Battery life is a never ending challenge for drones of all types. The product you see here is the Blue Vigil RS1000, which operates with the DJI Inspire 1, Inspire 2, Mattrice 200/210 or any drone that operates on a 12 V or 24 V battery. Blue Vigil manufactures affordable tether power systems designed for off-the-shelf drones. The ground-based tether allows unlimited flight time when connected to a power source (generator, household current, or battery). The Blue Vigil system includes the ground base tether unit (RS1000), power cord and the Battery Replacement Module (BRM).
