The system's simplicity ensures that even under pressure, crew members can execute battery changes confidently and quickly.
Can I use different battery plate types on the same monitor?
Yes, this is precisely the advantage of Marshall's Quick Change system. The base plate mounted on your monitor accepts multiple battery plate types, including assemblies for Canon BP-970G, JVC BN-V438U, Panasonic CGA-D54, Panasonic VW-VBG6, and Sony NP-F970 batteries in addition to this Sony NP-QM91 assembly.
