Hi all,

I'm looking for a way to get more battery life out of my GH4 so I can shoot timelapse uninterrupted all day. I see that there are battery grips on Ebay for around $70. Has anyone tried these, and are they any good?

And if not, any other recommendations?

Thanks in advance.

Thanks, that's what I was looking for. Much appreciated.

Where do you plug those in to the GH4?

You insert a mock up of the regular battery. Take a look at the photos on the B&H link. Same idea on the Amazon product, shown in the video.
