These things work great I looked at the nvx and stinger models, they are the same, identical, just a lot cheaper. I use 2 of these in a 10,000 watt car stereo to separate my AGM starter battery from my trunk lithium battery. I connected them to a switch so I can control when the lithium battery sees charge current. I haven't had any problems when using 2 different battery chemistries. Don't hesitate and don't waste your money on other brands.
