THE DEF GUIDE
Hawk-Woods: In recent years, one of the main focuses has been to make everything smaller, lighter and more portable. Whether it is testing out different types of cells or configuring the internals, making batteries smaller without losing runtime or power has been sought-after by the end user. NXTGENbps: Usage and monitoring data will become essential for managing and specifying power needs. In turn, this will drive greater efficiency in power usage and transform the ways of working within the industry. Anton-Bauer: Sodium-based batteries will begin to dominate the market. Who wouldn’t want a more environmentally friendly, longer-lasting battery with higher continuous output? Def: What are some of the biggest customer considerations when it comes to buying batteries for filmmaking? Bebob: Customers should aim for high quality and durability to secure their investments. Product and transport safety is another issue – watch out for the appropriate certifications! We will
has many similarities with lithium- iron sulphate, but it also has many advantages, including very high C rates, wide operating temperature ranges, longer cycle life and safety. Sodium is much more environmentally friendly than lithium and can be completely recycled. While the energy capacity of sodium is a bit less than lithium- iron sulphate at this moment, the advancements in this area are rapid. NXTGENbps: Filmmakers should keep an eye on emerging technologies, which include sodium batteries, hydrogen power solutions and ongoing developments in lithium technology to enhance energy density. Additionally, expect to see batteries with built-in intelligence for optimised power usage and real-time data reporting in order to calculate CO2 offsets. Def: Where would you say the future of battery technology within filmmaking is heading?
also see a rising interest in sustainable solutions, such as re-cellable batteries. Many people are also looking for the cheapest solutions. This is understandable, but they should be aware that high quality, high safety and real sustainability aren’t cheap. Anton-Bauer: You would hope it is quality, life cycle, durability and safety features – unfortunately, it is normally price. Return on investment should always be a key consideration. In the long run, buying a quality battery is good for both the wallet and the environment. NXTGENbps: Capacity stands out as a significant concern. Often, customers over-specify their battery requirements due to their familiarity with diesel power. Educating customers about the nuances and differences between diesel and battery capacity is crucial. Portability is also essential for crews who frequently move batteries around sets, sometimes on uneven ground, in pursuit of capturing shots at various locations. Def: Are there any common pain points that filmmakers consistently encounter with existing battery technologies?
