About this item

  • 【NEVER BE STRANDED】The dual battery isolator is connected to both the vehicle's primary and secondary batteries. When the vehicle's primary battery reaches 13.3V, the voltage-sensitive relay automatically switches to charge the secondary battery, and when the vehicle's primary battery voltage drops to 12.8V, the battery isolator cuts off the current flow to the secondary battery, ensuring you always have enough power to start your motor and never get stranded
  • 【SMART BATTERY ISOLATOR】Split Charge Relay has a built-in voltmeter to display the voltage and supports manual/automatic switching, so you can monitor the voltage at any time and switch modes as needed
  • 【EASY INSTALLATION】The VSR split charge relay kit comes with full installation accessories and cables (battery cables, battery terminals, copper lugs, heat shrinks, cable ties ects) All necessary accessoires for convenient use and You don't need to buy extra accessories,that make it easy for users to install it independently to vehicles, boats, recreational vehicles, and other equipment
  • 【SAFE&EFFICIENT 】The dual battery isolator efficiently manages and protects power, preventing over-discharge of the main battery and ensuring full charging of the second battery. With high-quality materials and an IP68 waterproof, dustproof, and vibration-proof construction, our battery isolator delivers reliable performance even in harsh environments
  • 【WIDE APPLICATION】 Like Having Two Separate Power Sources,The Dual Battery Isolator Set Enables Your Accessories to Run From a Separate Battery While the engine is not running on your vehicle While keeping your Main Battery Charged,power up any ground or marine vehicle including ATVs, boats, cars, mini-vans, trucks, RVs, and yachts; Perfect versatile solution for all automotive power needs



Product Description

Smart Dual Battery Isolator Kit

Features:

  • This 12V 140A VSR Voltage Sensitive Split Charge Relay Kit With Cable k seamlessly separates your primary battery from your auxiliary battery, ensuring your engine always has a reliable source of power.
  • The design of the digital voltage display not only facilitates real-time grasp of battery power, but also allows precise control of battery voltage.
  • With an IP68 waterproof rating for all-weather use, this product is the ultimate power solution for all off-road and road trips!

Smart Dual Battery Isolator

  • CUT-IN VOLTAGE: 13.3V
  • DCCUT-OUT VOLTAGE:12.8V DC
  • Voltage Sensitive Relay (VSR) allows charging of two batteries simultaneously. When the engine starts and the starting battery reaches 13.3 volts, the VSR engages, allowing both battery packs to charge simultaneously (Starting Battery Pack and Household Battery Pack).
  • When the voltage drops below 12.8 volts, the VSR disconnects and separating the battery. This reduces the possibility of battery depletion, effectively protects sensitive electronic devices powered by indoor batteries, and extends their service life.

My isolator said the positive for start battery was the wrong post . Direction were correct and other isolators being sold I checked out and the start battery cable goes to the post above the 2 horizontal soldered connection next to the ground wire. The second battery cable goes to the post with vertical silver 1/2in soldered connections. Printing on back of isolator was wrong. Directions are correct

Could have been designed with a step larger cable but so far everything is working great.

Faulty dual battery relay drained my car battery.Constantly, gets stuck in the "on" position, allowing constant power to flow from the starting battery to the auxiliary battery...Even when the vehicle is turned off, essentially creating a huge parasitic drain on my main battery. Defective product...

This is a nice kit with just what I needed to set up a dual battery system in my overlanding rig. It's simple and has good instructions. I also like the built in voltage display - which goes off after a short time to not waste energy.It's important to remember that this is really meant to provide charging current to your "house" battery bank. The interconnection cables are 7 AWG and the included fuses are 60A. This is plenty for charging current. If you're looking for something that can handle load current, you may need a different device.

This kit is amazing to use. You can connect two batteries with this kit. It lets you charge the second battery while the vehicle is running so it will not drain your main battery. This is great if you have a second battery running equipment from your vehicle. It has a display that lets you see the charge rate. It is easy to use, but installing will require some know-how.
