مقارنة الأداء لبطاريات ليثيوم - إيون من بطاريات كوي باور، التي تبلغ Tiffen، مقابل تكنولوجيات البطاريات البديلة لمعدات كاميرا عالية المستوى
مضى على هذا 20 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- سلّمت بطاريات كبطاريات الطاقة على نحو أفضل بكثير من تكنولوجيات البطاريات المتنافسة عندما تم اختبارها لتزود جهاز تصوير جينيسيس بأجهزة تسجيل سطح وأجهزة تحويل أسفل، مما حقق 45 دقيقة ببطارية واحدة و 75 دقيقة ببطارية واحدة مع بطاريتين في الوقت نفسه تشغيل جهاز رصد إضافي
- تزن بطاريات كبطاريات الطاقة حوالي IDX بطاريات في 750 غراماً على الرغم من الأداء العالي وكثافة الطاقة
- Power Cubes utilize lithium-ion chemistry and charge to 80 percent capacity in approximately 2 hours and fully charge in 2.5 to 3 hours using an IDX VL 4-S charger
- A practical operational setup requires a minimum of three to four battery sets with two chargers to maintain continuous shooting, though six batteries and two chargers provide comfortable operating margins for most work
- Switching from established battery mount systems like Anton Bauer to the IDX V-mount system required for Power Cubes involves substantial additional costs for new mounts, chargers, and adapters that can exceed $8000 for a complete conversion
- Dionics 90 batteries with 10-amp draw limitations showed acceptable performance over extended use on Genesis equipment but demonstrated lower energy density compared to Power Cubes
- Hytron batteries appeared to provide less than half the runtime of Dionics batteries when powering a Genesis camera body without deck components
- No Anton Bauer mount version of Power Cube batteries was planned by the manufacturer, limiting adoption among users with existing Anton Bauer equipped rigs
يعتمد على
- The initial performance testing was described as unscientific in methodology
- Battery cycle lifespan data was not available at the time of testing
- Runtime measurements varied based on specific equipment configurations and were not conducted with identical loads across all battery types
- The discussion includes opinions about cost justification that are subjective and dependent on individual financial circumstances and existing equipment investments
- Some performance reports regarding Dionics and Hytrons were based on informal observation rather than controlled testing
