This is an original Canon BG-E2 battery grip. It will come with an OEM BP-511 battery for 20D/30D/40D/50D, which is holding charge well; so you can fill the battery grip with 2 batteries for a full boost power. The battery grip has normal wearing, and a scratch near the shutter button, which is shown clearly in the zoom-in photo. Fully functional with no hidden problem. No box. Asking only for $70.
