High Compatibility
The dual battery isolator kit automatically adjusts charging voltage according to different battery types. It is widely compatible with various lithium batteries and lead-acid batteries, ensuring that different types of batteries can work efficiently.
Our voltage sensitive relay not only supports flexible voltage adjustment and emergency reverse charging, but also has built-in delay protection to avoid loss from frequent start-stop. Including a real-time display of dual voltages, it keeps you informed of battery status for reliable use.
Featuring high-strength plastic housing, this smart battery isolator provides strong impact resistance to effectively withstand collisions. Treated with special technology, it can avoid the intrusion of water and dust.
Out of power in the starter battery? Don’t worry! Our VSR isolator can be switched to manual mode, utilizing your fully charged secondary battery for reverse charging. It allows you to start your engine without jumper cables and get back on the road in no time!
Specifically designed for dual battery systems, this 12v split charge isolator kit ensures simultaneous charging of two batteries without interrupting the device power supply. Whether in your off-road vehicle, RV, or boat, it provides stable and reliable power support for your devices.

Features & Details

  • High Battery Compatibility: Our dual battery isolator kit can adjust start-stop voltage, compatible with lithium, lead-acid and other battery types. No compatibility worries, it provides optimized charging experiences to maximize battery lifespan
  • Manual & Automatic Modes: No more breakdowns! This voltage sensitive relay enables one-click switching to manual mode, letting your fully charged auxiliary battery reverse-charge a depleted main battery. No jumper cables needed—start the vehicle instantly
  • Intelligent Delay Function: With an adjustable delay time of 3-60 seconds, this VSR isolator effectively avoids frequent switching, significantly extending the service life of the isolator and battery
  • Dual Voltage Display: The high-brightness display shows the accurate voltage of the two batteries in real time (range 4.5V-20V). Our 12v split charge isolator kit can easily diagnose circuit problems and confidently master the system status
  • All-Round Protection: Featuring overvoltage and undervoltage protection, the dual battery smart isolator is sturdy, durable, shockproof, and dustproof. It provides stable and reliable power for your RV, truck, boat, or off-grid system
