A three-battery system provides better power delivery and runtime than two-battery setups for film cameras.
Dionic 90 batteries can run a 435 camera up to 48 frames per second, but adding a nickel-cadmium battery like a Proformer enables higher frame rates up to 150 fps.
Hytron batteries are viable for film cameras but decline in performance after one to two years of use, especially for high-speed operation.
Different battery chemistries can be safely combined in series to meet the power demands of high-draw cameras, but should never be connected in parallel.
Nickel-cadmium batteries are necessary for film camera operation while lithium-ion is better suited for digital cameras.
Dionic 90 batteries can legally be carried as hand luggage on aircraft under current regulations, whereas older battery types may face fewer travel restrictions.
Two Dionic 90 batteries alone are insufficient to power a 435 camera reliably.
A system designed for the power requirements of a 435 camera will reliably run any other film camera model.

The power performance of lithium-ion and nickel-cadmium batteries degrades significantly with age.
Lithium-ion batteries cannot be checked as baggage on aircraft, which may limit their use for traveling crews.
Hytron 50 batteries showed capability for 120 fps operation on a 435, but this claim was not universally confirmed across different usage scenarios.
One participant used three Hytron 50 batteries successfully but acknowledged this outcome might be dependent on battery age.
The Proformer battery model discussed is no longer in production.
There is conflicting information about whether newer high-draw lithium-ion options like the Tiffen Powercube are optimal choices given compatibility issues with existing equipment.
