Using 14.4V batteries with Arri III cameras
22 years old. Gear and prices may have changed since.
What the thread found
- The Arri III camera should work with 14.4V batteries without fuse issues under normal operating conditions.
- When operating the Arri III above 60 fps with a cinematography electronics base, it is advisable to supply power to the base from a separate battery independent of the camera's power source.
- Arri III cameras are sensitive to overvoltage, so freshly charged batteries should be allowed to settle before use.
- Video tap systems on the Arri III should receive dedicated power from a separate battery rather than drawing from the camera's power supply to avoid grounding problems and image degradation during recording.
Depends on
- Advice specifically applies to Arri III models equipped with a cinematography electronics base.
- The recommendation about separate power for high speed work above 60 fps was not confirmed as standard practice by all respondents.
- The guidance assumes standard charging practices and does not specify how long newly charged batteries should settle.
