Safety shutoff.

[mr_fons]

What are your thoughts of using an external power shut off on our electric boats,
something like in this picture, or is it going to be another point of resistance and power loss?
I was thinking about safety of boat retrieval and the possible bump of throttle or accidental
powering off of the transmitter.

Submitted for discussion.

I believe they are required in Europe. If done correctly it should not hinder performance.

I don't like them! There are a pain to configure especially in a 2P boat. They add extra wire. They add resistance and another failure point. What you have pictured might work for a 75A setup, but try that on a 350A setup with twin batteries.
