Hey guys, so I have become tired of plugging the batteries directly into my VESC, so I have committed to creating an anti spark loop key, but I have a few questions. I made a picture for reference.
-Is there any problems I would encounter if I were to do it this way?
-Do I buy the XT90, or the XT90-S?
-Any links to find some cheap XT90-S or XT90 connectors
No, but it’s advisable to have the connector with the green mark soldered on the board. That’s the one with the resistor. If you lose it it’s game over and hello sparks.
I beg to differ with @RedEagle, since the anti-spark part can fail on rare occasions, it’s better for it to be in the “key” rather than in the board, that way if it ever fails, you can just replace it.
If it’s in the negative side and you get a short without the loop key the negative side could still active as a ground and them the amps flownon the positive.
