Dynacore D-MS-NP (7.4V) Sony NP-F to DPM Battery Plate

The D-MS-NP takes a Dynacore DPM-series V-mount battery on one side and presents a Sony NP-F dummy shoe on the other, regulated down to 7.4 V. Anything built around an NP-F - a field monitor, an LED panel, a small recorder - then runs off the larger pack instead of a handful of NP-F cells that need swapping every hour.

It accepts 12 to 16.8 V in, which is the full working range of a 14.8 V V-mount pack from charged to flat, and passes that same voltage through to two D-tap sockets so the plate does not cost you the accessory outputs. It measures 99.5 x 66 x 46 mm and weighs about 0.20 kg.
