Dual Battery Isolator Kit, 12V 140A Voltage Sensitive Relay for Two Battery Systems

This dual battery isolator kit uses a voltage sensitive relay so one alternator can charge two 12 V battery systems while keeping them separate. The primary battery is connected first, and the secondary battery charges once the primary battery's voltage rises above 13.3 volts. Designed for acid-lead batteries and not suitable for lithium batteries.

Suited to cars, vehicles, RVs, ATVs, UTVs and boats, as well as other two-battery 12 V equipment. The kit includes the relay, red and black battery cables, 3 battery terminals, 3 copper lugs, heat shrinks, cable ties and 4 bolts for installation.
