CAUTION
u
Do not connect the battery pack to the charger
until it has reached the allowable charging tem-
perature.
Battery charge indicator
The five green LEDs on the battery charge indicator
(3) indicate the battery's state of charge of when the
battery is switched on.
Each LED represents approximately 20% of the
charging capacity. When the battery is fully charged,
all five LEDs will be lit.
The battery's state of charge when switched on is also
shown on the display of the on-board computer. Read
and follow the instructions in the operating manuals
for the drive unit and on-board computer.
If the battery capacity is less than 5%, all the LEDs on
the battery charge indicator (3) on the battery will go
out. The display function of the on-board computer,
however, will carry on working.
Once charging is complete, disconnect the battery
from the charger and the charger from the mains.
Using two batteries for one eBike
(optional)
The manufacturer can also equip an eBike with two
batteries. In this case, one of the charging sockets will
not be accessible or it will have been sealed with a
sealing cap by the bicycle manufacturer. Only charge
the batteries via the charging socket that is accessi-
ble.
u
Never open charging sockets that have been
sealed by the manufacturer. Charging batteries
via a charging socket that used to be sealed may
cause irreparable damage.
If you want to use an eBike that is designed for two
batteries with only one battery, cover the contacts of
the unused socket using the cover (10) provided.
Otherwise there is a risk that the exposed contacts
will cause a short circuit (see figures A and B).
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 with one battery fitted
If only one battery is fitted, you can only charge the
battery that has the accessible charging socket on the
bike. You can only charge the battery with the sealed
charging socket if you take the battery out of the
holder.
