Speedrite 18000i Fence Charger

The Speedrite 18000i is one of the world's most powerful battery powered fence charger.  Powering up to 270 acres of fencing wire, and with a maximum output energy of 18-joules, this charger gets the job done.


  • Designed with a Low Energy Terminal that limits energy to below 1.5 J for use around buildings and houses.
  • Cyclic Wave™ technology provides a cleaner, more powerful pulse, maximizing the energy that travels down the fence for optimal stock control.
  • Works with the ST102 remote - enabling you to switch the fence charger on and off from any location on the fence.  Particularly useful for repairs and maintenance.
  • Day/Night sensor. Automatically adjusts pulse speed to contain or exclude animals based on day or night conditions
  • Back-lit LCD voltage display shows output voltage, battery voltage and earth voltage.
  • Easy to read light bar display shows the output voltage and battery condition for quick fence diagnostics.
  • Microprocessor technology automatically adjusts the output energy depending on the battery charge. This feature extends battery life and is especially useful when used with solar panels.
