Good Plate.

This is a good battery plate. Works fairly well behind a Bmpcc4k. Love SmallRig quality. It would be nice if it could be turned sideways on the rod clamp, but there’s no space for screws with all the ports. Still works great though.

Noisy but works

This is a little large for my Bebop v-mount batteries so I'd only recommend this if you have larger style batteries. Also when it's switched on you WILL NOTICE electronic noises coming from the plate. This noise is then in addition to the noise that comes from the D-tap to FX6 power cable so if you record sound with on camera mics I wouldn't recommend this at all.

Does this plate have parasitic draw when turned off?
Asked by: brennish
No, the SmallRig 3203B Advanced V-Mount Battery Mount Plate does not exhibit parasitic draw when turned off; it isolates power from the battery to connected devices when the switch is off.

Does anybody know why this device would only flash green with a Battery or USB-C hooked to it? No power delivery out to devices.
Asked by: Randy
Mine also flashes green when battery connected, and won’t let it be used. Flashing is supposed to indicate overheating, but mine is cold. So I think it’s either a defective unit or incompatible battery.

Can i use this on Sony PXW-FS7M2?
Asked by: Alex
Yes, the SmallRig V-Mount Battery Adapter Plate with Dual 15 mm Rod Clamp can be used with many cameras. Moreover, you would need a 15 mm rod baseplate solution as well to mount the plate. You would need a D-TAP cable to power the camera from the battery mount.
