1.【Smart Battery Isolator】Battery isolator are combined auto&manual modes.Allows you switch between any modes to meet your needs.Convenient to use.the voltage display range:4.5V-20V.
2.【Voltage Setting Function】12V 140Amp dual battery isolator with voltmeter design which will display the real-time
voltage,meanwhile,allows you to freely setting the Cut-In/Cut-Out voltage for different types of batteries.the main battery
adjustable voltage range is 11.0V-14.0V.
 3.【Delay Setting Function】Feature delay function prevent battery drain out and prolonging the isolator and battery
 lifespan.Delay time range:3s-60s, setting with a recommended delay time of 15s.
 4.【Voltage Sensitive Relay】Voltage Sensitive Relay (VSR) cuts in at 13.3 volts and cuts out at 12.8 volts to ensure your
primary battery is always charged and ready to start your vehicle,don’t worry about the battery will drain out and stuck on the road.
 5.【High & Low Pressure Protection】Input voltage lower than 11V or Input voltage more than 17V:Circuit will be automatically disconnected so as to protect the main battery from over discharging.
