Dual Battery Isolator Kit

• ZERO VOLTAGE DROP: Forget the traditional diode relays and so-called "solid-state" devices that can rob you of almost 2 amps of output power! The Dual Battery Isolator is the only unit designed with cutting-edge programming to deliver optimum performance - with ZERO sacrifices. This compact battery isolator was built ultra-small (2.6" x 2.6" x 2") to fit almost anywhere! A perfect fit under the hood to get close to your dual batteries.

​​

• VOLTAGE SENSITIVE RELAY: The KeyLine AUtomative 140 Amp Dual Battery Isolator is all you need to charge 2 battery systems. Voltage Sensitive Relay (VSR) cuts in at 13.3 volts and cuts out at 12.8 volts to ensure your primary battery is always charged and ready to start your vehicle. It's like having 2 separate power sources for each battery while only having one alternator! 

​​

This International Protection rating means that your KeyLine isolator is safe for use even for your off-road needs in dusty, wet, and unexpected extreme weather environments. Great for extreme vibration applications as well.
