12V VSR 125A Voltage Sensitive Relay Automatic Charger Waterproof Relay Battery Isolator for Camping Smart Car Auto Parts

ZERO VOLTAGE DROP : Forget about traditional diode relays and so-called “solid state” devices that can rob you of nearly 2 amps of power output! The Dual Battery Isolator is the only unit designed with cutting edge programming to deliver performance – with no compromise. This compact battery isolator is built so small (2.6″ x 2.6″ x 2″) it fits almost anywhere! Perfectly fits under the hood to get close to your dual batteries.

VOLTAGE SENSITIVE RELAX : The 125 Amp Automatic Dual Battery Isolator is all you need to charge two battery systems. The voltage sensitive relay cuts off at 13.3 volts and disconnects at 12.8 volts to ensure your primary battery is always charged and ready to start your vehicle. It’s like having two separate power sources for each battery while only having one alternator!

Rugged Durability : Unlike other isolators on the market, the Automatic 125 Amp Dual Battery Isolator is IP65 certified. This international protection rating means that your isolator is safe to use even for your off-road needs in dusty, wet and unpredictable weather environments. Great for extreme vibration applications as well.

EASY TO USE: The 140A Dual Battery Smart Isolator comes with mounting plate and hardware.
