A 12V dual battery isolator kit built around a 140A voltage sensitive relay, with manual and automatic modes and a dual voltage display. The adjustable 3–60 second delay cuts relay chatter, and the manual mode lets a charged auxiliary battery back-feed a flat main battery without jumper cables. It suits overlanders, RV and boat owners, and anyone running a second battery for a fridge or winch. Against simpler fixed-threshold VSRs it adds a display, delay tuning and start-stop voltage adjustment; it is a bulkier, wired-in unit rather than a plug-and-play module.

Owners of dual-battery setups generally rate the kit on its display and manual override, and note the install takes planning. Some find the settings menu and wiring instructions need care.
The VEVOR dual battery isolator kit is a 12V, 140A voltage sensitive relay (VSR) that links a main battery and an auxiliary battery. It has an adjustable start-stop voltage and works with lithium, lead-acid and other battery types. It can be used in an RV, truck, boat or off-grid system.
It runs in automatic or manual mode. In manual mode, one click lets a fully charged auxiliary battery reverse-charge a depleted main battery, so jumper cables aren't needed to start the vehicle. The delay time is adjustable from 3 to 60 seconds, which avoids frequent switching.
A display shows the voltage of both batteries in real time, in a range of 4.5V to 20V. The isolator has overvoltage and undervoltage protection. It is shockproof and dustproof, and the housing is made of PA6 plastic.
