Charge-control Indicator
When the battery pack is switched on, the five green LEDs
for the charge-control indicator 3 indicate the charge con-
dition of the battery pack.
Here, each LED indicates approx. 20 % capacity. When the
battery pack is completely charged, all five LEDs light up.
The charge-control for the switched on battery pack is also
indicated on the display for the on-board computer. Read
and follow the operating instructions for the drive unit and
the on-board computer.
When the capacity of the battery pack is below 5 %, all LEDs
for the charge-control indicator 3 on the battery pack turn
off; however, the on-board computer does provide an addi-
tional indicator function.
After charging, disconnect the battery from the charger and
the charger from the network.
Using Two Battery Packs for One eBike (optional)
An eBike can also be equipped with two battery packs by
the manufacturer. In this case, one of the charge sockets is
not accessible or is sealed by the eBike manufacturer with
a sealing cap. Charge the battery packs only at the accessi-
ble charge socket.
 Never open charge sockets that have been sealed by
the manufacturer. Charging at a previously sealed
charge socket can lead to irreparable damage.
If you have an eBike that is designed for two battery packs
and you want to use it with only one battery pack, cover off
the contacts of the unused socket using the cover lid 10
provided because otherwise the open contacts pose a risk
of short-circuiting.
Charging with Two Battery Packs Inserted
If two battery packs are mounted on one eBike, both bat-
tery packs can be charged using the unsealed connection.
First, the two batteries are charged one after the other up
to 80 –90 %, and then they are fully charged in parallel
(The LED of each battery will flash).
Both battery packs are discharged alternately during oper-
ation.
If you take the battery packs out of the holders, you can
charge each battery pack individually.
Charging with One Battery Pack Inserted
If only one battery pack is inserted, then you can charge
only the battery pack that has the accessible charge socket
on the bike. You can charge the battery pack with the
sealed charge socket only when you take the battery pack
out of the holder.

In order for the battery pack to be inserted, the key 5 must
be inserted into the lock 6 and the lock must be unlocked.
To insert the standard battery pack 8, place it with the
contacts on the lower holder 9 on the eBike (the battery
pack can be inclined up to 7° to the frame). Tilt it into the
upper holder 7 until it engages.
 Always check that the battery pack is locked in
place. To do this, pull on the battery pack (after the key
has been removed).
Check if the battery pack is tightly seated. Always lock the
battery pack with lock 6; otherwise the lock can open and
the battery pack could fall out of the holder.
After locking, always remove the key 5 from the lock 6. This
prevents the key from falling out and the battery pack from
being removed by unauthorized persons when the eBike is
parked.
To remove the standard battery pack 8, switch it off and
unlock the lock with the key 5. Tilt the battery pack out of
the upper holder 7 and pull it out of the lower holder 9.
