Review: Great smart battery isolator for van builds. - 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.
Review: overlanding piece of mind - this charging relay is awesome, it really makes the dual battery setup shine. I venture out 3-4 hours one way outside of any cell phone coverage often, this charging relay with a second battery puts my mind at ease. on my last trip and first time using this setup I latched the two batteries together for the 4 hour hwy portion. once I hit the dirt I unlatched the two batteries till I hit pavement again a couple of days later. generally I leave the remote switch in auto mode in the city. this charging relay is smart and does all the thinking for you. I am an land/marine electrician and woods adventurer and can't recommend this unit enough, just buy it and be done!

### ⭐⭐⭐⭐⭐ 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.
