  • Pegasus Battery Coupler - Nikon

    The Pegasus Battery Coupler for Nikon replaces your camera's standard battery, and runs it from your Pegasus powerbox through a cable with a DC 2.1 mm plug. This dummy battery system eliminates the need for battery swaps on compatible cameras like the D5300 (EP-5A) or D750 (EP-5B), so a dead battery no longer cuts a sequence short.

    8V of Stable, All-Night Power for Nikon Astrophotography

    For any DSLR astrophotographer, the greatest enemy of a long imaging sequence is the limited life of a standard camera battery. Swapping batteries in the dark risks bumping the telescope, losing focus, and interrupting a carefully planned session. The Pegasus Battery Coupler solves this by completely replacing the internal battery with a reliable, external power source.

    Pegasus describes it as a more stable and consistent power source that lets the camera operate all day and night long, and you never have to touch the camera between subs.

    Choosing Your Coupler: EP-5A vs. EP-5B Compatibility

    Selecting the correct model is critical, as each coupler is designed for a specific Nikon battery type. Pegasus offers two versions to cover a wide range of popular Nikon cameras used for astrophotography.

    • EP-5A for EN-EL14 Batteries: This model is compatible with cameras such as the Nikon D3100, D3200, D3300, D3400, D3500, D5100, D5200, D5300, D5500, and Df, as well as Coolpix P7000, P7100, P7700, and P7800 models.
    • EP-5B for EN-EL15 Batteries: This model fits higher-end bodies including the Nikon D600, D610, D750, D800, D800E, D810, D7000, D7100, and the Nikon 1 V1.

    Safe Integration with Pegasus Powerboxes at 8V

    This coupler is designed to integrate directly into the Pegasus Astro ecosystem. The DC 2.1 mm plug connects to the dedicated DSLR output on a DSLR Buddy or Pocket Powerbox. That is the output Pegasus designed its couplers for.

    If you are using a Pegasus Ultimate Powerbox v2 or Pocket Powerbox Advance, you must use one of the adjustable outputs and manually set the voltage to 8V. This is a critical safety step. Supplying a voltage higher than 8V will permanently damage your camera's electronics. Always verify the output voltage in the control software before connecting the camera.

    Simple Installation: Connecting the DC 2.1 mm Plug

    Installing the coupler takes only a moment. First, remove the original Nikon battery from your camera. Slide the Pegasus Battery Coupler into the battery compartment.

    Let the wire pass through the side rubber slot of the battery door, then close the lid. Plug the DC 2.1 mm connector into the DSLR Out of your DSLR Buddy or Pocket Powerbox, or into an adjustable output already set to 8 V. When you turn the camera on, it may display a message; simply select "OK" to proceed, and the camera will operate as normal.

  • What is the purpose of the Pegasus Battery Coupler for my Nikon D5500?

    The Pegasus Battery Coupler acts as a "dummy battery," replacing your standard Nikon EN-EL14 battery. It allows you to power your D5500 from a larger, external power source like a Pocket Powerbox for an entire night, eliminating the need to swap batteries and risk disturbing your imaging setup.

    Which Pegasus Coupler do I need for my Nikon D810?

    For the Nikon D810, you need the Pegasus EP-5B Coupler. This model is designed as a replacement for the Nikon EN-EL15 battery, which is used in the D810 and other models like the D750, D610, and D7100.

    How do I power the Pegasus Nikon Battery Coupler with my Ultimate Powerbox v2?

    You must use one of the adjustable voltage outputs on the Ultimate Powerbox v2. In the Pegasus software, set that output to 8 V before you plug in the coupler. Using a higher voltage will damage your camera. Do not use the 12V outputs.

    Will using the Pegasus Battery Coupler damage my Nikon camera?

    Not when it is powered the way Pegasus specifies: from the DSLR Out of a DSLR Buddy or Pocket Powerbox, or from an adjustable output set to 8 V. Pegasus warns that a higher voltage will damage the camera, so never plug it into a 12V output.

    My Nikon D3400 shows a message on screen after installing the Pegasus Coupler. What should I do?

    This can happen when the camera starts on a coupler. Pegasus says to select OK, and the camera operates as usual.

    Which coupler fits a Nikon Df?

    The Df uses the EN-EL14 battery, so it takes the EP-5A coupler (PEG-COUPL-ENEL14).
