This VSR battery switch is for dual battery systems. This voltage sensitive relay isolates one battery for starting and then switches to the 2nd battery to run all on board systems thus insuring a fresh battery for starting at all times. Will charge both batteries while the engine is running. Super simple installation. $95 o.b.o
