## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to install
*by J***M on June 13, 2025*

High quality product. Easy to install

### ⭐⭐⭐⭐⭐ Great smart battery isolator for van builds.
*by S***S on November 22, 2024*

I installed this smart battery isolator 3 years ago in my van, and so far it's been working flawlessly. I really like the fact that it allows the charge direction to switch automatically depending on my charging source, and it keeps the house and vehicle batteries fully charged. I do a lot of off-grid camping in remote areas, so the ability to use the house batteries to jump start the engine (if vehicle batteries are low) is important.

### ⭐⭐⭐⭐⭐ Best battery isolator I’ve ever had
*by F***S on August 26, 2024*

Bought this for my class B camper. I’ve had it installed for about two months and it works great. The auto feature disconnects you from the battery and connect you. The latching feature works good. I checked current and it’s pulling less than 0.1 of an amp. The control switch is also an indicator for latch unlatch.
