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.
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.
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.
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.

Must have with lifepo4 lithium cells
A must have if you are running a second battery, especially if you are running lithium cells or any secondary battery battery. It can save you the trouble of to dead batteries or overcharging lithium batteries.
Pros smart auto connect and disconnect of secondary battery from charging system which isolates it m from other battery. With it disconnected from main battery if somthing pull you voltage down it will not effect the secondary battery. Or trash lithium banks by pulling them down and not being able to charge them back up. Oh it also comes with a thin almost flat switch that you can manually connect both batteries together to jump start yourself.
Small Con for some, bit pricey compared to others but still a lot cheaper than replacing a bad battery.

Great
Love how it disconnects my back battery when car is off and since I have a high output alternator it almost instantly start charging my back battery along with my front battery so my voltage stays pretty steady on a salt 2 amp. I would definitely recommend this. And they're great customer service because the first one I ordered got lost by FedEx so they sent me a second one then the second one quit working after I upgraded my power cable from the primary battery to the secondary and they are exchanging it. So it's good all the way around.
