Who It's For

This controller is aimed at DIY owners and small shops repairing 48V EZGO TXT, Terrain 250, ST Sport II, Express S4/L4, Shuttle 4X and compatible Cushman or Hauler carts from roughly 2010 to 2019 who need a practical replacement without custom setup. It is especially useful when the existing controller has a matching part number such as 1206HB-5201 or one of the listed equivalents.
