This 70 Amp Dynamic controller for Golden Companion I (GC221) and Companion II (GC321, GC421) mobility scooters is specially programmed for those models. You may select your controller with or without the optional wire harness.
Made by Dynamic, one of the top names in the mobility electronics industry, this is known by the manufacturer as the Rhino.
Please note that this controller is for first-generation Companion scooters such as the GC221, GC321, and GC421. If you have a later, second-generation Companion like the GC240, GC340, or GC440, then you will need the
90 Amp Dynamic R-Series Controller for the Golden Technologies Companion (GC240, GC340, GC440) and LiteRider (GL110, GL140) Scooters. The two controllers are not interchangeable.
