I've seen a plugged-in FRC battery spark. I forget whether it was the Anderson or the terminals, but I seem to recall that the area around the Anderson fused (read: welded) to something else before someone could get in there and separate the battery from whatever it was connected to (thankfully, not a robot in that case).


Chris, the thing about using a non-conductive poke stick on the connector is that 1) you only get one place for a spark (the breaker, which in this case is already broken) as opposed to 2 (each side of the Anderson) and 2) your hands are not right there to risk getting zapped.

I don't know about you guys, but I'm not sure I'd want my hands right next to a fully-live FRC battery's current and voltage if I had to unplug it, even with an Anderson connector between my hands and the wires. (By fully-live, I mean current is flowing actively, not current can flow if the connection is made.)
