  • Function: The Voltage Sensitive Relay (VSR) ensures that the primary battery is always charged and ready to start the vehicle by cutting in at 13.3 volts and cutting out at 12.8 volts. When your engine is turned on and the starting battery is fully charged, the isolation will start charging the second (auxiliary) battery at the same time. Enables you to charge two batteries from one alternator at the same time.
  • Safe and efficient: The dual battery isolator is made of high-quality material casing and a silicone seal, withstanding extreme weather conditions and vibrations. Its IP66 waterproof rating ensures safe off-road use in dusty, wet, and unpredictable environments, providing you with a reliable and durable solution for your marine or automotive dual battery needs.
  • Wide Application: Like Having Two Separate Power Sources, The Dual Battery Isolator Kit Enables Your Accessories to Run From a Separate Battery While the engine is not running on your vehicle While keeping your Main Battery Charged and Your Vehicle Always Ready to Go and Start When You Want It. Suitable for 12v camper van trucks, caravans, RV, ATV, UTV, Boat and camping applications.
  • Real-time voltage display: The Dual Battery Isolator 12V 140 AMP is equipped with an LED display that shows the current voltage status in real-time so that you can check the battery status at any time. Important Note: This item is not compatible with Lithium Batteries
  • Package Includes: 140amp smart battery isolator with voltage display; Mounting Hardware(screws, nuts, spring washers, ring terminal).
