These Smart Battery Isolators are designed specifically for use in multi-battery applications, primarily monitoring the main starter battery voltage. Once the starter battery voltage reaches 13.2 volts, the solenoid automatically connects the auxiliary battery to the charging system. When the whole system drops below 12.7 volts, the solenoid opens and isolates the starter battery from the auxiliary battery, ensuring you never have a drained starter battery.

These smart battery Isolators also help lengthen the life of your starter battery. When two-vehicle batteries are wired in parallel, they have a tendency to charge and drain one another. All relays disconnect the batteries when the engine is turned off, preventing excessive wear and lengthening the life of the batteries. When you turn your engine back on, the batteries will be connected without any voltage drop to the second battery.

This smart isolator is a must when adding a second battery to your vehicle. In your car, you might be looking to add a second battery when installing a competition-grade amplifier, as high power output amplifiers require a lot of power from your charging system. For UTVs and ATVs, their batteries are too small to power any additional accessories like stereos and speakers, so an additional battery will be necessary.

The NVX XSBi Series includes a manual override function that allows you to disconnect or link the two batteries with the push of a button, necessary for emergency situations like jump-starting your vehicle. In this case, you would want to use the override function to manually disconnect the batteries from one another so you could just power the main battery to start your vehicle.

With 200 Amps of continuous power handling and 300 Amps of surge power handling, this microprocessor-controlled smart relay battery isolator is great for isolating a second battery, making it dedicated to the stereo system without creating a voltage drop to the second battery like conventional isolators. Featuring a switching power range of 10-16 VDC and drawing less than 1 Amp when on, this compact unit measures 2-3/8"W x 2-3/8"D x 3-3/4"H.
