Abstract: The present invention provides an enbloc clip-type lithium secondary battery pack capable of fitting into a four-cell (R6 standards cells) battery compartment of an electronic camera flash. The enbloc clip-type lithium secondary battery pack can increase an electric supply capacity (Wh) two times or more compared to a conventional low self-discharge nickel hydride batteries, thereby making it unnecessary to use a quick recycling battery pack or an external battery pack. Therefore, the enbloc clip-type lithium secondary battery pack can reduce the weight and cost of camera equipment.
