    Battery switch!

    Why are so many putting in battery switches?
    If you have your PWC battery hooked up for start only. Then your second battery should power everything else for longer than you want to fish.
    I could see putting in a switch if you were running a trolling motor and were carring 2 batteries for it but not for just a few electronics.
    Please let me know?

    Mine was installed as a blue sea add a battery kit with the ACR. The switch is there to allow you to combine the batteries in case you lose your cranking battery and need to combine for emergency starting.

    It's also helpful for completely shutting off the batteries and works well for charging purposes.

    There are multiple configurations of battery 'switches'. Different requirements or differing situations suit different solutions.

    Isolating batteries vs. combining batteries.

    Storage drain vs. on-the-water emergency power, etc.

    I find that sometimes a simple mechanical battery isolation switch is installed when a battery combiner module might be a better solution.

    Heavy duty battery switches route all the main battery power directly through the switch. While this seems simple enough, it introduces a set of switch contacts, extra battery cable end connections, nuts, washers and the switch itself into the battery circuit, thereby affecting the core reliability of the main battery system.

    A battery combiner does not add anything into the main battery cable path, the battery cables remain in factory configuration. The reliability and availability of the main battery should be unaffected. Even if the secondary battery becomes deeply discharged.

    That makes since. Thank you.
