Isolate with Confidence

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 isloator 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!

Product Features:

  • Mobile Audio Relay and Battery Isolator
  • Great for isolating a second batter making it dedicated to the stereo system
  • Does not create a voltage drop to the second battery like conventional isolators
  • 500 Amps at 12V Continuous Power Handling
  • 700 Amps Surge Power Handling
  • Switching Power: 10 - 16 VDC
  • Draws Less Than 1 Amp When On
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Very happy.

July 13, 2014

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.

If you're a fan of NVX and need a high amperage isolator then this is the one to get. I'm currently running 0 gauge through it to my XS power battery and it does the job, no problems yet after using it for 6 months.

Solid product but not perfect

August 11, 2017

I would recommend the product but wish the packaging had included wiring instructions. Also, if you overtighten the nuts on the lugs it's easy to crack the plastic housing.
