Abstract: A method for recalibrating an engine includes querying an engine for a unique engine identifier, sending the unique engine identifier to a cloud-based server, determining one or more engine calibration settings available to the engine based on the unique engine identifier sent to the cloud-based server, presenting the one or more engine calibration settings to a user through a user interface so that the user may select a desired engine calibration setting, sending the desired engine calibration setting as selected by the user to an electronic control unit of the engine, and replacing a current engine calibration with the desired engine calibration setting in the electronic control unit of the engine.

Abstract: A battery pack includes a housing, a positive terminal and a negative terminal, and a plurality of cell module assemblies. The positive terminal and negative terminal are each externally accessible from the housing and extend into a first compartment of the housing. The cell module assemblies are received in a second compartment of the housing, and are coupled to the positive terminal and the negative terminal through a connection extending from the second compartment into the first compartment. The first compartment is accessible through a first panel that is movably coupled to the housing through a first securing mechanism providing a first level of access. The second compartment is accessible through a second panel that is movably coupled to the housing through a second securing mechanism providing a second level of access.
