160A Voltage Sensitive Relay


The ePOWER VSR or Voltage Sensitive Relay is essential for systems that are connected to more than one battery. Available in 140amp (Start Assist), 140amp and 160amp models.

When the engine is started, starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.2 volts the VSR engages allowing both starting and auxiliary batteries to be charged. When the engine is stopped and the battery voltage falls below 12.8 volts the VSR disengages separating the start and auxiliary batteries. The auxiliary battery continues to power any accessories without risk of draining the starting battery.

Additionally, the ePOWER VSR range offers features like :

  • No voltage loss
  • Intelligent battery monitoring to prevent unwanted switching
  • Starter battery priority
  • Bipolar switching
  • Voltage dependent switching


  • Marine
  • Caravans
  • Camper vans
  • RV’s
