VEVOR Dual Battery Isolator 12 V, 300 A, with manual and automatic VSR voltage-sensitive relay and LCD display, suitable for lithium and lead-acid batteries in cars, trucks, campers, UTVs, ATVs, and boats

Features and Details

High battery compatibility: With a current rating of 300 A, this dual-battery isolator is the optimal charging solution for high-capacity dual-battery systems. The start-stop voltage is adjustable; compatible with lithium, lead-acid, and other battery types.

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

Intelligent delay function: With an adjustable delay time ranging from 3 to 60 seconds, the VSR isolator effectively prevents frequent switching, significantly extending the service life of the isolator and the batteries.

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

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

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

Our voltage-sensitive relay not only provides flexible voltage regulation and emergency reverse charging, but also features built-in delay protection that prevents losses caused by frequent start-stop cycles. The real-time dual voltage display allows you to continuously monitor the battery’s condition, ensuring reliable operation.

Equipped with a high-strength plastic housing, this smart battery isolator offers excellent impact resistance and effectively withstands mechanical shocks. Thanks to its special finish, it protects the device from water and dust ingress.
