Installed the breaker this evening. The car started fine without tripping it. Then again, it's a hot summer-ish evening and the car had only been off for 5 hours. Might be different on an ice cold morning in the dead of winter with a car that hasn't been run in 2 days. We'll see when I get there in the winter
I also went ahead and prewired a little harness for my trickle charger in case I need/decide to use it. The breaker is mounted to the top of the battery box with superglue (I know, how ghetto of me).
But anyways, yes, the Lightning Audio LCB-200 seems to do the trick, providing short-circuit protection as well as a convenient way to kill the battery power when working on the car.
