• This kit allows you to run powerful accessories (fridges, camp lights, inverters) in your vehicle from an auxiliary battery without draining your main starting battery.
• 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 13.1 Volts and the LED light will illuminate.
• This means that both batteries are now linked and the system is working. Once you turn off your vehicle the system will disengage the two batteries as it reaches 12.7 Volts leaving your main battery safe to start again.
• This kit comes complete with installation instructions, it’s easy to install with no change to vehicles original wiring.
