yeah, you can do that, but if you get one of the DPA MPS battery boxes, you can also power them. They also have a model that will condition power, so they can run off phantom power.
I cut off lemo plugs and soldered them into a stereo miniplug (per Schwill's advice/knowledge) - but if they had microdots originally, I would have bought 1 or 2 of the different MPS boxes, depending on the need.
