    Voltage-sensitive isolator vs. simple relay (for house battery)

    Hi there, So all the youtube videos seem to be using voltage-sensitive isolators. But the aux battery guide uses a simple 150-amp relay. The cheapest 140-amp isolator runs about $60, while a 200-amp relay is only $30. From the guide, the relay doesn't look like significantly more work to...
