Low voltage warning: When the battery voltage is too low, the LED indicator on the side switch will start to flash quickly. Please charge the battery.
Low voltage protection: When the voltage is lower than 3.0V, the flashlight will automatically step down. If the voltage is too low, it will automatically shut down. Please charge the battery.

The problem is the switch on/off. Now it works not perfectly but it works.
