The Dual Sensing Smart Battery Isolator monitors both the starting battery and the auxiliary. If the unit detects that either battery has exceeded 13.2 volts, then the isolator will connect them. The benefit of the dual control enables the user to charge the main battery from a solar panel or battery charger on the auxiliary battery. When the entire battery system drops below 12.7 volts the solenoid opens and isolates the starter battery from the auxiliary battery. This ensures you never have a drained starter battery again.
Features:
- A safe way to charge your auxiliary battery while driving
- Cost-effective protection against a flat start battery
- The Smart Battery Isolator monitors both battery voltages
