Our take on the VEVOR Dual Battery Isolator Kit, 12V 140Amp, Manual and Auto Modes VSR Voltage Sensitive Relay with LCD Screen, Smart Battery Isolator

The VEVOR VSR002 is a 12V dual battery isolator that combines a voltage sensitive relay with manual and auto modes. It connects a starting battery to an auxiliary battery and only links them once the main battery is charging, so accessories run off the second battery without draining the one that starts the engine. An LCD screen shows live voltage, and the 140A rating covers winches and other heavy loads for short bursts. It suits ATV, UTV, RV, camper, boat and off-road builds where a simple, self-switching isolator is wanted; it is a basic smart relay rather than a DC-to-DC charger, so it does not boost charge voltage the way pricier chargers do.

Best forRV, camper and caravan dual-battery setupsATV, UTV and off-road vehicles with a second batteryBoats and yachts running accessories off a house batteryOwners who want automatic switching plus a manual override
Pros
  • Automatic cut-in and cut-out switching, no manual relay to remember
  • Manual mode for overriding the automatic logic
  • LCD screen shows battery voltage at a glance
  • 140A rating handles winches and heavy short-burst loads
  • Works on any 12V lead-acid storage battery system
Cons
  • 140A is a short-duration rating, not continuous
  • Cut-in and cut-out thresholds are close, so switching can cycle near the limits
  • No DC-to-DC charging, so a depleted auxiliary battery charges slowly
  • Voltage-only switching can leave a lithium auxiliary undercharged

Questions and answers

How does the automatic mode decide when to connect the batteries?
It links the two batteries once the main battery reaches the cut-in voltage of about 12.3V, meaning the alternator is charging. It disconnects when voltage falls to the cut-out level of about 12.6V, so the starting battery is protected.
Can it handle a winch?
The 140A maximum is rated for up to 5 minutes, which covers short winch pulls. For long, repeated pulls, check the winch's continuous draw against that limit.
Will it work with a lithium auxiliary battery?
It switches on voltage alone, so a lithium battery may not reach a full charge from it. A DC-to-DC charger is the better match for lithium house batteries.
What is manual mode for?
Manual mode lets you force the batteries to connect or stay separate, useful for winching or for isolating the auxiliary battery when parked.
Does it work on 24V systems?
No. It is built for 12V storage battery systems only.
