Battery
The Khepera III is equipped with a battery pack composed of two Li-Ion
Polymer element. This provides a 7.4V volt battery with a 1400 mAH
capacity. Using its embedded power, the robot is able to run completely
autonomously during more than four hours, running with a basic configu-
ration. When additional equipment are used, the autonomy is reduced as
Khepera’s extensions as the KoreBotLE rely on Khepera’s batteries as a
power source.
There is no specific power management system on the Khepera. When
the batteries voltage falls under 6V, the battery cut himself the power supply
to avoid a too important discharge of the cell. Users can implement their
own software power management system to handle KoreBotLE to shutdown
properly before this case happend. See command ’V’ in chapter A for more
details about battery management.

Power Supply
If an external power source is required or during batteries charge, power
can be supplied through the power jack connector or through the micro-
Match cable unroller connector. See section 4 for detailed description of
connections.
Use only the power supply deliver by K-Team. If you want to
supply the Khepera III with another device, make sure that the
Voltage is +9V and that the power supply can deliver 2A.
SAFETY PRECAUTION: The power supply must be con-
nected to the wall socket after all other connections are already
made.
