Tried both of my T4’s with the 14100 battery today. The tailswitch would light up but not the main led. Does the driver not recognize voltages between 6 and 3.4 ish?
It recognizes the voltage but it decides to not work. The working voltage of this battery falls right in the do not work region of the T4 driver:
5.4V: Fully depleted Li-ion X2;
3V: Fully charged alkaline X2.
