1. A battery pack comprising:
a pair of physically separate electrochemical batteries, each battery having a respective pair of electrodes projecting therefrom; and
a pair of protection circuits, each of which is electrically coupled to a corresponding one of the pair of batteries and is configured to control operation of the corresponding battery, the pair of protection circuits being provided by:
a single protective circuit board (PCB), the PCB having a pair of parallel major faces and a peripheral edge face extending transversely between the major faces, each major face carrying respective electronic circuitry comprising contact pads to which the pair of electrodes of a corresponding one of the pair of batteries is permanently connected, such that the electrodes of a first one of the pair of batteries are connected to contact pads on of a first one of the pair of major faces of the PCB, the electrodes of a second one of the pair of batteries being connected to the contact pads on a second, opposite one of the pair of major faces of the PCB; and
electronic protection circuit module (PCM) components mounted on the PCB such that the mounted PCM components of the pair of protection circuits are mutually exclusively located on opposite major faces of PCB, wherein:
the mounted PCM components forming part of a first one of the pair of protection circuits are mounted exclusively on the first major face and are conductively coupled to the respective pair of electrodes connected to the first major face of the PCB, and
the mounted PCM components forming part of a second one of the pair of protection circuits are mounted exclusively on the second major face and are conductively coupled to the respective pair of electrodes connected to the second major face of the PCB.
