What the thread found

• Dionic 90 batteries weigh approximately 1.7 pounds, making them lighter than some NiCad alternatives but potentially too light for certain camera setups without additional weight.
• Combining one Dionic battery with one NiCad Proformer battery provides better voltage surge handling for high-demand cameras like the 435, which requires up to 18 amps on startup.
• Dionic lithium-ion batteries alone are not specified to handle the large voltage surges demanded by cameras like the 435, but they perform adequately in the field when paired with NiCad batteries.
• Dionic batteries should be stored at half charge or completely uncharged if not used for more than a couple of weeks, as they degrade when left at full capacity.
• A battery setup of two Dionics and one Proformer can provide multiple days of runtime on 35mm camera rigs with motors and accessories.
• Two stacked Dionic 90 batteries produce approximately 32 volts or higher, which approaches or exceeds the 35-volt safety shutoff threshold on some Arriflex cameras.
• Dionic batteries reduced one operator's total battery case weight by 50 percent while increasing available runtime compared to previous NiCad-only setups.

Depends on

• The one-year warranty offered by the manufacturer for Dionic batteries is shorter than the three-year warranty for NiCad alternatives, reflecting concerns about long-term reliability.
• High-speed operation on cameras like the 435 may present challenges with Dionic batteries used alone.
• Voltage regulation may be necessary when using stacked Dionic 90 batteries with certain camera models due to exceeding safe voltage limits.
• No field testing was completed during the discussion timeframe for some proposed battery combinations.
• The lighter weight of Dionic batteries can affect sled balance when switching between battery types during a shoot.
