NOVELTY - Battery system (110) for an electric motor (104) of an electric motorcycle (100), comprises: (a) a motorcycle frame (102) defining an interior volume; (b) many battery cells situated substantially within the interior volume of the frame; (c) at least one housing member removably coupled with an exterior of the frame; and (d) at least one fastener for fastening the housing member to the frame.    USE - The battery system is useful for an electric motor of an electric motorcycle (claimed).    ADVANTAGE - The system utilizes the housing member that: allow a user, the ability to easily gain access to the individual battery cell without requiring any additional disassembly of the motorcycle, and when the individual battery cells becomes damaged or malfunction, the user can replace the sole damaged battery cell with a minimal amount of disassembly, thus increasing the usability of the electric motorcycle and simplifying the maintenance of the electric motorcycle, while reducing the maintenance costs; and allows greater volume of air to pass through the interior volume of the frame, and increases the heat dissipation and cooling capacity of the battery system, thus reducing heat damage to the battery cells, and increasing the life span.    DETAILED DESCRIPTION - Battery system (110) for an electric motor (104) of an electric motorcycle (100), comprises: (a) a motorcycle frame (102) defining an interior volume; (b) many battery cells situated substantially within the interior volume of the frame, where each battery cell is individually enclosed and individually electrically coupled with the electric motor of the electric motorcycle; (c) at least one housing member removably coupled with an exterior of the frame, where the housing member is perforated so as to allow airflow into the interior volume of the frame, and the removal of the housing member provides unfettered access to the battery cells so that each battery cell can be individually removed without requiring additional disassembly of the electric motorcycle; and (d) at least one fastener for fastening the housing member to the frame, where removal of the fastener results in decoupling of the housing member from the frame. An INDEPENDENT CLAIM is also included for a battery system, comprising (a) and (b) as above per se, (c1) a battery management system electrically coupled with the battery cells, where the battery management system monitors metadata of each battery cell, and (c) and (d) as above per se.    DESCRIPTION OF DRAWING(S) - The figure shows a side view of the electric motorcycle including the battery system.
