Have someone ever use just a single 3.7V li-ion cell with Obsidian 3.0

Will it work?
How about loundness comparing with 2 x 3.7V?

I remember asking this question as well and this was the answer as I recall.  " Yes u can power the board with a single 3.7 li-ion cell however u will notice significant difference in sound"  So in other words not as loud. Keep in mind this was on one of the older Obsidian i think it was 2.0. Email Emory or Deep I am sure they could give the best insight. I did fit a 18650 7.4V stick pack into a bellicose but i required small modification, so it would be nice to use just a single 3.7V cell. Curious to see to see the results
