Battery indicator
The flashlight has a power indicator on the neck. When the flashlight is turned on, it will light up. Different colors represent different remaining power. The corresponding relationship is as follows:

Indicator status

Remaining battery power

Recommend operation


Very adequate(100%-80%)

Safe to use



Normal use



Pay attention to remaining battery

Flashing red

Running out soon(10%~1%)

Charge the battery

Note: The battery indicator function is a 3650mAh capacity 18650 rechargeable lithium-ion battery. It is based on the test data in the laboratory. It can work normally when using a 18650 rechargeable lithium-ion battery, and may be due to changes in the battery and the environment. An error has occurred.

Battery replacement:
Unscrew the tail and load the nominal battery. Note that the positive direction of the battery is aligned with the lamp head, and the cylinder head can be tightened to work.
★ The brightness of this product is extremely high. Please do not look directly at the illuminator to avoid visual damage.

★ Intelligent downshift and low pressure warning:
In order to ensure the extension of the lighting time of the flashlight, and not to damage the battery due to over-discharge, the flashlight circuit adds the functions of intelligent downshifting and low-voltage warning: when the flashlight detects that the current gear has very little remaining power, it will automatically lower the gear until Only the low light is left, turning off the flashlight will unblock the gear.
If the power is about to run out when the low brightness is detected, the flashlight will flash 3 times every 5 minutes to remind the low voltage, and the battery should be charged in time to avoid damage to the battery.
★ If the O-ring of the flashlight is damaged after long-term use, please replace the O-ring in time to maintain the waterproof performance of the flashlight.

★ When the product is not in use, pack the product away from the damp environment.
