A housing of a conformal wearable battery (CWB) encloses a plurality of battery cells arranged in a grid-like pattern and electrically connected to a printed circuit board (PCB). The PCB includes an electrical connection pad that is electrically coupled to a positive terminal of a battery cell of the plurality of battery cells and a positive conductive region receiving electrical energy from one or more of the plurality of battery cells. A redundant trace fuse circuit is formed on the PCB to facilitate electrical connection of the electrical connection pad and the positive conductive region. The redundant trace fuse circuit includes a first fusible link for electrically connecting the first electrical connection pad to the positive conductive region and a second fusible link that is selectively enabled to electrically connect the first electrical connection pad to the positive conductive region when the first fusible link is inoperative.
