These Smart Battery Isolators are designed specifically for use in multi-battery applications. The XSBi series of isolators primarily monitors the main starter battery voltage. Once the starter battery voltage reaches 13.2 volts, the solenoid automatically connects the auxiliary battery to the charging system. When the whole system drops below 12.7 volts, the solenoid opens and isolates the starter battery from the auxiliary battery. This ensures you should never have a drained starter battery again.
