Ensure your primary battery is always charged and ready to start your engine, the secondary will be charged after the primary battery’s volts exceed 13.3 volts. Primary Battery Protected: cuts in at 13.3 volts and cuts out at 12.8 volts.Purpose: this voltage sensitive relay is design for two battery systems (SUITABLE for Acid-Lead batteries, NOT SUITABLE for Lithium batteries), allow to having two separate power sources while charging by one alternator, it’s all need to charge and isolate two battery systems.This is why we listed the key features of each of these 12V Battery Isolators below: Since we’ve mentioned 10 different models of 12V Battery Isolators on the above list, it may be difficult for you to find the right one for your needs.
