【Function】——Voltage Sensitive Relay(VSR) cuts in at 13.3v and cuts out at 12.8v to ensure your main battery is always charged and ready to run your vehicle. The dual battery isolator can display the voltage, you can check the battery voltage in time 【Secure & Effective】——When the input voltage is lower than 11V or more than 17V, the circuit will be disconnected automatically to protect batteries. IP67 waterproof rating helps smart battery isolator perform well in extreme environments 【Wide Compatibility】——This 12v battery isolator is small and suitable for almost anywhere, for ATV, UTV, Boats, RV, marine, vehicle, truck and caravan. 140amp battery isolator is very useful for storing sports cars and trailers to protect batteries from drained 【Emergency Condition】——The VSR can reverse charge in both manual and automatic modes. For example, when the main battery is out of power, switch to manual mode to connect the circuit, the auxiliary battery can charge the main one in reverse 【After-sales Service】——We have exquisite craft, strict quality control along with excellent after-sales service. That is why our products are worthy of your purchase
Note:
Please allow 1-3CM differs due to manual measurement.
Due to different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding.
1.Manual and auto modes
① Long press the "Select" button for 3 seconds - the blue (LED) indicator will be ON, the manual mode is on.
② Long press the "Select" button for 3 seconds - the blue (LED) indicator will be OFF, the auto mode is on.
2. Manual state use function
The blue indicator light is ON, press the button each time, you can complete the circuit connection and disconnection.
The circuit switched on the red indicator , the voltmeter lights up at the same time.
The circuit disconnect red indicator light, the voltmeter goes out at the same time.
3.Automatic state use function
① When the input voltage exceeds 13.3V, the circuit will be connected automatically. The voltmeter and red (LED) indicator will also be ON.
② When the input voltage drops to 12.7V, the circuit will be disconnected automatically. The voltmeter and red (LED) indicator will also be OFF.
4.High & low pressure protection
① When the input voltage reaches lower than 11V, the circuit will be disconnected automatically to protect the main battery from over discharging.
② When the input voltage reaches more than 17V, the circuit will be disconnected automatically to protect the secondary battery from high voltage impact.
5.Voltmeter display
① If two batteries are connected, then the voltage displayed on the voltmeter is the battery that has higher voltage.
② Only connect the battery that you would like test the voltage and disconnect the other battery.
③ When the voltmeter is not working, press the button once, the voltmeter will display the value for 2 seconds.
