Claim 18:
19. A battery pack assembly comprising:
battery cells, each comprising a battery terminal; and
an interconnect circuit comprising a conductive layer and an insulating layer, wherein:
the insulating layer is laminated to at least a portion of the conductive layer and is positioned between at least portions of the conductive layer and the battery cells,
the conductive layer comprises conductive layer islands, each comprising a contact pad, a fusible link, and a remaining portion,
the insulating layer mechanically supports and maintains registration of the conductive layer islands relative to each other,
the contact pad is partially surrounded and separated from the remaining portion by a conductive layer channel,

the contact pad is connected to the battery terminal of at least of the battery cells,
the fusible link forms an electrical connection between the contact pad and the remaining portion,
the fusible link is configured to control a current flowing between the contact pad and the remaining portion and to break when the current exceeds a set threshold, and
at least a portion of the fusible link is freestanding and is not attached to the insulating layer,
the insulating layer comprises an insulating layer opening aligned and overlapping with the contact pad such that the contact pad is freestanding and is not attached to the insulating layer, and
the fusible link overlaps with the insulating layer opening.
