Powering a Canon 7D from AB battery sled during handheld filming
16 years old. Gear and prices may have changed since.
What the thread found
- The Canon DR-E6 DC Coupler paired with a Switronix XP-DSLR-C Power Tap enables safe power delivery from AB batteries to a Canon 7D
- A Lemo cage connector to D-Tap cable can route power from AB batteries through a multitap to feed the camera along with focus motors
- IDX makes an AB P-Tap to Canon 5D/7D power supply as an alternative solution
- Direct connection of unregulated 14V from AB batteries to a Canon camera can damage the camera, so voltage regulation through a V-Plate or similar regulated supply is essential
- Using a Canon DC coupler with IDX V-plates and battery provides adequate power while maintaining proper balance on a steadicam rig
- Cable shortening services are available to customize power cables for optimal sled integration
Depends on
- Discussion involves both Canon 5D and 7D models which may have different power requirements
- One user's claim about direct 14V connection causing damage was challenged by another participant who cited voltage regulation solutions
- Specific rental availability mentioned for LA area only
- Cable modification services mentioned but provider details incomplete
