The VEVOR Dual Battery Isolator is a 12V, 140-amp relay-style isolator that keeps a main and auxiliary battery charged separately and lets you link them when needed. An LCD screen shows both battery voltages in real time, and it works with lithium and lead-acid batteries, adjusting charging voltage to the type. It offers manual and automatic modes, including a reverse-charging mode that connects the batteries to start a vehicle without jumper cables. A delay function limits frequent switching to protect the relay and batteries. It suits overlanders, van and boat owners, and anyone running a second battery for accessories.
