I heard from my brother that people who install high power sound systems often get a high voltage alternator to power it without killing the starter battery. I was thinking about this for my electrical system. I’d like to get a deep cycle house battery and isolation/charging circuit for it. Does anyone have experience doing this kind of conversion? Or recommendations for alternators and charging circuits?

    Also keep in mind that sitting idle with the engine running to charge off the alternator adds more wear to the engine and is also less efficient than running a generator which is designed for the task.

    An engine just sitting idle isn’t going to distribute oil to all it’s parts well. It’s also got no air flowing around it aside from what the fan provides so things are going to get hot!
