Had a brief scare with some unprotected 17670s

[iamerror]

I had just taken the 3x17670 holder off of the charger and was starting to screw on the little cap where the plug is and the metal put a couple of small sparks out. For 1/2 second it gave me a scare. No big deal I guess, what was the reason for the sparking though?

Sure the batteries are in the right way?

Yeah, they are in the right way... they worked when I used them in the flashlight.

Sounds like you bridged positive and negative terminals. Did some insulation wear off around the plug?

I'd say it is a big deal
3x li-co cells is a quite bit of power, don't want that getting out of hand. I dunno what cap you were screwing, but please consider it as if you got off lucky with a warning and do find out the cause.

Maybe I should be more concerned... I was screwing on the gold cap that is on the Fivemega holder. I still don't know what would cause a spark...
