I installed thus yesterday. Looking at the other reviews I see that this unit is known to fall after 6 months or so. I will update my review if that should happen. For now I am happy as the included 15 feet of 2 AWG wire is worth the price of the unit… I mean you’d just about pay $50 just for that much 2 AWG wire!

So far product seems to be working well. Installation diagram and instructions are pretty clear. Have connected this to charge my starter bank West Marina dual purpose, and the house battery, Renogy 200AH AGM. Will update review again in some time as it progresses

It keeps my backup battery charged and ready to go for my RV trailer’s power when boon docking. Plus it can be used to jump my main battery if needed. Obviously you need some technical and automotive electrical skills to properly hook it up. The Avalanche I own already had a place for a spare battery and the wiring was already there to provide power to the trailer.

I’m a marine technician who installs similar systems on various types of boats. This was super easy and worked great. Good quality components

This is an update to my previous review. It appears well made, and actually worked very well in my truck.
As a potted more or less solid state device I figured I’d get years of service out of it, but on 19 August 2023 it stopped working and wouldn’t charge my other battery, it just clicks constantly. Anyway warranty is 6 months, mine quit at just over 7 months.

Was easy to install and easy to hook up my accessories in my can am commander 4 seater sxs. Haven’t had my primary battery die since installing this. Would definitely recommend to a friend and purchase another one if I ever need to too.

I have this on my pontoon boat between 2 24 series batteries that are both brand new. They also both have a solar charger on each of them. One is strictly a starting battery and the other is a deep cycle to run the accessories. I can only listen to the stereo on my boat for about 15 minutes which I am guessing the amount of power from the solar charger. Going to just eliminate this and hook them up in parallel so they both get recharged. Don’t waste your money!
