has put together the Switronix PowerBase 70 Battery Pack Kit
to make HD recording more efficient. When you purchase a Canon EOS 5D Mark II or 7D Digital SLR camera, the factory includes a Lithium-ion battery pack. However when using these cameras for HD (High Definition) movie recording, the battery supplied with the camera can often not provide enough power for extended shooting time. This kit, which includes a battery and charger, will help streamline the HD movie recording experience.
