    • Works Great
Size: 80 Amp
This NVX XSBI80 Microprocessor-Controlled 80 Amp Dual Sensing Smart Relay Battery Isolator works great and it charges the secondary battery while keeping the primary battery fully charged. I'm very happy with it and highly recommend this product. I installed it on my 2009 Yamaha Rhino 700 that I had added an auxiliary battery to that run my radio, wench, and other accessories on. I have read in other reviews that it overheats, but I have not found that to be the case in my installation. Perhaps some other folks did not install it properly. ... show more

    • Great for lead acid or AGM
Size: 80 Amp
This is a great isolator. I used it briefly on my UTV until changing to Lifepo4 batteries. My lead acid crank battery had a dead cell and drained my auxiliary AGM after a day or so. I can say the emergency button does work, follow the directions.....I wish there was a model that isolates at higher voltages for lithium type batteries ... show more

    • It really works, no more battery drain!!!
Size: 200 Amp
Very simple and easy to install, great value, and works as described. Had to separate my main and amp battery. Great investment!! The clicking sound is something to get use to, I'd be worried if I don't hear it click.

    • Works well
Size: 500 Amp
I would have given this product a 5 plus star review however I am disappointed with the emergency switch they provide to connect the two batteries together for jump start It’s extremely cheap and flimsy I really feel they should have spent an extra couple of dollars to make it much better I would have gladly spent an extra $20 for a better switch Other than that the product appears to work as it should I’ll give a better update as time goes on ... show more

    • Easy to install works great.
Size: 500 Amp
Very easy to install. One battery to one terminal second battery to the other and connect the ground. Works perfect on my 2 Advance Auto 900cca AGM (Identical to Optima, both made by Johnson Controls with different color plastic and half the price) batteries
