1. An outdoor power equipment system, comprising
a removable rechargeable battery module;
a robotic lawn mower, comprising:
a receptacle configured to receive the battery module;
an electric wheel motor electrically coupled to the receptacle to receive electricity to drive a wheel;
an electric blade motor electrically coupled to the receptacle to receive electricity to rotate a cutting implement;
a gyroscopic sensor configured to detect an orientation of the robotic lawn mower;
a location sensor configured to determine a location of the robotic lawn mower; and
a controller configured to provide additional power from the battery module to the electric wheel motor based on at least one of (a) detection of a deviation by the robotic lawn mower from a desired path to maintain the robotic lawn mower on the desired path based on the location of the robotic lawn mower as determined by the location sensor, and (b) detection of the orientation exceeding a predetermined threshold value; and
a portable power equipment, comprising:
a receptacle configured to receive the battery module; and
at least one of an electric motor, a light source, and an amplification circuit coupled to the receptacle to receive electricity.
