12v batteries relay in comparison

12V 140amp voltage sensitive intelligent Split Charge Relay

Frequency adjustable Adopt advanced chip technology. Flash relay speed adjustable. Adjust the bottom knob with a flat-blade screwdriver, and set the blinking speed to 50c m 200c m. 3 frequencies, counterclockwise rotation is faster, clockwise rotation is slower.

Powered by 12V car battery

Manual State Use Function In manual model, you can complete the circuit connection and disconnection by pressing the blue indicator button each time. When the circuit is switched on, the red indicator and voltmeter will light up. When the circuit is disconnected, the red indicator and voltmeter will go out.

(EVERYTHING REQUIRED FOR YOUR KIT) - ALL PARTS ARE SUPPLIED AND NO ADDITIONAL PARTS ARE REQUIRED. SIMPLY FIT BETWEEN YOUR MAIN BATTERY AND LEISURE BATTERY AND THE VSR WILL MANAGE CHARGING YOUR LEISURE BATTERY AND ENSURE THAT YOUR MAIN BATTERY NEVER GOES FLAT

With LED Display The split charge relay kit has an LED display that can clearly display the voltage. It is widely suitable for most 12V cars, caravans, SUVs, trucks, RVs, SUVs, RVs, ATVs, UTVs, ATVs, UTVs, boats, etc.

LED SCREEN REAL-TIME VOLTAGE DISPLAY This dual battery isolator is constructed with a voltmeter which will display the real-time voltage, allowing you to control the battery status at any time. If you connect 2 batteries, then the voltmeter will display the battery that has high voltage. The smart battery isolator is universal fit for truck, UTV ATV, boat, marine, bus, etc.

The lighting design is not afraid of the dark, making it more convenient to detect car relays with just one click to turn them on

VOLTAGE SENSITIVE RELAY Automatic Manual 140 Amp Dual Battery Isolator is all you need to charge Two Battery Systems. Voltage Sensitive Relay (VSR) cuts in at 13.3V and cuts out at 12.8V to ensure your primary battery is always charged and ready to start your vehicle. It's like having two separate power sources for each battery while only having one alternator!

Energy-saving Anti-theft The remote battery isolation switch has a rated current of 240A and a rated voltage of 12V. It consumes only 3mA of standby current and shuts off at the shutdown threshold of 11.9V 0.2V to prevent battery drain, ensure safety, and facilitate maintenance of the vehicle's electrical system. The kill switch effectively protects and extends the life of the car battery.

Versatile applications This compact, automatic 140 amp dual battery isolator is all you need to charge two batteries virtually anywhere, including ATVs, UTVs, boats, motorhomes, watercraft, trucks and caravans.

Fitment is recommended by an auto electrician or tow bar fitting centre
