Battery kill switch

I was thinking about battery kill switch and was wondering it one of those would do the job and be safe :

That should do just fine - watch your amperage and use properly sized wires. We have a dozen or so on the boat for isolating loads.

Don't open it with the alternator running - you'll most likely blow the alternator!

try mounting one of these, my company has them on all of their trucks and never have a problem

I put one of these on mine 2 years ago, the gold with a remote. works great.

That's what I was concerned with, what kind of amperage I should aim for.

That one is rated at 150 Amps - just how much will you run through it depends;
On the alternator size; the regulator and its charging scheme; the depth of discharge of the battery when charging; temperature; etc.


Blue Sea has made those for a while. They have a calculator that might help:

I'd use 3-5% voltage drop and check your wire for its thermal rating.
A little easier chart can be found Google ABYC Wiring Standards. Heaps of helpful ideas.

Be safe!

I'm using the switch that mounts directly at the battery terminal, most vendors and local parts stores sell these... it's been about 4 years, so far so good... no problems....

I have installed this, very handy and no issues.....using a wooden block to adapt the switch. I operate the switch from my driving position.
