The CoreSWX Short Form Factor Hotswap Shark-Fin Mount Battery Mount mounts on you camera's V-mount plate and enables simultaneous mounting of two V-mount batteries. The batteries are mounted in parallel, which allows the two batteries to act as one larger battery with increased capacity while maintaining the voltage. As one battery becomes exhausted, you can remove it and swap it for a charged battery without having to power down your camera.

The Shark-Fin also incorporates four D-Taps for accessory power. These D-Taps are unregulated, and will deliver from 11 to 17 VDC, which will power most cinema accessories.

Hot Swap Battery Adapter    Mounts on V-Mount Battery Plate    Four Unregulated D-Tap Outputs

The batteries mount in parallel which allows the voltage of each to remain essentially unaffected by adding or removing a battery to the Shark-Fin. However, it is recommended that you use matching capacity batteries in a similar charge state.

For example if a fully charged battery (16.8V) and a fully depleted battery (11V) are used together, the circuitry will divert the load to the fully charged battery and your camera will see the higher voltage, not an average. So there is no need to worry about accidentally hot swapping a depleted battery on as long as the existing battery has enough power to maintain camera power.

The Shark-Fin will draw from both batteries as long as they are in the acceptable voltage range. Once one battery drops below that range (11 VDC) the Shark-Fin will stop drawing from it.

Core SWX batteries also have protection circuitry to prevent being charged from one another.

Related Questions and Answers

Q: 1. Do both of the d-tap ports stay hot when you swap a battery? Or are they tied directly to one of the battery plates?

A: Yes they do.

Q: 2. What does unregulated power outputs mean on this item and is there a risk they could short circuit my camera or connected accessories?

A: The Sony FS7 can work safely with V mount and gold mount batteries which are nominally rated for 14.4VDC. Nominally in reality means the voltage varies from 14.4VDC. However, no worries on this plate for the voltage from the battery to the camera is regulated to a 11VDC to 17 VDC range and the camera self regulates to these same voltage numbers. Very commonly like here however, the D taps voltage is straight out whatever the battery is outputting with no regulation. If you use it on a light, there is no danger, the light will just dim and go out. If the device is complicated computer circuitry, I would not hook it up unless it had its own internal voltage regulation.

Q: 3. Does this unit actually power the camera and how is that connection made?

A: Yes it powers the camera through a small cable that connects to the DC in port in the back of the camera. You can still have a small sony battery in the camera so it actually becomes hot swappable :)

Q: 4. Does the battery plate each come with just 1 d-tap or 2?

A: The battery plates come with 1 D-Tap connection on them.

Q: 5. Can this work with the Canon C400?

A: No, the Core SWX V-Mount Plate Set for Atomos Sumo is not compatible with the Canon EOS C400 6K Full-Frame Digital Cinema Camera (Canon RF), BH #CAC400RF.

Q: 6. Will this install on the Bright Tangerine top plate for the FX6?

A: The Core SWX Articulating Gold Mount Battery Plate for Sony PXW-FX6 is designed to attach directly to the FX6 when installed. Once the plate is mounted onto the camera, the battery plate position can be adjusted by tilting the hinge. The assembly closely matches the rear profile of the camera to allow it to efficiently fit in a camera case.

Q: 7. Do these fit cameras and accessories for mini v-lock?

A: Yes, the Core SWX Hypercore G3 99V 99Wh Lithium-Ion Battery (V-Mount) would also work with Micro Vmount adapters.

Q: 8. can this battery be charged via the d-tap?

A: Yes, the Core SWX Nano XL 178Wh Mini Li-Ion Battery (Gold Mount) does allow D-Tap charging. Charger idea: Core SWX 1.5A Single-Position D-Tap Charger BH #COPB70C15US • MFR #PB70C15US

Q: 9. Will the Core SWX XL battery charge on a older Anton Bauer charger?

A: Older Anton Bauer chargers like the Anton/Bauer TWIN Simultaneous Charger for Gold Mount Batteries can be an issue with third-party batteries like the Core SWX Nano XL 178Wh Mini Li-Ion Battery (Gold Mount) because of the chip communication the charger has before charging. A newer charger like the Anton/Bauer GM2 Dual-Bay Charger with 4-Pin XLR Output (Gold Mount) is much more forgiving with third-party batteries. See the link below: https://bhpho.to/3sxixuo

Q: 10. Does this battery work with the Core SWX FLEET Quantum 4-Position Charger with Touchscreen Color LCD v mount charger ?

A: Yes, the Core SWX FLEET Quantum 4-Position Charger can charge the Core SWX Nano XL battery.
