I've done a lot of research and searching on CPF and can't come up with a concrete answer. I know it's safe to use unprotected 18650 cells in the Surefire U2 because the light shuts down at around 3.2 volts, so no damage to the cell. Does anyone know if the Surefire Kroma operates the same way? I have a couple of extra unprotected 18650s and a body for the Kroma that can accomodate them, just don't know if it's safe to let them rundown in the light. Any info would be greatly appreciated.
