CelLink&rsquo;s high-conductance circuits integrate busing, fusing, voltage monitoring, and temperature monitoring wiring systems into a single circuit. Our circuits provide much greater control over power and data transmission than traditional round wire &ndash; at 1/4th the weight and 1/10th the volume. Thanks to a completely tool-less manufacturing process, CelLink&rsquo;s minimum order quantity is one.
