Frequently Asked Questions
The Ursa Power kit v-mount plate is compatible with every camera in the Blackmagic Ursa line, including the original Ursa, Ursa Mini 4k, Ursa Mini 4.6k, Ursa Mini Pro, Ursa Mini Pro G2 and Ursa Broadcast cameras. The v-mount plate connects via the camera’s internal power port, hiding the wired connection behind the v mount plate.
The 150Wh v mount battery that comes with the Ursa Kit is compatible with all standard v mount systems.
Installation requires only a phillips screwdriver and takes just three steps. Four screws are removed from the Ursa camera, the v mount plate’s power connection is plugged into the back of the camera and the v mount plate is secured to the camera with four screws.
More detailed instructions are included with the Ursa Power Kit’s manual and, if you need any extra help, just contact us and include your phone number. We’ll get back to you right away and we’ll be happy to call you and walk you through the installation.
Yes, any standard v mount battery will fit the Ursa Power v mount plate and will be compatible with your Ursa or Ursa Mini.
Ursa and Ursa Mini cameras use just two contacts to power the camera, a positive connection and a ground. All other connections available on the camera and included with other v mount plates are not power connections but enable communication between the battery and the camera. This feature, which makes the battery’s remaining charge level appear on the Ursa or Ursa Mini display, is available only with higher end batteries. Juicebox batteries do not have this feature but, instead, utilize a built-in LED indicator to display the charge level of the battery.
The charge level of Juicebox v mount batteries can also be read through the voltage input displayed on the camera. At maximum charge, the Juicebox battery puts out about 16.8 volts. At about 13 volts, the Juicebox is in need of charging.
Juicebox’s v-mount batteries are compatible with all standard v-mount systems, including those offered by all major camera and camera accessory manufacturers. Our v-mount batteries are designed to fit all standard v-mount plates and the voltage output is compatible with all devices that accept v-mount batteries.
The 95Wh v-mount battery is designed to be small and lightweight while still delivering enough voltage and amperage for v-mount devices. The JBVB-95 is capable of sustaining up to 10 amps of power, meaning that these batteries, though not as high capacity (long lasting) as their 150Wh counterparts, are capable of powering the same v-mount devices. They are more-than-capable of powering a single camera and monitor simultaneously and are perfect for shoulder mount rigs, flying on gimbals and any other use where portability and weight are a factor.
If your camera accepts standard v-mount batteries or has a v-mount battery plate installed, Juicebox’s v-mount batteries are compatible with your camera, both in voltage output and in the fit of our v-mount battery to your v-mount plate. Further, Juicebox batteries have extremely reliable, built-in overcharge and over discharge protection, keeping your camera and other devices safe from power surges or short circuits.
Juicebox v-mount batteries are compatible with many non-v-mount camera systems, as well, including Blackmagic Cinema Cameras and Blackmagic Production Cameras. Check your camera’s documentation; if it can accept inputs of 14.8 volts (i.e. the Blackmagic Pocket Cinema Camera 4K’s requirement of 12-20 volts), it is compatible with our v-mount batteries. In many cases, a power adapter cable is necessary, typically a d-tap-to-DC adapter. Please see your camera’s documentation on power input to find requirements for the necessary cable/adapter.
The USB port on the JBVB-01 battery can be powered on by pressing the LED indicator button on the side of the battery. This button turns on the USB port, which will remain on as long as a device connected to the USB port is drawing power from the Juicebox battery.
JBVB-01 v-mount batteries utilize LG brand, 2600 mAh, li-ion cells. These cells have an extremely good reputation among power supply manufacturers and we have found these to be the best quality li-ion cells available, with no memory effect and extremely low failure rates.
Juicebox v-mount batteries have a built-in LED indicator that allows the user to see the current charge level of the battery. The voltage level of our v-mount batteries will also display in cameras with this display capability, such as Sony cinema cameras, Blackmagic Ursa and Ursa Mini, RED and ARRI cameras. Juicebox v-mount batteries do not, however, communicate charge level percentages to cameras or chargers.
Our v-mount batteries have a standard d-tap input/output and a 5V, 2.1 amp USB output. The d-tap output is an industry standard connection and outputs the same voltage and amperes as the batteries’ v-mount connection (14.8V, 10.4 amps). The d-tap port is also an input and can be used to charge the v-mount battery with the included Juicebox charger.
While your Juicebox v-mount battery is charging, the Juicebox charger will glow red. The charger’s LED light will glow green when your Juicebox v-mount battery is fully charged.
Also, Juicebox v-mount batteries have a built-in LED indicator that allows the user to see the current charge level of the battery. Just press the button on the side of the battery to see an LED display of the battery’s current charge level.
Another indication of the battery’s charge level is the voltage output, displayed on many camera models. When the Juicebox’s output dips below 14 volts, the charge is low and the battery should be swapped.
Juicebox v-mount batteries can be charged with any v-mount charger that does not require a digital capacity readout from the battery. Compatible dual chargers include Dracast, Rolux, Indipro, Soonwell and Neewer chargers. Some higher end chargers, including IDX and Blueshape, need to communicate with the battery before initiating charge. Juicebox batteries are not compatible with these chargers in this regard. To verify whether or not a specific v-mount charger is compatible with Juicebox batteries, check the charger’s manual to see if digital “communication” with the battery is required for charging.
Juicebox v-mount batteries are designed with overcharge and over-discharge protection to protect the batteries and connected devices. If the power draw on the battery exceeds 10.4 amps, the battery will shut off. To reset and power the battery back on, connect the battery to the battery charger. If the Juicebox v-mount battery shuts off during use, it’s likely that the connected devices are drawing too much power from the battery.
If your camera rig requires several devices to be powered simultaneously, exceeding the JBVB-01’s 10.4 amp power draw, you may need to use more than one v-mount battery to power your camera rig.
If your Juicebox v-mount battery is shutting off during use and you believe it is not a result of a power overload, please contact us for further assistance.
