3.2. Charging the battery
Li-ion battery of your e-bike can be recharged at any state of discharge. It is recommended
to fully recharge the battery after each ride, as soon as it has cooled to room temperature.
Use only the supplied charger. 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 GREEN- the battery is fully charged
Warning:
The battery is supplied partially charged. To ensure 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 instruc -
tions in the operating manual for the charger.
Battery protection
Li-ion battery in your e-bike is equipped with its own control unit - BMS (Battery Management
System). This system, inter alia, monitors and controls the charging and discharging currents and
also serves as protection against deep discharge or overcharging. However, if battery is auto -
matically switched off by BMS, do not attempt to restart the system and continue using motor
assistance. It may cause deep discharge of battery cells and its irreversible damage. This damage
can be diagnosed and is not covered by warranty. As soon as possible recharge the battery.
Warning:
Use only the charger, supplied with your e-bike and make sure not to confuse with another char -
ger. The battery charger can be used only indoor. Avoid any contact with water or other fluids
while charging the battery. If the battery, charger or any connections become wet, immediately
unplug the charger and thoroughly dry all components prior to charging the battery. Charging is
permitted only in temperature range 0 ~ 40 °C!
Storage
When storing your battery for a long period of time (longer than two months), remove the bat -
tery from the bike, recharge it and store in a cool, dry and safe place within the temperature
range of 0 ~ 25 °C . Lithium-ion batteries are best stored at a 40–60% charge level. During long
term storage, recharge your battery to 40–60% every 60 days. Determine charge level using
either the built-in charge indicator on the battery pack, or the battery gauge on the bike. Bat -
teries slowly self-discharge when left unused for a long period of time; if the battery cells are al -
lowed to reach a critically low voltage, their lifespan and capacity will be permanently reduced.
Range
Many factors affect the range that you will experience with the bicycle. These include:
- Selected degree of assistance - Battery state-of-charge
- Profile of the selected route - Weather conditions
- The total weight of the cyclist and baggage - Tire inflation pressure, etc.
For maximum range, fully recharge the battery and check the technical condition your E-bike
before each ride. With the correct gear choice and level of assistance so that you do not consu -
me unnecessary battery power, range on a single charge can be significantly increased.
