It is designed to be safe and reliable, keeping your car running smoothly.Easy InstallationThis dual battery isolator kit includes all the accessories you need, which is easier to install and operate. You just need to connect the two batteries to the isolator and it will effectively transfer the charge from one battery to the other, much time saving.With Led VoltmeterThe 12v 140 amp dual battery isolator comes with Led Voltmeter Display, you can check your battery voltage directly at any time, more convenient and safe.If two batteries are connected, then the voltage displayed on the voltmeter is the battery that has higher voltage. Only connect the battery that you would like test the voltage and disconnect the other battery. When the voltmeter is not working, press the button once, the voltmeter will display the value for 2 seconds.Package IncludesWORKING PRINCIPLE:When the voltage of start battery is higher than cut-in volts, the smart battery isolator (SBI) keeps engaging, two batteries (start and house) are charged simultaneously. The unit Indictor (LED) is on. When the batteries no longer have a charge from the alternator, and loads on the batteries begin to drain them. Unit Indicator (LED) is on. When the voltage drops below cut-off volts for 5 seconds, the SBI senses it and disengages, separating both batteries. Unit Indicator (LED) is off. When the vehicle is restartd, the start battery has reached the cut-in volts, the SBI engaged again. The device Indicator (LED) is on.
