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.
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.
The charging process will charge both battery packs alter-
nately, automatically switching between both battery
packs numerous 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 with One Battery Pack Inserted
If only one battery pack is inserted, then you can charge on-
ly 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.

Always switch off the battery pack and the eBike sys-
tem when you insert the battery pack into the holder
or when you take it 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.
To insert the rack-type battery pack 2, slide it with the
contacts facing ahead until it engages in the holder 1 of the
rear rack/carrier.
Always check that the battery pack is locked in
place. To do this, pull on the battery pack handle (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.
Bosch eBike Systems
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.
To remove the rack-type battery pack 2, switch it off and
unlock the lock with the key 5. Pull the battery pack out of
the holder 1.
Operation
Initial Operation
Use only original Bosch battery packs approved for
your eBike by the manufacturer and purchased from
a trusted source. Use of non-approved or counterfeit
battery packs can lead to death or serious injury.
Switching On and Off
Switching the battery pack on is one of the ways of starting
the eBike system. Read and follow the operating instruc-
tions for the drive unit and the on-board computer.
Before switching on the battery pack or the eBike system,
2
check that the lock 6 is locked.
To switch on the battery pack, press the On/Off button 4.
The LEDs for indicator 3 light up and, at the same time, in-
dicate the charge condition.
Always check that the battery pack is locked in
place. To do this, pull on the battery pack handle (after
the key has been removed).
Note: When the battery pack capacity is below 5 %, none of
the LEDs for charge-control indicator 3 will light up. Only
the on-board computer will indicate if the eBike system is
switched on.
To switch off the battery pack, press the On/Off button 4
again. The LEDs for indicator 3 go out. This also switches
off the eBike system.
When no power output from the eBike drive unit is request-
ed for approx. 10 minutes (e. g., because the eBike is
parked) and no button for the drive on-board computer or
operating unit is pressed, then the eBike system, and thus
the battery pack, automatically switches off to save energy.

The battery pack is protected against deep discharging,
overcharging, overheating and short-circuiting by the
"Electronic Cell Protection (ECP)". In case of hazardous sit-
uations, a protective circuit automatically switches off the
battery pack.
When a defect in the battery pack is de-
tected, two LEDs for the charge-control
indicator 3 flash. In this case, please
contact an authorized Bosch eBike
dealer.
Transport
WARNING
Always remove the battery pack from the bicycle be-
fore transporting the bicycle on a vehicle bike rack.
Failure to remove the battery pack when using a vehicle
bike rack can lead to death or serious injury. The battery
may detach during transport and cause an accident to
following vehicles.
Always use an approved and compatible bicycle rack
when transporting your eBike. The Bosch Drive Sys-
tem adds weight to the bicycle. Refer to your bicycle
rack manual to be sure your eBike is compatible. Over-
loading a bike rack can result in death or serious injury.
Use proper lifting techniques because electric bikes
are generally heavier than bicycles.
Ship batteries only when the housings are undamaged.
Tape or mask off open contacts and pack up the battery in
such a way that it cannot move around in the packaging. No-
tify your parcel service that the package contains danger-
ous goods. Please also follow possibly more detailed na-
tional regulations. Always check the state and federal
regulations before attempting to ship your battery.
In case of questions concerning transport of the battery
packs, please contact an authorized Bosch eBike dealer.
Bosch eBike dealers can also provide suitable transport
packaging.
