As I sit here pondering my speed control on my 1/8th scale I had a light come on in my head. All i need to do to protect my speed control is put an inline fuse on the positive battery leads. There are fuses big enough to do the job. I can put a 125 amp fuse(just an example) in line and never worry about the speed control ever seeing more than 125 amps
esc safety

not sure how that would work, most fuses will take more amps than rated
or take awhile to blow. trip type fuse may work.
but i think you may find it will cause more trouble than its worth just my 2c -

it sounds like a great idea but i am fairly sure it wont work
i cant remember if its because to much resistance is created or voltage spikes but some thing along those lines, what i was trying to think of before was a circuit breaker not a fuse, a fuse quit often has to exceed its rating for a given time before it blows.Comment

Ozzie knows more about sparks than I do.
I do have some practical experience with fuses and breakers from a ametuer point of view. Either of them have quite high resistance which will tax the power source ( your packs ) more than needed.
A fuse is a very slow safety device and even a fast trip CB is too slow for what you are intending. A RCD, which is at the top end of circuit protection is too slow to prevent an esc getting bent over forwards.
A pack will provide near unlimited amps for a very short time, such as a closed/short circuit.
The best way to prevent all of this is as follows.
1. Spec the pack to be 125-150% of what you think you need.
2. Spec the ESC the same.
3. Keep it all dry
This is how I do it and it works well so far.
The exceptions are SAW setups, of which I have done a few. Setups not measured saws.
I hope I was some help.See it....find the photos.....sketch it it....build it........with woodComment
