Hi all, I was on a shoot today with a Canon EOS C100 MKII, when suddenly it stopped working. It had been working moments before, perfectly fine. We assumed that it had probably overheated and placed it next to a large fan, only for the monitor to say "Please change battery pack" before shutting off again. The battery (Swit) was fully charged. Any idea why this happened? It set us back quite a bit and we still have no idea on what happened.
