I took a closer look. When that little strip connected the polarities it heated the plastic and caused it to melt around the connectors. They were fused together, but not touching. It was just the plastic that melted.

Shorted for a split second. I saw the spark, immediately pulled them apart, then realized the plastics had melted and hardened. There were two deans connectors. One on the battery and R1Pro. The other was an inline "plug in" style on the BEC. I wanted it like that so I could take off the bec quickly if I wanted to instead of directly soldering it to the + and - of the ESC.

It didn't fuse the + and - together on the battery. It just fused those first two deans connectors together. Does this make any sense? I can take a picture if I need to. Thanks for the help.
