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.

found this helpful.Very happy.
Product works just as advertised and suits my purposes perfectly. My second battery drives a heavy duty wench, fog lights, and stereo system and the NVX BIR500 has been keeping it well charged. It was easy and quick to install. The only thing I wish it came with would be rubber caps for the posts. I accidentally tapped them more than once, causing sparks (that's why the 3 under 'look/design'), Before I wrapped them in electrical tape. Other than that I've very happy with it.
