Deck Tech 12V Voltage Sensitive Relay (VSR) - 140A
The Voltage Sensitive Relay (VSR) connects & disconnects the auxiliary battery from the starting battery based on its current level of charge.
With the engine running the VSR will engage when the starting battery reaches 13.3 Volts and the LED light will illuminate.
This means that both batteries are now linked and th system is working.
Once you turn off your vehicle the system will disengage the two batteries as it reaches 12.8 Volts, leaving your main battery safe to start again.
