Need for new vehicles
I'm an amateur radio operator and I utilize a house lithium battery to power the radios. The only way I could get my 2011 F-150 to charge both batteries without causing an issue with the battery management system.And you can't parallel lithium with a flooded AGM or flooded lead acid battery together they must be isolated. I've tried a number of different methods to no avail till I tried the Smart Isolator. And it works just lovely and keeps both the start battery and the lithium house battery fully charged.

Great isolator. Works great in 2016 Polaris Ranger 900-5 Crew.
Ive had this in my Polaris ranger 2016 900-5 crew, for about 8 months. I have 2, 1200 Odyssey batteries installed. This thing works like a champ. It passes the charge to the battery that needs it the most. I tax my system more than most people ever will, and this isolator does more than I need it to. You have to understand your setup and how it all charges or you wont understand how this thing works. I have 2, 54in curved 4D light bars, and 2, 50in curved 4D light bars, along with 2, 7in light bars, and in cab, mulit color lights. I can run all night on my setup. I can hunt 3,000+ acres, for over 8 hours without any issues. I can hear the isolator clicking back and forth, and I can watch my voltage move around. I never drop under 10 volts, on a full load, and that is after all night of hunting. It would of been nice to have longer and better neg and pos. cables, but because of all the other work done to the Ranger, I did have better cable laying around. Others will not have the same luck. So a tip to the seller. Just give the better, longer cables. It wont cost you that much more, and honestly even if it does, I would of paid to have the better cables. Outside of that, I didn't buy this for the cables. I needed the isolator, and it is great quality, and works flawlessly.
