To insert the rack-type battery pack 20, slide it with the
contacts facing ahead until it engages in the holder 19 of the
rear rack/carrier.
Check if the battery pack is tightly seated. Always lock the
battery pack with lock 24, as otherwise the lock can open and
the battery pack could fall out of the holder.
After locking, always remove the key 23 from the lock 24.
This prevents the key from falling out and the battery pack
from being removed from unauthorised persons when the
eBike is parked.
To remove the standard battery pack 26, switch it off and
unlock the lock with the key 23. Pivot the battery pack out of
the upper holder 25 and pull it by the carrying strap 28 out of
the bottom holder 27.
To remove the rack-type battery pack 20, switch it off and
unlock the lock with the key 23. Pull the battery pack out of
the holder 19.
Operation
Initial Operation
 Use only original Bosch battery packs approved for
your eBike by the manufacturer. Using other battery
packs can lead to injuries and pose a fire hazard. When us-
ing other battery packs, Bosch shall not assume any liabil-
ity and warranty.
Switching On and Off
Switching the battery pack on is one of the possibilities to
start the eBike system. Read and observe the operating in-
structions of the drive unit and the drive HMI.
Before switching on the battery pack or the eBike system,
check that the lock 24 is locked.
Note: When switching on the eBike system, the pedals of the
eBike may not be subject to load, as otherwise the output ca-
pacity of the drive will be limited.
To switch on the battery pack, press the On/Off button 22.
The LEDs of indicator 21 light up and at the same time indi-
cate the charge condition.
Note: When the battery-pack capacity is below 5 %, none of
the LEDs of charge-control indicator 21 will light up. Only the
drive HMI will indicate if the eBike system is switched on.
To switch off the battery pack, press the On/Off button 22
again. The LEDs of indicator 21 go out. This also switches off
the eBike system.
When no power output of the eBike drive is requested for ap-
prox. 10 minutes (e. g., because the eBike is parked) and no
button of the drive HMI or operating unit is pressed, the eBike
system and thus the battery pack automatically switch off to
save energy.
The battery pack is protected against deep discharging, over-
charging, overheating and short-circuiting through the "Elec-
tronic Cell Protection (ECP)". In case of hazardous situations,
Bosch eBike Systems
a protective circuit automatically switches off the battery
pack.
to an authorised bicycle dealer.
Notes for Optimum Handling of the Battery Pack
The battery-pack life can be prolonged when being properly
maintained and especially when being operated and stored at
the right temperatures.
With increasing age, however, the battery-pack capacity will
diminish, even when properly maintained.
A significantly reduced operating period after charging indi-
cates that the battery pack is worn out and must be replaced.
You can replace the battery pack yourself.
In case the carrying strap 28 of the standard battery pack
should be defective, please have it replaced by a bicycle deal-
er.
Recharging the Battery Pack prior to and during Storage
When not using the battery pack for a longer period, charge it
to approx. 60 % (3 to 4 LEDs lit on the charge-control indica-
tor 21).
Check the charge condition after 6 months. When only one
LED of the charge-control indicator 21 lights up, recharge the
battery pack again approx. 60 %.
Note: When the battery pack is stored discharged (empty) for
longer periods, it can become damaged despite the low self-
discharging and the battery-pack capacity may be strongly re-
duced.
It is not recommended to have the battery pack connected
permanently to the charger.
Storage Conditions
Store the battery pack in a dry, well-ventilated location. Pro-
tect the battery pack against moisture and water. Under unfa-
vourable weather conditions, it is recommended e. g. to re-
move the battery pack from the eBike and store it in an
enclosed location until being used again.
The battery pack can be stored at temperatures between
–10 °C and +60 °C. For a long battery-pack life, however,
storing the battery pack at a room temperature of approx.
20 °C is of advantage.
Take care that the maximal storage temperature is not ex-
ceeded. As an example, do not leave the battery pack in a ve-
hicle in summer and store it out of direct sunlight.
