    Automatic Charging Relay  125A Dual Battery Isolator (VSR) Fully automatic with emergency override Ideal

    A voltage sensitive relay (VSR) is the best way to ensure you can always get your dual-battery vehicle started.
    If the radio stops working that’s one thing, but if you’re stranded because your car cannot start because you 
    ran your fridge for too long, that’s potentially a life and death scenario. It allows two batteries to be charged 
    from your alternator. Once your main starter battery is sufficiently charged, it will begin charging the second battery too. 
    Fully automatic with emergency override.

    Automatically combines two batteries when charging and isolates the two batteries when not charging.
    No voltage drops comparing to battery isolator diodes (0.6V).
    Dimensions fits Heavy Duty Modular Fuse Box Series (BF43x) and Battery Switch, matching mainstream products in market 

    Built-in LED indication (ON when VSR engages)
    Port for remote LED indicating VSR status (LED not included)
    (If the VSR equipment is installed in a place that is difficult to see,
     it can be installed by an external indicator light, installed in a place that the operator can easily see,
     such as the instrument panel, and the negative pole of the external light is connected to the black line to be cut on the VSR equipment.)

    Surface or panel mount options provides flexibility when installing
    Optional Storage Mode allows zero power consumption when engine is off.
    (When you do not need this device (VSR) function, you can cut off the red line and connect an ON-OFF switch to control the device's power off.
    Normally, if the boat or yacht is not used for a long time, turn off the VSR to achieve zero power consumption when it is not used for a long time)

    Functional Features Example: 
    After the engine stalls, the left House battery discharges to the upper left load device,and the VSR disconnects when the battery voltage drops below 12.8V.?
    The Start Battery on the right will not discharge to the device
    When the battery on your left is not charging, it is used up.
    At least there is a little battery on the right that allows you to start the engine
