Manual/Auto VSR Smart Dual Battery Isolator with Voltmeter

Manual Control

Activate the manual mode by long-pressing the button for 3 seconds. Easily connect and disconnect the circuit with a simple press of the button, indicated by the red indicator and voltmeter. Ensure complete control over your battery system.

Automatic Control

Switch to the auto mode by long-pressing the button again. The circuit will automatically connect when the voltage exceeds 13.3V, indicated by the voltmeter and indicator lights. When the voltage drops below 12.8V, the circuit will disconnect, preserving battery power.

Real-time Voltage Display

Our dual battery isolator features a built-in voltmeter that provides accurate and real-time voltage readings. It intelligently displays the voltage of the higher-charged battery when two batteries are connected. Suitable for various vehicles, including trucks, UTV/ATVs, boats, marine vessels, and buses.

Voltage Sensitive Relay

With a cut-in voltage of 13.3V and a cut-out voltage of 12.8V, our isolator ensures that your main battery remains charged, eliminating worries of battery drain and getting stranded on the road. Enjoy convenient and reliable operation.

Pressure Protection

To safeguard your main battery from over-discharging, the circuit will automatically disconnect if the input voltage is below 11V or exceeds 17V. This protection feature ensures the longevity and optimal performance of your battery system.
