[NSRCA-discussion] arm/disarm 10S

[Dave Lockhart]

There is no harm to the batteries or ESC from the spark.  There can be some erosion on the connectors from the arcing.  Most connectors suffer the erosion on the ends of the connectors, and not on the  mating surfaces….in which case, the erosion really doesn’t cause a problem.

 

Anti-spark arming circuits that are in the primary power delivery pathway are a potential point of failure.  Much better to use a secondary parallel pathway to absorb the spark and charge the caps, and then plug in the primary leads, and then disconnect the secondary ones.

Regarding an arming system, I don't fly 10S but from what I understand when you are up around 8-10S it is a bad idea to connect the batteries directly.  The caps on the front-end of the ESC can instantly draw a huge surge of current for a short time.  The arming systems for that sized pack usually have a button with a resister in series.  You hit the button for a few seconds and that lets the caps charge up slowly.  Then you plug the full-current connector in.
