VEVOR Dual Battery Isolator Kit, 12 V, 300 A, with manual and automatic VSR voltage relay, voltmeter, and LCD screen, smart battery isolator for lead-acid batteries in UTVs and ATVs

Features and Details

High battery compatibility: With a current rating of 300 A, this two-battery isolator kit is the optimal charging solution for high-capacity two-battery systems. The turn-on and turn-off voltages are adjustable; compatible with lithium, lead-acid, and other types of batteries.

Manual and automatic modes: No more unexpected stoppages. This voltage-sensitive relay allows you to switch to manual mode with the push of a button, using a fully charged auxiliary battery to charge the main battery. No jumper cables are needed—the vehicle can be started immediately.

Smart Delay Function: An adjustable delay time of 3–60 seconds effectively prevents frequent switching, significantly extending the service life of the isolator and the batteries.

Dual voltage display: The high-brightness display accurately shows the voltage of both batteries in real time (range: 4.5–20 V). This 12-volt split-charge isolator kit makes it easy to diagnose circuit problems and safely monitor the system’s status.

Comprehensive protection: Equipped with overvoltage and undervoltage protection, the smart dual-battery isolator is durable, impact-resistant, and dustproof. It provides a stable and reliable power supply for RVs, trucks, boats, or off-grid power systems.

The dual-battery isolator kit automatically adjusts the charging voltage to suit different battery types. It is widely compatible with various lithium and lead-acid batteries, ensuring efficient and stable operation of different battery types.

Our voltage-sensitive relay provides flexible voltage regulation and emergency reverse charging, and is equipped with built-in delay protection that prevents losses caused by frequent switching on and off. Real-time dual-voltage display allows for continuous monitoring of the battery’s condition, ensuring safe and reliable operation.

This smart battery isolator features a high-strength plastic housing that provides excellent impact resistance and effectively protects against collisions. Thanks to a special coating technology, water and dust are prevented from entering the device.

Is your starter battery dead? No need to worry. Our VSR isolator can be switched to manual mode, using a fully charged auxiliary battery for reverse charging. This allows you to start the engine without jumper cables and get back on the road quickly.

This 12 V split-charging isolator kit is specifically designed for two-battery systems, ensuring that both batteries are charged simultaneously without interrupting the power supply to your devices. Whether used in an off-road vehicle, a camper, or a boat, it provides a stable and reliable power supply for your devices.
