The driver circuits aren't that efficient though, I'd estimate the nixies take about 10W and the board loses another 15W. If the edges were made wider it would be possible to fit enough mh cells in for maybe 2 hours or longer using Li. As it stands though it can be fed from an external 12v battery, the terminals are marked 'LT accumulator' though it's not very easy to see in the videos.
