Dual battery charging made easy! Allows two or more batteries to be charged at the same time. When the battery reaches 13.7V the relay closes allowing the second battery to be charged. When the engine stops and the voltage on the sensed battery drops to 12.8V the relay opens and isolates the two banks. Unlike standard battery isolators, there is no voltage drop, and each battery receives a full 13.7V charge. This Isolation system does not use the engine alternator, works strictly off battery system. Rated for charging systems up to 100A.
Dimensions: 2-3/4"L x 2-3/4"W x 2"D.
