Eliminate Voltage Drop

These Smart Battery Isolators are designed specifically for use in multi-battery applications. The XSBi series of isolators primarily monitors 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. This ensures you should never have a drained starter battery again.

Lengthen the Life of Your Batteries

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. This prevents excessive wear and lengthens 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.

Upgrade Nearly Any Ride

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. High power output amplifiers require a lot of power from your charging system. Upgrading it with a second battery will be a necessary addition to your car. For UTVs and ATVs, their batteries are too small to power any additional accessories like stereos and speakers. Therefore, if you want to add those additional accessories you will need an additional battery as well. In both of these applications, this smart isolator would be perfect to monitor your batteries’ voltage.

Manual Override Switch Included

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. This is 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.

Frequently Asked Questions (FAQ)


No ignition wire needed! The XSBI80 has a built-in microprocessor that "watches" your battery voltage. It automatically connects the batteries when it senses charging (13.2V) and disconnects them when the engine is off (12.7V).
It triggers based on voltage, not a key turn. Once your alternator starts charging and the main battery hits 13.2V, the unit clicks on. This simplifies install by eliminating the need to find a 12V switched source in your dash.
That is for the included Manual Override Switch. If your main battery dies, you can press this button to "link" both batteries for 60 seconds, allowing you to jump-start yourself using the power from your auxiliary battery.
The XSBI80 uses flash codes for diagnostics. 2 flashes means Over-Voltage (>15.5V), and 3 flashes means the voltage has dropped below 12.7V. Check your alternator or battery health if you see the 2-flash warning.
No. Old-style "diode" isolators drop about 0.7V, meaning your second battery never fully charges. The XSBI80 uses a high-current mechanical solenoid to create a direct connection, ensuring both batteries see the exact same charging voltage.

Easy setup

Works great and was easy to install! Haven't had it for very long but will assess durability once I've had it for awhile.

Easy install, Worry-free battery isolation

I recommend battery isolators to every customer who has an auxiliary battery system installed, and have been using the NVX ones since opening the doors of my business two years ago. Love the quality, and now the smart isolators have made the process even easier, with no need to run a separate auxiliary wire anymore. Simply connect to primary battery, auxiliary battery, and ground. ¡Voila! Easy peasy
