Abstract
A dual-contact battery pack comprises a housing, a plurality of battery cells located within the housing, a first set of contacts and a second set of contacts coupled to the housing and to the plurality of battery cells. The dual-contact battery further comprises a first control circuit coupled between the plurality of battery cells and the first set of contacts and a second control circuit coupled between the plurality of battery cells and the second set of contacts. The first and second sets of contacts enable the dual-contact battery pack to selectively switch from a first state which prevents current from flowing from the plurality of battery cells to the respective first and second set of contacts to a second state in which current flows from the plurality of battery cells to the respective first and second set of contacts in response to the respective first and second control circuits.
