Battery pack

A battery pack, comprising:

• a housing;
• a frame disposed inside the housing;
• and
• two or more cells mounted to the frame, the two or more cells connected with each other through a configurable connector, and the configurable connector being suitable to connect or disconnect an electrical connection between the two or more cells, wherein the configurable connector comprises two terminals and an intermediate conductor simultaneously contacted with or separate from the two terminals;
• wherein the configurable connector comprises a user contactable switch located on an outer surface of the housing;
• the user contactable switch configured to move within a plane parallel to the outer surface, such that the configurable connector is switched between a first state and a second state;
• in the first state, the electrical connection existing between the two or more cells;
• in the second state, the electrical connection not existing between the two or more cells;
• wherein the intermediate conductor is fixed to the user contactable switch;
• the terminals respectively connected to one of the two or more cells;
• when the intermediate conductor is not contacted with the terminals, the electrical connection not existing between the terminals, such that the configurable connector is at the second state;
• when the intermediate conductor is contacted with the terminals, the terminals being connected with each other through the intermediate conductor, such that the configurable connector is at the first state, and wherein switching between the first state and the second state elastically deforms a portion of the configurable connector.
