Well, the answer isn’t actually so simple. I had a Olight S1A that was made for AA Alkaline and 14500. It had a different mode set for each. I used a 3V cell in it and got weird results. It shouldn’t hurt the driver (maybe) but it doesn’t work right, because the driver tries to be smart and guess which cell is in, and adjust boost/buck accordingly as well as mode sets. I don’t know about your light, but I found the 3V cell to be not worth messing with in the Olight S1A. I generally just kept an Energizer Ultimate Lithium Primary 1.5V AA in it for my EDC, and switched it to a Efest Purple 14500 when I wanted to impress people.
