So I've been looking at getting an isolator that will prevent spikes to my electronics upon starting, and is easy to install. The BEP 716 unit look good, as does the Blue seas "add a battery" unit. Anyone have any experience with these? I'm concerned that the Blue seas unit requires a connection off the alternator. The BEP appears to have that function built in.

I have read lots of good things about the Blue Seas "Add a battery" setup - you put your "house" electronics (fish finder, lights, radio, etc, etc) on one battery and your cranking motor on the other - then this little box has a relay inside that lets your motor charge your cranking battery when running, and once it reaches a full charge it will flip to the house battery and charge it. Overall a smart setup.
Familiar with BEP, and they have a good reputation - just not familiar with the 716 unit.

I thought more folks would be using some sort of battery combiner that allows the boats alternator to switch over and charge backup batteries, trolling motor, or bait tank batteries.

Mine is setup with the Aux charging cable on the motor. Many of the Yamaha's have a Aux charging cable (that is sometimes not connected at the batt or the motor) that will charge a second battery when running. I use this to charge the battery that my electronics are running off of. Not the same thing as the isolator / relay as those change one then flip over when the main batt reaches a certain level and will charge the 2nd. The Aux charging cable, as I understand it, charges both at the same time when running (but does not try and crank off the Aux batt, so if you want to use that as a backup then you need a batt switch).
Of course I also keep a multi-bank battery to charge everything when off the water.
