VEVOR Dual Battery Isolator, 12V 140 Amp, Manual and Automatic VSR Voltage Sensitive Relay with LCD Screen, Smart Battery Isolator for Lithium & Lead-Acid Batteries, for Car Truck RV UTV ATV Boat

Manual and Automatic VSR Mode for Emergency Reverse Charging Without Jump Cables

Both automatic and manual voltage-sensitive relay modes are available with this smart dual battery isolator. The isolator operates independently in automatic mode. When necessary, it connects or disconnects batteries based on voltage variations. The driver does not have to change settings or press buttons. For everyday use and regular driving, this mode is perfect.

In an emergency, manual mode provides more control. Users only need to press a button to switch to manual mode if the primary battery starts to weaken. The primary battery then receives power from the auxiliary battery. Without jumper wires, reverse charging can start the car. It prevents roadside delays, saves time, and lowers stress.

12V 140A Dual Battery Isolator Supporting Lithium and Lead-Acid Batteries

With a 12V 140A capacity, the smart dual battery isolator provides robust, reliable power regulation. It can manage large electrical loads stress-free, thanks to its high current rating. Lithium, lead-acid, and other common battery types are compatible with it. Users do not have to worry about damage or charging problems when connecting dual batteries to a single system. Because of this, it is beneficial for contemporary cars with diverse battery systems.

Depending on the battery type and voltage level, the isolator regulates charging. When limits are reached, it stops charging and sends electricity where it is needed. This procedure stops deep discharge and overcharging. Batteries perform better and live longer as a result. With a steady and dependable power supply, the system can handle extended excursions, daily driving, and off-grid use.

Adjustable 3 to 60 Second Intelligent Delay Function to Prevent Frequent Switching

The isolator has a built-in delay that can be set to 3-60 seconds. This delay keeps the relay from moving too often when the voltage changes. When the engine starts or when electricity loads change, voltage can change quickly. The delay gives the machine time to think before it acts.

This feature covers the smart dual battery isolator and the batteries connected to it. When there are fewer switching processes, parts inside wear out faster. Batteries also remain more stable while charging. This ensures power control operates smoothly and extends the life of isolator systems in cars, RVs, and off-grid systems.

Dual Battery LCD Voltage Display Showing 4.5V to 20V Instant Readings

A clear LCD screen displays the current voltages of both batteries simultaneously. The screen's voltage measurement range is 4.5V to 20V. Users can tell right away what is wrong with the battery by looking at it. The screen is bright and easy to read outside, even in low light.

With this real-time display, users can quickly identify problems. Problems with charging, battery imbalance, and low power are easy to see. With the dual battery isolator, you do not need any extra testing gear, and it reduces the risk of measurement errors. There is more power in the hands of technicians and drivers.

Smart Voltage Sensitive Relay for Optimized Charging and Extended Battery Life

The voltage-sensitive relay continuously monitors the battery voltage. When charging is safe, it links the batteries; when the voltage drops, it disconnects them. This automated control makes sure the auxiliary battery charges correctly and safeguards the starter battery.

Without wasting energy, the smart dual battery isolator balances charging. Batteries always maintain a safe voltage range. This lowers power loss, heat, and stress. Batteries maintain their capacity over time and work reliably under both daily and high-use circumstances.

Overvoltage and Undervoltage Protection for Safe 12V Power Management

The isolator has built-in safety against both overvoltage and undervoltage. When the voltage reaches unsafe levels, these safety mechanisms cut off the power flow. Overvoltage protection guards against damage from overcharging. Protecting against undervoltage prevents deep battery drain.

The entire 12V system remains stable thanks to the dual battery isolator. Sensitive devices are shielded against unexpected voltage decreases or spikes. This safety level supports long-term use in automobiles, boats, and off grid configurations where power stability is crucial.

Shockproof and Dustproof Housing Designed for Harsh Mobile Environments with Smart Dual Battery Isolator

The isolator has a robust casing that is resistant to dust, vibration, and shock. It works well in marine environments, off road use, and other challenging driving conditions. Internal parts remain safe even in severe weather or on rough roadways.

The dual battery isolator can operate reliably for extended periods thanks to its sturdy construction. It withstands dirt, moisture, and vibration. In demanding mobile power systems, users can install them with confidence.

Wide Vehicle Compatibility for Car, Truck, RV, UTV, ATV, and Marine Systems with Smart Dual Battery Isolator

Numerous vehicle types, such as cars, trucks, RVs, UTVs, ATVs, and boats, are compatible with this isolator. It easily adapts to marine and automotive electrical systems. Without requiring complicated wiring modifications, the design enables seamless integration.

The dual battery isolator is ideal for off-grid power needs, work vehicles, and camping. It provides consistent power control for a variety of uses. Because of its broad compatibility, it is an excellent option for users who require reliable dual-battery management across a variety of settings.
