Well I am hoping someone can straighten out my thought pattern here. This would be what I would foresee as a second battery setup. It would allow me to put everything under the seat on the 700 and only have the ignition activated fuse panel for attaching accessories located in the front. That way the front wouldn't be so full of wires and be so much cleaner. I already have my wench installed and feel like I can find a good ground under the front hood for fuse panel.

I can with 99% certainty say... the stinger relay is just a relay. Once the relay sees 12v, its closing and the batteries are paralleled until that 12v reference is gone. I’m assuming what stinger means by “isolator” is that you can isolate the two batteries from each other by a switch. If you don’t mind manually switching, then ya it’s fine. I just know how I am... in a situation where you’re stuck or trying to get somebody else out, the last thing I want to do is be worried about switching between batteries. It’s not wrong either way, it’s all just how you want it to be set up.I am waiting for a reply back from Stinger as we speak but a guy down the street from me has a stinger in the same configuration that I show and he also told me it is an isolator but it is indeed a relay isolator just as Stinger describes it in their naming of it. Also as described in earlier threads the relay isolator appears to be a better device to use in a dual battery situation. I am waiting for the reply from Stinger to see if it actually does as in the description of a relay isolator and will automatically use the power from the second battery to add power to the main battery if it does not have enough power to start the engine. I will have to also ask if it will try and charge both batteries at once. That is a good question. I know it will isolate batteries but haven't found how they charge.
