em5 battery grip
the controls: the buttons and dials on the lower part of the grip.
Which battery you use first is controlled by the camera.
What bothered me until I got used to it was the camera showing 'battery low' even though it still had a full charge on the one in the camera... Don't worry, you still have time, and you can swap out batteries in the grip w/o powering down the camera (as long as the one in the camera has juice)-- hide signature --

of light and shadow.
I live where the two play together,
I thrive on the conflict"
That's good to know thanks so much Art_P.
Some things I can't find in the manuals.
Getting to like this camera more and more.
