Was this from the kit of parts?

Yes.
We had it wired into our power distribution board, but found out and nothing got damaged.

Is there a way to make sure this warning gets out to all the teams?

Notify FIRST asap. There is a team blast coming out in a couple of days.

How does one "notify FIRST".

Is there a process in place for this?

All done.

We had this all wired up to our Power Distribution Board. Once we plugged this in we heard lots of clicking and quickly unplugged the battery. Luckily our PDB, two Talons, and my RC equipment went undamaged.

Since we only had minimal electronics installed we were quickly able to diagnose the issue and continue testing our drivetrain. :yikes:

Magic Smoke averted...

Everyone should check their KoP components. This should be relatively easy to fix when discovered. Switching the contacts in this connector is pretty simple. I'll make pictures about it upon request. We put one on the new battery and I'm chagrined to realize I didn't check it - - - - yet. The battery beak worked though, so maybe we skated on this one.

From what I remember, the KOP battery cables have an extra crimp in the plastic that makes it more difficult to remove the contacts. I'm afraid that FIRST night have to send out replacements.

Re: WARNING: check polarity
 
First KOP engineers are being notified now.

Re: WARNING: check polarity
 
Are we going to get replacements of these, or is there a way to swap out and modify the plugs?
