Specially designed for farming, military, and international vehicles found outside the USA with multiple accessories. PriorityStart! is an automatic computerized on/off “switching” system protecting battery voltage and starting power. If battery voltage drains below 11.7 volts when engine is off, it automatically disconnects the load. The battery voltage immediately recovers. TO START: just step on brake pedal, starting power is automatically reconnected. Designed to handle 1600 “starting amps”.

Often multiple accessories mimic “engine run”. The PriorityStart! is specially designed to handle multiple accessory loads, utilizing higher value electrical components to monitor “engine run” when the engine is off.

PriorityStart! is successfully being used in vehicles with:

  • 2 way/CB radios
  • Radar Systems
  • GPS
  • Cell phones
  • Computers
  • Flashlight Chargers
  • Mobile Equipment
  • Dual batteries
  • Hi-Amp Stereo Systems
  • Mobile T.V

PriorityStart! is an electronic cut off switch. It will not charge or maintain a battery.

Always had trouble with batteries on our Dredge. This has helped with batteries not discharging during idle periods. So far so good.
