battery. If the battery charger
or any connectors become wet, immediately unplug the charger and dry all components before
battery charging. Charging is permitted only in the temperature range 0 ~ 40 °C!
Storage
With daily use, it is not necessary to remove the battery from the frame. If the bike will not
be used for a long time, always remove the battery, store it in a dry and safe place in the tem-
perature range 5 - 25 ° C. Recommended environment for storing batteries is a dry place with
a constant temperature of between 15 - 20 ° C. (Temperatures below freezing point, but also
too high temperatures are not suitable for storing the batteries. Storage temperatures above
40 ° C are too high for long-term storage!) Be careful not to short-circuit the battery contacts
when storing or handling batteries. During the long-term storage, such as off-season, charge the
battery to its full capacity and recharge the battery to this level at least once in every 4 months.
Disconnect the battery from the charger when fully charged. Do not leave the fully charged bat-
tery connected to the charger.
