BMPCC4k Keeps shutting down with included battery

My BMPCC4k keps shutting down with the included battery even when charged.
I tried other batteries as well. I don't have original Canon to try at the moment.
It seams to happen when I use PANA100-300mm with OIS enabled.
Anybody else experience that?

YUP.

Care to elaborate?

Your power requirements seem to be exceeding the ability of the BM Battery, when the battery level drops to a certain level, the camera shuts down. Try an external, larger capacity battery, or at least an Canon OEM LP-E6 Battery.
