12V 140 Amp Smart Dual Battery Isolator Voltage Sensitive Relay (VSR) Pro
- 12V, 140A, 13.3V cut-in voltage, 12.8V cut-out voltage, Suitable for 12V 4WD, marine, truck, caravan & camping applications
- If you need to isolate your vehicle's starting battery from its auxiliary battery, this SCA dual battery isolator kit is an easy to install option. You can use it with your 4WD, marine vehicle, truck, caravan, or for camping applications. The battery isolator is surge protected, keeping your vehicle and battery safe from unexpected surges.
- When the engine is started, starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.3 volts the Voltage Sensitive Relay engages allowing both starting and auxiliary batteries to be charged. This is indicated by the red light in the top LH corner being illuminated.
- When the engine is stopped and the battery voltage falls below 12.8 volts the VSR disengages separating the start and auxiliary batteries, at this point the indicator light will be out and the auxiliary battery continues to power any accessories without risk of draining the starting battery.
- No alternator or ignition connection needed
