the operating instructions of the battery.
Charging with Two Battery Packs Inserted
If two battery packs are mounted on one eBike, both
battery packs can be charged using the unsealed con-
nection. To begin with, both batteries are charged
one after the other until they reach approx. 80−90 %
capacity, then they are both charged at the same time
until full (the LEDs on both batteries flash).
When the bike is in operation, power is drawn from
both batteries on an alternating basis.
If you take the battery packs out of the holders, you
can charge each battery pack individually.
Charging process
The charging process begins as soon as the charger is
connected to the battery or charging socket on the
bike and to the mains.
Note: The charging process is only possible when the
temperature of the eBike battery is within the permit-
ted charging temperature range.
Note: The drive unit is deactivated during the charg-
ing process.
The battery can be charged with or without the on-
board computer. When charging without the on-
board computer, the charging progress can be ob-
served via the battery charge indicator.
When the on-board computer is connected, a charg-
ing notification appears on the display.
The state of charge is displayed by the battery charge
indicator (9) on the battery and by the bars on the
on-board computer.
The LEDs on the battery charge indicator (9) will
flash during the charging process. Each solid illumi-
nated LED represents approximately 20 % of the
charging capacity. The flashing LED indicates the
next 20 % currently charging.
Once the eBike battery is fully charged, the LEDs ex-
tinguish immediately and the on-board computer is
switched off. The charging process is terminated. The
