The VEVOR split charge relay kit is a voltage-sensitive dual battery isolator for 12V vehicle systems. It connects the starter and auxiliary batteries so both charge while the engine runs, then separates them when voltage drops so the starter battery stays charged. The 140A continuous rating and IP65-sealed housing suit campers, 4x4s and vans running fridges or inverters. It is a simple electromechanical relay, not a DC-DC charger, so it will not manage lithium charging profiles.

This is a 12V dual battery isolator kit built around a 140A voltage-sensitive relay. It charges two batteries at the same time. When the vehicle is turned off, it isolates them from each other.
The relay has an IP65 waterproof rating and a compact body. It switches on at 13.3V and off at 12.8V. The kit includes installation accessories and instructions. It is not suitable for lithium batteries.
