hello guys need some advice I have a 350 5.7 searay, with dual batteries and someone told me why I don't have a battery isolator?, is that a good advice, what is the benefit of that, need some feedback thanks.
A battery isolator usually refers to a device using diodes. Avoid those. The diodes cause .7v of voltage drop and tend to burn out. The ACR (Automatic Charging Relay) is a much better choice. However, 2 batteries can and have been managed for years by many boaters with a simple battery switch. You don't have to have anything else, you just have to remember to put the switch in the right position for the situation.
The advantage of a battery selector switch is that you can run whatever electrical accessories you want, for as long as you want, with the engine off, and when the battery goes dead, you can switch to the other battery and still start the engine.

I did what your discussing and has been on my Rinker since it has been a year old, have had no issues. I also installed a 2-bank battery charger
Agree an ACR does not have the .7V voltage drop and can be connected as such and can be installed with or without a battery charger. An ACR also allows for a single bank battery charger to be used
