Grip is good, but not all

I've bought because I wanted to have a reasonable handle, the battery expansion seemed to make sense to the further release and adjustment knobs in the part: all this had me convinced the rather lavish sum to invest.
After the part had arrived I wondered myself first that no battery is incl. Exactly when you reread one recognizes this, but the impression when reading is another. By the way, at Amazon, which will ship the as hazardous because Lik battery should be in there. People you relaxed, there is none there. Kostst Olympus again around 50th
Then turn built the handle, which is good: ergonomic grip, trigger at the right place. However, it no longer comes to the battery compartment of the camera. It really is not so important, after all, the battery compartment has a charging socket, I thought.
In fact, you can connect the battery compartment probably not invite (habs not tried, but after research), for a suitable power supply should you still spend 90. In order to photograph the cable? To load one has to refer to both batteries (for the so unscrew the handle on the camera).
That means for me: In the end brings me only the handle ergonomics. More battery power I have over the extra battery I lay me but easier in the pocket and change it in the camera itself. I'll send the part directly back.
My solution is: Instead of HLD-6 Power adapter + battery for> 350 rather have a "Just-handle" + Battery for max 100
