
If the device is not used for a long period, ensure the battery is fully charged before storing.
Charge the battery at least once a month.

There is a risk of a short circuit caused by foreign objects.


The battery and charger are for the WHILL Model C2/Ci2 only. Do not charge the battery by
using a charger other than the charger provided with the device or charge other batteries with
the charger provided with the device.
There is a risk of malfunctions.
• Install a charged battery and turn on the power after 5 seconds. If the unit does not start up properly, remove
the battery and reinsert it after at least 10 seconds.
• The charger is for indoor use only. Do not charge the battery outdoors.
• This product will decelerate if the battery temperature drops significantly in a low temperature (below 0°C)
environment. In that case, the driving speed on level ground will be limited to 3km/h at most. Although the
temperature of the battery is not the same as the air temperature or the ambient environment, do not leave
the battery in an environment below 0°C for a long time before driving.
• If you try to go up a steep slope when the battery temperature is low, the vehicle may stop.
• If you drive downhill with the battery near full charge, the car will decelerate. The lower the temperature of
the battery, the greater the deceleration.
• We recommend charging the battery regularly, each time you finish using it for example, so that the device has
a fully charged battery when it needs to be used. Although the device can be used without the battery charged
fully, in an emergency, the device may get stuck while driving if the battery charge level is low.
• If you have any questions about the battery, please contact your distributor or customer support.
