What the thread found

• Dionic batteries achieved an extended runtime on a Panavision Millenium XL camera rig, powering three days of steadicam work totaling eleven 400-foot film magazines without requiring a battery change.
• Dionic batteries weigh approximately 1.7 pounds compared to Hytron 50 batteries at 1.88 pounds, though they take roughly 2 hours 45 minutes to charge from fully depleted.
• Dionic batteries are rated for approximately 300 charge cycles according to manufacturer specifications.
• On film productions, battery changes can typically occur during film magazine reloads, reducing the need for long-running battery capacity compared to video work.
• Proformer batteries charge in approximately 45 minutes and weigh about 1.87 pounds, but the product line has been discontinued by the manufacturer.
• Proformer batteries do not fit the original PRO 2 battery cage without modification, specifically requiring lowering the adapter plate and redesigning the recorder mount.
• A voltage monitoring solution can be constructed by combining a simple automotive LCD battery meter with a PowerTap connector, costing approximately fifty dollars total.
• Anton Bauer warranty coverage may be denied if the company determines battery failure resulted from high-draw applications, though HD camera use draws more current than film camera use.

Depends on

• The account of extended Dionic runtime is secondhand rather than direct observation.
• Warranty denial experiences with high-draw applications are reported but create conflicting information about actual coverage policies.
• The performance comparison focuses primarily on one specific production setup and may not generalize across all shooting conditions.
• Dionic battery testing for long-term cycling durability was limited at the time of this discussion.
