  • Pegasus Battery Coupler - Canon

    The Pegasus Battery Coupler for Canon cameras replaces your standard internal battery, so your camera runs from your Pegasus powerbox through the whole night. With 9 models available, from the DR-E5 to the DR-E18, this dummy battery integrates directly with the DSLR output on a Pegasus DSLR Buddy or Pocket Powerbox via its DC 2.1 mm plug. No more swapping batteries in the dark in the middle of a sequence.

    Uninterrupted Power for All-Night Canon Astrophotography

    A dying camera battery is one of the most common frustrations in astrophotography, capable of ruining an entire night's work. The Pegasus Battery Coupler solves this by bypassing the camera's internal battery entirely. It draws stable power from your main rig's power supply, which Pegasus describes as a more stable and consistent power source that lets the camera operate all day and night long.

    Find the Right Pegasus Coupler for Your Canon DSLR or Mirrorless

    Choosing the correct coupler is essential, as each model is shaped to fit a specific range of Canon battery compartments. Match your camera model to the list below to find the compatible Pegasus coupler. This ensures a secure physical and electrical connection inside your camera.

    • DR-E5: Canon EOS Rebel XSi, XS, T1i, EOS 450D, 500D, 1000D, Kiss F, Kiss X2, Kiss X3
    • DR-E6: Canon EOS R, R5, R6, 5DS, 5DS R, 5D Mark II, 5D Mark III, 5D Mark IV, 60D, 60Da, 6D, 70D, 7D, 7D Mark II, 80D

    Safe Power Delivery with a Regulated 8V Input

    This coupler is designed to be powered from the dedicated "DSLR Out" port on a Pegasus DSLR Buddy or Pocket Powerbox. You can also use the adjustable outputs on an Ultimate Powerbox v2 or Pocket Powerbox Advance, but you must configure the output to exactly 8V in the software. Supplying a voltage higher than 8V will cause permanent damage to your camera's electronics.

    A 60-Second Setup for Your Camera's Battery Bay

    Remove the original Canon battery and slide the coupler into the battery compartment. Let the wire pass through the side rubber slot of the battery door and close the lid. Plug the cord into the DSLR Out socket of the DSLR Buddy or Pocket Powerbox. When the camera starts, it may show a message about the power source; select OK and it operates as usual.

  • How do I power the Pegasus Battery Coupler for my Canon R5?

    The Canon R5 uses the DR-E6 model coupler. Connect the coupler's DC 2.1 mm plug to the dedicated DSLR output on a Pegasus Astro powerbox like the Pocket Powerbox. If you use an adjustable output, you must set it to exactly 8V to avoid damaging your camera.

    Which coupler fits my Canon Rebel T7i, and how do I power it safely?

    The Rebel T7i takes the DR-E18. Power it from the DSLR Out of a DSLR Buddy or Pocket Powerbox, or from the adjustable output of an Ultimate Powerbox v2 or Pocket Powerbox Advance set to 8 V only. Pegasus warns that a higher voltage will damage the camera.

    Which Pegasus coupler model do I need for a Canon 60Da?

    The Canon 60Da, a popular model for astrophotography, requires the DR-E6 battery coupler. The same coupler fits the EOS R, R5 and R6, the 5D Mark II, III and IV, the 6D, 7D and 7D Mark II, and other bodies listed above. The original EOS 5D takes the DR-400 instead.

    My Canon camera shows a message on startup with the coupler. What should I do?

    This is normal behavior. Some Canon cameras will detect that a non-standard power source is being used and display a confirmation message. Simply select "OK" on your camera screen, and it will operate as usual.

    Can I power the coupler from something other than a Pegasus powerbox?

    Pegasus documents two ways to power its couplers: the DSLR Out of the DSLR Buddy or Pocket Powerbox, and the adjustable output of an Ultimate Powerbox v2 or Pocket Powerbox Advance set to 8 V. We recommend staying with those, since a wrong voltage damages the camera and those outputs are the ones Pegasus specifies.

    Does the coupler come with its power cable?

    Yes. Every Pegasus battery coupler includes its cable to a DC 2.1 mm plug, ready for the DSLR output of a DSLR Buddy or Pocket Powerbox.
