Dual Battery Isolator Install (Step by step)

Step by step Battery Isolator install (12V 140 Amp Dual Battery Isolator by KeyLine Chargers - Voltage Sensitive Relay (VSR) Pro Dual Battery Kit). This isolator kit connects the starter battery in your vehicle to a secondary “house” battery. The isolator tests for a proper charge level from the starter battery prior to charging the 2nd battery. If the starter battery falls below the starting threshold the isolator will shut off so that the starting battery still retains enough starting power, and does not get drained. I've found it to be a better investment than solar, and if I had it to do over again I would do the isolator first, and then add solar panels. This system also allows for powering the auxiliary battery with a solar panel with a charge controller. This facilitates long-term boondocking by providing power for your electronics.
