Charging with Two Battery Packs Inserted
If two battery packs are mounted on one eBike, both battery
packs can be charged using the unsealed connection. The
charging process will charge both battery packs alternately,
automatically switching between both battery packs numer-
ous times. The charging times add up.
Both battery packs are also discharged alternately during
operation.
If you take the battery packs out of the holders, you can
charge each battery pack individually.
Charging Procedure
The charging procedure begins as soon as the charger is
connected to the battery or the charge socket on the bike and
the main power supply.
Note: Charging is only possible if the temperature of the
eBike battery is within the permitted charging temperature
range.
Note: The drive unit is deactivated during the charging proce-
dure.
The battery can be charged with and without the on-board
computer. When charging without the on-board computer,
the charging procedure can be observed on the battery
charge-control indicator.
When the on-board computer is connected, a corresponding
message is shown on the display.
The charging state is displayed by the battery charge-control
indicator 9 on the battery and by the bars on the on-board
computer.
During the charging procedure, the LEDs of charge-control
indicator 9 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 %.
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 10 on
the eBike battery.
Disconnect the charger from the main power supply and the
battery pack from the charger.
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 6 with the cover 7 after the charging procedure
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.
