Description

The Dual Battery Sensing 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 sensing feature allows user to charge the main battery from a solar panel or an external battery charger, on the auxiliary battery, once the auxiliary battery reaches 80% state of charge (13.2V). This ensures you never have a drained starter battery again. The isolator is also automatic and based on voltage, which saves installation time. When the entire battery system drops below 12.7 volts the solenoid opens and isolates the starter battery from the auxiliary battery.
  • A safe way to charge your auxiliary battery while driving
  • Cost-effective protection against a flat starter battery
  • The isolator monitors both battery voltages
  • The optional Manual Switch allows for manual control, linking the two batteries together with a push of a button. The isolator will manually operate allowing current to flow for 60 seconds without the alternator even if both batteries are below 12.7V.

Once either battery voltage reaches 13.2 volts, the solenoid automatically connects the auxiliary battery to the charging system.

  • A safe way to charge your auxiliary battery while driving
  • No need to tie to ignition, save installation time
  • Ability to use an external charging device to charge main battery through aux battery
  • Cost-effective protection against a flat start battery
  • The isolator monitors both battery voltages

The optional Manual Switch allows for manual control linking the two batteries together with a push of a button. The isolator will manually operate allowing current to flow for 60 seconds without the alternator even if both batteries are below 12.7V.
