The Nocqua Smart Link Connector was specifically designed to accommodate anglers searching for additional power, without sacrificing added weight or storage space from a larger battery. Utilizing the proven technology from Nocqua, you can easily connect two Nocqua 4.4Ah batteries or two Nocqua 10Ah batteries for double the power. When your hands are full, let the smart switching technology seamlessly manage power to your electronic device. When battery one is drained, the Smart Link switches to the second battery. Keeping in line with our family of products, the Smart Link is compact, durable, functional, innovative and reliable when you need it most.
