It takes about 7 AA batteries.
How we worked it out
A small camera drone battery holds about 19 Wh, and one AA holds about 3 Wh. Alkaline AA batteries, about 3 Wh each, and no energy lost on the way. Real life adds a little friction and waste, so treat the number as a solid ballpark rather than a lab result. The constants behind every experiment are on the science page.

This was one of the five experiments in It Took #17. In the game you guess first, then the experiment plays out with your number: too few and it fails, too many and it overshoots.
