U mnie od kilku dni na 14500 4,2V - nie przewiduję problemów

Drive parameters
1. The flashlight is powered by a 1.5V battery or a 4.2V lithium battery. Switch the flashlight on or off by the tail switch (full click) or switch mode (Half-press).
The maximum output current is 0.5A when using a 1.5V battery, and the maximum output current is 1.5A when using a 4.2V lithium battery
2. Battery judgment function: When the voltage is above 2V, it is judged as a 4.2V battery, and when the voltage is below 2V, it is a 1.5V battery. It does not turn on when powered on by 2-2.8V.
3. Low voltage protection. When using a 4.2V battery, the voltage will flash 3 times slowly when the voltage is lower than 3V, and it will automatically shut down when the voltage is lower than 2.8V. When using a 1.5V battery, there is no low voltage protection.
At 4.2V, strobe (100%), slow flashing (30%), beacon (30%), battery detection (1%) SOS (20%), the above is the maximum brightness ratio. "
