Battery power requirements and solutions for high-current camera systems with accessories

14 years old. Gear and prices may have changed since.

What the thread found

  • Modern cinema cameras draw between 56 and 90 watts on their own, with the Alexa consuming 83-90 watts, the Red One/MX consuming 75-80 watts, and the Red Epic/Scarlet consuming 60 watts.
  • Accessories such as external monitors (18-28 watts), wireless transmitters (28-36 watts), follow focus systems (28-36 watts), and zoom lens servo drives (4-12 watts) significantly increase total rig power requirements.
  • Complete camera rig configurations can require over 130-148 watts of total power draw when camera and accessories are combined.
  • Battery manufacturers recommend using only 50-60 percent of rated capacity for long-term reliability and constant use, as exceeding this range causes overheating and drastically reduces battery lifespan.
  • Dionic 90 batteries are rated for up to 50 watts maximum continuous draw, and exceeding this rating causes overheating and shortened lifespan.
  • Red brick V-lock batteries rated for 136 watts can power a Red MX camera with monitor and follow focus system when two batteries are used together.
  • PAG 95 watt batteries can reliably power Red One/MX, Red Epic, and Sony F3 cameras with typical accessories.
  • Using rental house batteries or external battery solutions rather than on-board camera batteries can reduce weight on the camera package itself.

Depends on

  • These power consumption figures are from 2012 and may not reflect current camera models.
  • The thread discusses specific battery solutions for particular camera models but does not provide a comprehensive guide for all camera types.
  • Some participants chose to use rental company batteries rather than personal batteries, so their experience may not represent typical independent operator practices.
  • No formal testing data is provided for the battery solutions discussed; these are primarily based on practitioner experience.
