The DV-7QS is a direct power solution for Convergent Designs Odyssey 7Q providing power from dual Mini DV NPF (L-Series) batteries DV-F970 /
DV-F980 fitted to a plate which fits direct to the rear of the monitor/recorder.

The Mini DV batteries are wired in series giving you combined power of about 100 watts which provides an approximate run time of around 6 hours or so whilst using the Odyssey for monitoring and recording.
