Dual Battery Isolator - 150 Amp

Wirthco's new state-of-the-art, fully automatic dual battery controller is suitable for any vehicle with an auxiliary battery.

Wirthco's high-performance electronic isolator allows you to charge two batteries from a single alternator, and keeps the starting battery isolated from the second battery. Also, with a single push of the override/reset button, you can change the batteries to parallel mode for jump starting.
