Isolate with Confidence

The NXV BIR80 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
  • 80 Amps at 12V Continuous Power Handling
  • 150 Amps Surge Power Handling
  • Switching Power: 10 - 16 VDC
  • Draws Less Than 1 Amp When On
  • Dimensions: 2-7/8"W x 1-3/8"D x 3"H
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Excellent product but carrier for delivery should be changed

September 17, 2013

Excellent and performing as expected. However, usage of USPS instead of UPS to ship from US to Canada would save a lot to the Customer. Beside Canadian taxes and Customs fee, UPS charged to me as much as what it cost me for the product is not acceptable.

Survives!!

March 5, 2014

I've had this under my hood during the winter (temps of -20 without windchill) and it keeps working. Easy to use, and small enough to find into a tight engine bay. Just make sure you don't over draw it.

Great product!

July 25, 2013

I got it from Sonic three weeks ago and had it installed in my car by pros. I'm using it to isolate one Shuriken BT-20 that is powering my music. I started using it with one amplifier configuration. Now I have two amplifiers. I'm listening to music for about 2 hours with the engine off at loud volume and I haven't had a battery discharged yet. I don't recommend using the system with the engine off for extended periods but for the purpose of running a test it'll be fine. The isolator is working. It's pretty small, so it fits almost anywhere. For this application, with one secondary battery powering two amplifiers, it gets the job done. And that's enough for me. If your building a system like mine, then you got to purchase this isolator.

Does what it is supposed to

August 10, 2015

This item works great to protect your starting battery while playing music with the engine off. I even purposely tested to make sure only the battery hooked to the amps drained down after an extended time of use. No complaints on any NVX product.

Needed very badly

April 19, 2017

What a great product, NVX has great products. I have one amp on a toggle switch because the remote switch in the amp is stuck in the on position and sometimes I forget to turn the amp off went I park my car over night and my batteries go dead. I installed this product now my problem is over, I never have to jump start my car again and it was so easy to install. Thank You Sonic Electronic and thank you NVX for making such great products

To take the strain off of my battery
Damien L on Dec 2, 2016
Replaced a diode isolator in a 2000 Roadtrek 190, (Dodge Ram Van 3500) to eliminate the annoying 0.7 volt drop in terminal charge voltage.
David D on Jun 10, 2016
Would this isolator pair well with the XS Power XP750-CK? I have a 160 amp alternator and will be running a Rockford Fosgate T-1500 BD at 2 ohm and an NVX JAD800.4.

Best Answer: It would for a second battery. But it's only rated 150 amp surge so if for some reason your switching this relay under a booming bass loaded soundsystem there may be some heat issues. It's 12volts only to close the contacts then it's sorta like an 100 amp fuse, if that helps.
