I have an Olight S1R with the stock cell, which is a [h=1]Olight ORB-163C05 IMR RCR123A / 16340 550mAh 3.7V Protected High-Drain 2.75A Lithium Ion (Li-ion) Button Top Battery.[/h]I was out for a walk tonight with my wife and was using the light intermittently on medium mode. I had the light on for a minute or two at one point, and decided to bust out the Turbo mode. The light went into turbo for about 5 seconds, then stepped back down to medium mode, where I left it for the last 10 minutes of our walk. Ambient temperature is ~12C, so not terribly cold. When I got home, I let the light rest for a bit, measured the voltage at 3.68V, and then warmed it up a bit more against my body. With the light near body temp, I went straight to Turbo, and slowly counted to 30 before I turned the light off. No charging, no removing the battery or disturbing any electrical contacts, just raising the battery temperature 15C or so I would guess, maybe a bit more.
Seems like the light does not like the sort of high drain (600 lumen turbo, not 900 lumen turbo S) when it is "cool". Does this seem reasonable, or do I maybe have a weak sister of a cell? Or maybe this is normal performance for a half drained battery? The cell is about half charged at 3.68V based on past testing I have performed.
