Alexa camera rapid battery drain on Steadicam rig with Anton Bauer HC batteries

What the thread found

  • Smaller capacity batteries like 90Wh models may not provide sufficient runtime for Alexa on Steadicam compared to larger capacity options like 190Wh or 230Wh batteries.
  • Battery cycle count significantly affects performance, with cells degrading noticeably after 300+ cycles and potentially dropping off sharply in cold conditions.
  • Running camera power directly from a block battery during setup waits or between takes rather than constantly from sled batteries extends overall battery life substantially.
  • Minimum voltage thresholds in Alexa menu settings can be adjusted to optimize power management and may be set conservatively by default.
  • Recelling services can restore old batteries to like-new performance at significantly lower cost than purchasing new batteries.
  • Lower-cost third-party gold-mount batteries from alternative manufacturers can offer comparable runtimes to Anton Bauer at substantially reduced cost and weight.
  • A charger displaying full charge may not indicate cells are completely charged to capacity; genuine full capacity requires verification through camera voltage display or dedicated monitoring.
  • Battery age and storage conditions independently affect performance; batteries stored on trickle chargers maintain capacity better than those left to self-discharge over extended periods.
  • Operating multiple batteries rotated in a rental pool rather than drawing consistently from personal batteries reduces cycle wear on owned equipment.

Depends on

  • Discussion primarily concerns Alexa on Steadicam rig with 24V configuration and two batteries on rack.
  • Some recommendations based on anecdotal experience rather than systematic testing.
  • Specific expected runtime with full accessory payload not definitively established in thread.
  • Cost comparisons and product recommendations reflect 2016 market conditions.
  • Temperature effects on battery performance noted only for cold conditions.
  • Information about recelling applies specifically to batteries past 300+ cycles.
