Magic smoke came from my new xt90 anti spark loop key.
This is my first time using this so I prob did it wrong lol I plugged it in and my motors were moving very slow and then the male “key” with the resistor started smoking.
What did I do wrong
Do I have to have the live wire at a particular end of this ? Or can it go on either end
about the loop key: I know quite well why my loop exploded and yours worked: my loop was too large! most of you directly bridge the 2 soldering joints of the XT90s plug and then attached something to pull the plug out again. I thought I just use a cable and wind it in a slightly larger loop, so that I can use it to pull the plug out at the same time. the problem is, that the inductance of a single wire loop is increasing with loopsize (~ radius*log(radius)), so the inductance of my loop key was much larger than that of most others.
It might be that I need to put the power on the other side but I have no more to test it out. They cost 12 dollars for a pair lol I’ll have to order more.
I went ahead and made me a temp regular xt90 key so I can use the board it works fine
Shouldnt really matter what side… i have a sneaking suspicion that these XT90s are not up to task. They use only very small smd resistors. I don’t think high voltage e skateboards were in mind when they were designed.
I have no proof of this… just a theory.
