The BG-C11 Battery Grip from Precision is designed specifically for the Canon EOS Rebel SL1 DSLR. It holds one or two LP-E12 batteries, and therefore can effectively double the camera's normal shooting time.
The design of the battery grip offers a comfortable and secure way in which to hold your DSLR in the vertical position. The BG-C11 comes with an alternate shutter release button to facilitate shooting when held vertically. An on/off button allows you to disengage the grip's shutter button to prevent accidental firing.
