Description:
A VSR is a relay that separates the car's main cranking battery and the secondary accessories battery. The VSR is triggered by detecting when the alternator is running and charging the car battery. When the VSR detects that the car is on, it says "Hey the car's on! OK let's connect the two batteries". Thus, your secondary battery starts charging.

The advantages of a VSR are that you get the potential full advantages of a dual battery system, that a) if the car is off and you're powering accessories, you won't drain your main battery, and b) if you need (in a pinch) to use your auxiliary battery to crank the car, you can override with the click of a switch.

Prevents you from draining the starter battery.
Automatically combines two batteries when charging and isolates the two batteries when not charging.
