Forget the traditional diode relays and so-called "solid state" devices that can rob you of almost 2 amps of output power! The Keyline dual battery ATV/UTV Isolator is the only SMART unit designed with cutting edge programming to deliver optimum performance - with ZERO sacrifice. 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 or in your offroad rig to get close to your dual battery setup.
VOLTAGE SENSITIVE RELAY: The KeyLine Automatic 140 Amp Dual Battery Isolator is all you need to charge Two Battery Systems in your ATV/UTV vehicle.

It's like having two separate power sources for each battery while only having one alternator!
