When charging the eBike battery on the bike, the battery of
the on-board computer can also be charged.
During the charging procedure, the LEDs of charge-control
indicator A3 on the battery pack light up. Each continuously
lit LED is equivalent to a charge capacity of approx. 20 %. The
flashing LED indicates the charging of the next 20 %.
 Be careful when touching the charger during charging.
Wear protective gloves. The charger and the combina-
tion plug can heat up severely, especially if the ambient
temperature is high.
Once the eBike battery is fully charged, the LEDs extinguish
immediately and the on-board computer is switched off. The
charging procedure is terminated. The charging state can be
displayed for 3 seconds by pressing the on/off button A4 on
the eBike battery.
After charging, always disconnect the charger from the on-
board network and the battery from the charger.
Note: When the eBike battery is not connected to the Travel
Charger, the discharge protection function is not active and
energy will continue to be drawn from your vehicle battery
which can become completely discharged after a while.
When disconnecting the battery pack from the charger, the
battery pack is automatically switched off.
Note: If you have charged on the bike, carefully close the
charge socket C6 with the cover C7 after the charging proce-
dure so that no dirt or water can get in.
If the charger is not disconnected from the battery after
charging, after a few hours the charger will switch itself back
on, check the charging state of the battery and begin the
charging procedure again if necessary.
