Title: BATTERY PACK WITH MULTIPLE OUTPUT MODES
Abstract:
A battery pack configured to be detachably installed in an electrical device. The battery pack contains a housing; N sets of electrically connected battery cells housed within the housing; N pairs of switching terminals; and a voltage control module. N is an integer. Two switching terminals in each one of the N pairs electrically connect to a positive output and a negative output respectively of one of the N sets of electrically connected battery cells. The voltage control module is electrically connected between the switching terminals and a plurality of output terminals configured on the housing. The voltage control module is arranged to connect the N switching terminal pairs in series or in parallel in order to output an electrical power from the battery pack to the electrical device. The battery pack is able to perform an internal switch-over of series and parallel connections between the sets of battery cells, therefore providing a great flexibility to the battery output.
