Largest studs for car battery
I wanted this circuit breaker as it had the largest studs I could find, available in 200amp and the same side posts made for a very clean install. Three M6x1.0 bolts work great to mount it to the floor in my Mini. It’s very handy when working on the car to just flip the switch instead of having to disconnect the battery. It’s nice and small too. Great stuff.
