VEVOR Dual Battery Isolator 12 V 140 A, manual and automatic VSR voltage-sensitive relay with LCD display, suitable for lithium and lead-acid batteries in cars, trucks, campers, UTVs, ATVs, and boats

Features and Information

High battery compatibility: This dual-battery isolator allows you to adjust the turn-on and turn-off voltages, ensuring compatibility with lithium, lead-acid, and other types of batteries. It guarantees optimized charging and helps extend the battery’s service life.

Manual and automatic modes: No worries about starting it up. A voltage-sensitive relay allows you to switch to manual mode with the push of a button so that a fully charged auxiliary battery can recharge the discharged main battery. No jumper cables are needed—you can start the vehicle immediately.

Smart Delay Function: An adjustable delay time ranging from 3 to 60 seconds effectively prevents frequent switching, significantly extending the service life of both the isolator and the battery.

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 charging splitter makes it easy to diagnose circuit problems and reliably monitor the system’s status.

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

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. The real-time voltage display for both batteries allows you to continuously monitor the battery status for safe and reliable use.

Equipped with a high-strength plastic housing, this smart battery isolator offers high impact resistance and effectively withstands collisions. Treated with a special technology, it prevents water and dust from entering.

If the starter battery is dead, there’s 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.
