Lengthen the Life your Batteries
When two vehicle batteries are wired in parallel they have a tendency to charge and drain one another. Installing a relay that disconnects the batteries when the engine is off prevents excessive wear and lengthens the life of the batteries. Whenever you turn your engine back on, the batteries will be connected without any voltage drop to the second battery.

Ideal for battery isolation,Huarew's high current relays are the most reliable and efficient way to add secondary batteries to your system. Compatible with all types of alternators and charging systems, simply connect these relays to operate when the ignition is turned on. The battery systems remain separate while the ignition is off, preventing system drain. Water resistant black phenolic plastic, 100,000 mechanical cycle life.

The HUAREW Isolator is the perfect solution when adding a secondary battery to your audio system. It allows the second battery to be fully dedicated to the sound system and does not create a voltage drop like common isolators tend to do. The isloator will draw less than 1 amp when your vehicle is powered on. All of this will ensure that your battery will be isolated with confidence!

Perfect for any application with multiple batteries that need to be isolated including Marine, Mobile Audio, Off-Road, Power Sports, and more.
