Item Condition - Open Box, Good:
This product is used, but it will work like new and is in overall good condition. It will show signs of wear that can include scuffing, scratches, fingerprints, dents, and worn corners or installation marks. May be missing non-essential parts, accessories or original packaging.
The NXV BIR500 Isolator is the perfect solution when adding a secondary battery to your audio system. It allows the second battery to be fully dedicated to the sound system and does not create a voltage drop like common isolators tend to do. The isolator will draw less than 1 amp when your vehicle is powered on. All of this will ensure that your battery will be isolated with confidence!
When two vehicle batteries are wired in parallel they have a tendency to charge and drain one another. Installing a relay that disconnects the batteries when the engine is off prevents excessive wear and lengthens the life of the batteries. Whenever you turn your engine back on, the batteries will be connected without any voltage drop to the second battery.
