Description

technical field [0001] The invention to which this application relates is a portable power source, generally in the form of what is referred to as a battery pack, which can be detachably attached to a powered object, such as a power tool, in order to allow the power tool to be becomes operable while at least partially charging. Background technique [0002] It is known to provide battery packs that can be attached to power tools to allow power to operate the tool. Traditionally, for tools such as drills, reciprocating saws, etc., two types of specific modes will be provided, a first type connected to mains power and a second type in which power is supplied from a connected battery pack , so the second version allows the tool to be used in locations where it is not easy to connect to the mains. [0003] A battery pack generally includes a plurality of unit cells connected to each other to provide power therefrom. The unit cells are generally arranged in a sealed casing, an...
