Battery weight considerations for ProVid camera rigs and dynamic balance
21 years old. Gear and prices may have changed since.
What the thread found
- ProVid camera rigs achieve proper dynamic balance when batteries have sufficient weight, typically around 2 kg, making lighter lithium batteries potentially problematic for balance
- Heavier camera setups require longer posts to maintain balance if lightweight batteries are used
- Brick-type batteries provide better weight characteristics for dynamic balance than lighter lithium options
- NiCad batteries such as PAG C50 or PP20 models offer a middle ground between capacity and weight for balance purposes
- Individual batteries can be matched to identical weights by adding ballast material, allowing seamless battery swaps without requiring re-balancing
Depends on
- The discussion specifically addresses ProVid rigs and may not apply to other camera systems
- Swit lithium batteries showed compatibility issues with certain other equipment models, though reportedly not with ProVid
- The claim about battery weight affecting balance is presented as practical experience rather than tested engineering specifications
- Only NiCad and brick-type batteries are discussed; other battery chemistries and designs are not evaluated
