    im putting together a pretty powerful audio system (Soundstream class A 10.0 and a Pheonix Gold ZX450) and will want to do a dual battery setup with an isolator. I was just wondering if anyone has done this and have pics of the setup. Any tips are appreciated. Thanks

    you can use an isolator but i have done many installs and never used one. the shop i worked at didnt like using them. never had any issues with not using one. so im sure you will hear different opinions on using them. personally i would think you should for safety reasons.

    Im using a pretty powerful system aswell (hifonics 1210, l7, large 4 ch amp and 4 polks) I just hooked up two optimas pos to pos, neg to neg and it works great( i also have about a million other electronics and i can let my truck sit with all of them on for hours upon hours and itll start fine)

    Dont use an isolator, they pull current as well. Use a 200 amp relay. Stinger makes them. I cannot remember the schematic, I will dig it up if I can find it.

    You can use batteries without isolation, and normally not have a problem. But to completely avoid the batteries pulling from each other when the vehicle is not running, they need to be the same type AND from the same batch.

    And to all of you that have responded, thanks for the feedback! i appreciate it.

    A Relay and an Isolator are the same thing in this case. You lose a hair of voltage with either.
    An isolator is good for when you want to run your electronics with the vehicle off, so as to not drain the starting battery.

    So Stinger SGP32 200 Amp Battery Isolator is a good one?

    I will be installing a second battery into my Tacoma within a few months. Recently I started researching the different types of isolators that are on the market. I came across an interesting product from Cole Hersee called "Smart Battery Isolator." It's not for everyone, but I plan on using DC electronics for extended periods of time and do not want to put a load on my starting battery. Anyways, I can't vouch for the product as I haven't used it yet, but it does look very interesting.

    I thought I would post this in case somebody else finds it useful.
