Review on BEP Digital Voltage Sensing Relay by Wes Thao

Revainrating 5 out of 5

The Best Battery Isolator Out

Keeps your extra battery charged and isolated with no voltage drop. The old-school double diode isolates 0.7V between both batteries due to the diode contact resistance. Can be connected to a remote switch to turn off and to a remote LED to monitor operation. I've had one on my boat for years and now on my pickup truck and they work perfectly.

Pros
  • Good Thing
Cons
