150Wh V-mount Battery and Charger
Below are some common questions and answers regarding the JBVB-01:Are Juicebox v-mount batteries compatible with my v-mount device?
The JBVB-01 is capable of sustaining 10 amps of power draw at up to 16.8 volts, meaning that it is capable of powering multiple devices with a single battery.
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 Cinema Camera’s requirement of 12-30 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.
Why did my JBVB-01 v-mount battery shut off during use? How do I power it back on?
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, you may need to use more-than-one 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, contact us at email@example.com for further assistance.
How do I power on the USB port on my JBVB-01 battery?
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.
What type of battery cells are used in the JBVB-01 v-mount batteries?
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.
Will Juicebox v-mount batteries communicate with my camera?
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.
What power inputs and outputs are available on the JBVB-01 v-mount batteries?
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.
How do I know when the battery is fully charged? And, how do I know when the charge is getting low?
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.
Can I charge Juicebox v-mount batteries with a different v-mount charger?
Yes, Juicebox v-mount batteries can be charged using any v-mount charger intended for li-ion batteries. Check your charger’s documentation to see if it is designed for use with li-ion batteries. Nearly all recent model v-mount chargers are designed for charging li-ion cells.
