Move the battery upwards and remove it.
Figure 5: ALEXA with BAB-V and V-Mount battery
Note: Not all V-Mount batteries deliver enough power to supply the camera. We
recommend to not use any batteries with a capacity of less than 90 Wh to
prevent damage to the battery and unpredictable camera behaviour. Any
camera-battery combination should be tested prior to use, especially when
accessories are powered through the camera.
8.7 Gold Mount Batteries
Gold mount is the battery mounting system of Anton Bauer batteries.
The batteries transmit information on their remaining capacity to the
camera. ALEXA displays the remaining capacity in percent on the
Homescreen of the camera display. For Gold Mount batteries, the user
does not need to set the battery warning level due to the
communication of camera and battery.
Attaching the battery to the adapter
Place the battery with the three pins into the adapter so that the
pins sit in the corresponding holes of the mount.
Move the battery to the right until you hear a snap.
