Currently the pucks are being directly soldered to the motes within them. While this is a sufficient solution for investigative and research purposes, it is desirable to have the puck removable for field serviceability. One potential solution from Molex is shown here. The 3-position connector is very slim and fits beneath the mote. More room could be added to the molding in the future to accommodate the connector further or to provide for a friction fit for the connector to hold it in place.

Note: This connector setup is not polarized and could be installed backward. With more room, a locking, polarized connector would be desirable. I believe this is possible within the same family of Molex connectors. For now, our space constraint precludes this.
