What reason do you want the dual battery for?

If it is for winching, save ya money and just hook the batteries up together - a voltage sensitive relay is pointless for winching and it only uses one battery.

This is how I did mine, made it myself, cost me nothing but another battery and two terminals.

Fair enough but its a lot easier and cheaper to put a wire from one + to the other +....

Sure the SBI212 will do the job, they are rated for 200 continuous amps with a momentary 600. But they are $340.

A winch motor is pretty common to draw +300amps easy so it'll be fine for a while.
