Customer Reviews for VEVOR Split Charge Relay Kit, 6mtr 12V, Automatic Dual Battery Isolator Kit with 140AMP Voltage Sense Relay VSR, Compatible with RV Marine Car Vehicle Truck Caravan Camper Yacht ATV UTV Boats Workshop

Have not installed on my truck

I posted the question about the use of a lithium battery with this system and then I did some research and found out that lithium batteries and automobile alternators do not like each other and the lithium battery can damage alternators. I instead got a sealed lead acid battery and after installing the kit found it to be a good setup. I have a light that is 30 wats and on a 12-volt system draws about 2.5 amps. My lead acid battery is 7-amp hour so it should power the light for almost 3 hours with out touching my main cranking battery. I know that my main battery could power the light for 3 hours and still have enough cranking power to start my car but I had it plugged into a cigarette lighter power port and after the car is shut off all the power ports turn of after about 50 minutes. This solenoid system solves both issues. More detailed instructions would be helpful but if you are something close to a “Motor head” you shouldn’t have any trouble installing the kit. The only real problem I had installing the kit came when several of the screws decided that they would rather live in the deep recessed of my engine compartment then the hole they were intended for.

It was very easy to install and there were videos as well online if you did have any problems. I have had it on my pickup for about 6 months and it is still working great

Great kit and very easy to install with minimal experience. A good crimping tool is essential the securing cable end connectors. Works as described. I have independent voltage gauges for each battery. The unit's cut in, cut out voltage was accurate.

Amazed with this product. It works really good. It's not loud at all. Not silent, but as quiet as anyone should expect. Great quality. Is a must have.

I bought it recently and I really recommend this product if anyone need one. Good quality, fair price.

Really needed it came just in time because my old one crapped out on me really happy thank you. All I need is some new batteries but seriously thank you it's real good item

Kit works well and wires are sized right. Because of an unibody car I need an extra long ground cable to finish the installation. Would I buy again, yes.

Great buy you need this if you have speakers and amp hooks up very well when you have an extra battery to run your app and speakers off of with highly recommend Best Buy ever had great customer service great delivery showed up and scheduled easy to track will definitely recommend

The hook up was easy and quick. Just wish that there was a way to connect the two batteries in parallel in case the start battery was dead.
