Tech question about Fenix PD32 and new S2 light

[LightCrazy]

There is a lot of talk about not letting the 18650 batteries get too low in voltage. How does the circuitry (sp) work in the Fenix light? I know the lights are regulated, but at the point that the battery is low enough that it cannot keep up, does the light drop the "Turbo" mode? Is there a way to know that "gee, i better test this battery voltage"? Or does the light give an indication. I know my Pelican 7060 gives a quick flash off and on when the battery is getting very low, so ou know the light is about to go out soon.

Thanks. And I hope everyone had a safe and enjoyable Labor Day!!!

well, having regulation on the flashlight is different from one that has a cut-off voltage. A lot of lights do not have this cut off voltage, that is why for lights like this, it would be best to use cells with protection since the protection circuit would kick in when the battery is dangerously low.

Normally if a light cant go into turbo or high, the battery's about to go. never keep it for long periods on low voltage, i have ruined RCR123's in the past because of this.
