7 Battery

Your battery is a lithium-ion battery, the ideal type of
battery for this application.
One of the main benefits of this battery is its low weight
combined with a high capacity.
7.1

Straightforward charging

› Damaged batteries can neither be charged, nor
continue to be used.
› The battery may heat up during charging. A maxi-
mum temperature of 45°C may be reached. If the
battery becomes any warmer than this, suspend
the charging process immediately.
› During the charging process, the battery must be
positioned on an even, non-flammable surface.
The charger must not be covered.
• There is no memory effect. You can therefore fully
recharge your battery after every trip.
• Recharge the battery after every trip. This means
you can set off immediately the next time you use
your bike and you also increase the service life of
the battery.
• If you are not using the battery, you have to
recharge it after 6 months.

7.1.1 Learning cycle

Once you have fully charged the battery for the first
time, you must run it down until the system switches
off. Repeat this process roughly every six months. This
procedure (a so-called "learning cycle") is necessary
so that the battery management recognises the chang-
es in the capacity caused by age and wear and tear, in
other words, the performance level of the battery. This
is the only way to enable adjustments to your remain-
ing range indicator.
Afterwards, the capacity of the battery is calculated
anew and correctly represented.
With this procedure, you can prevent a sudden loss of
electrical assistance during an extended trip.
7.2 High degree of safety due to battery
management
• The battery cannot be damaged as a result of a
short-circuit. If this were to happen, the battery
management would switch off the battery.
• You can simply leave the battery connected to the
charger as it has in-built overcharging protection.
• The battery management monitors the temperature
of your battery and warns you of incorrect use.
