I broke the positive.

That's the way to do it, cut off the current GOING OUT. I'd think it's too late if you cut off the return line, negative, side.

I have Skinny Water lithiums on my engine, electronics, and trolling motor. All 3 circuits have cut-off switches at the batteries. My Livescope isn’t switched but my Mega Live and Target Lock are switched at the bow.

It does not make any difference.

Pos/neg doesnt matter on a switch, unless you are using your outboard battery which is grounded to the hull. If its a grounded system, you always switch on the pos. If its a closed system, like dedicated livescope battery, it doesnt matter. You ALWAYS fuse/breaker the positive side.
