Just got back from a 2 day shoot with the Lilliput and the 9800mAh battery. The monitor was wonderful in the package I pictured a few posts back. I never tried any handheld, so it was totally a studio setup. The Lilliput worked gr8 for focus and review of shots (allthough too much live view can heat up the 7D rather quickly). The battery charged overnight and ran the Lilliput all day long. This is a real winner ya'll.
