it works as it should!

its a must have if you are running two batteries. i had mine installed by a certified installer and no more juice sucking from my starting battery. i have a hifonics brx 14001.d and two 15 inch kicker cvr (2010 model) with the kinetik hc600 battery and all is well,so get it and be done with worries about your car not being able to start!

Nvx isolator

works good bought with a xs power battery install kit and works good and easy to install

nice power

this relay is what I need to run my stereo without loosing power it allows 2 battery's to run n charge specially now that s hot ac draws lots of current

good deal

Fast shipping. Product came in a well packed box.

Great Value

I use this relay to connect the chassis and coach batteries on my motorhome for charging and possible emergency start if a battery runs down.The old one with a different brand name failed in less than 2 years.I now have it wired to a toggle switch as it is not needed often since adding solar panels to my rv. The NVX BIR200 appears to be well built and functions perfectly. It energizes properly and shows no voltage drop across its contacts. Does what I need.

Slightly overpriced

Works as it should. Wish the design was a bit better, in order to attach terminals easier, but that's the only thing available for the money. Otherwise, one would either have to take out a mortgage, sell a kidney or design their own.
This product did not exceed my expectations, thus, a three-star rating.

Awesome deal!!! You know what you get with this one!

Good for systems that need a lot of extra bass power!

Good Quality

Nice weight to it and does what’s advertised. Nothing to complain about

Works!, no issues.

Using to isolate a small battery that helps power my 1700watt amp.

Just what I needed to solve 2problems

I would recommend this to anyone putting in an aftermarket system using the factory radio.

Yeee

so far NVX has rocked it on price, looks, and performance.

Great product, great price

Working perfectly. Isolates my system battery from my starting battery. I’m still running my stock 130amp alternator so this 200amp isolator did the trick
