There is provided battery cell assembly for a power tool battery pack. The battery cell assembly comprises a cell housing, a battery cell and a cell strap. The battery cell define a pole and is supported by the cell housing. The cell strap comprises a leg for electrically contacting the pole. The cell housing defines a first formation and the cell strap defines a second formation configured to engage the first formation so as to align the leg with the pole.

Battery pack and method

A battery pack comprising a frame and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a rotatable connector which is configured to enable electrical connections between the two or more battery cells. The rotatable connector is adapted to be switched between at least a first rotational position in which the two or more battery cells being electrically connected, and a second rotational position, in which the two or more battery cells being not electrically connected. When the user actuates the knob on the battery pack, the connecting terminals change their rotational positions from a non-conducting position to a conducting position, thereby enabling the electrical connections between the groups of battery cells.
