4200mAh 3.7V 18650 LiPO Battery Used for The Smart Double-Sided Flashlight
The double-sided flashlight with 4200mah in-built high-performance 18650 lithium ion battery, have six separate modes that start from the lowest setting of just 20 lumens to the highest at 1500 lumens. A simple touch switches you between the modes, making it easy and quick to adjust.
There are many advantages to using the flashlight with a bike. First, the front LED is as powerful as a motorcycle headlamp. Second, the back LED creates a spot of light on the full area you are moving in. At night, comparatively speaking, you will be safer while on the road, because you will be completely visible to other vehicles.
It can be recharged with any power source; just use the USB cable in the kit. The charging starts automatically after connecting. It knows when the battery is fully charged and automatically stops charging to prevent the lithium ion battery overheating and overcharging.
The flashlight more laconic, smooth shaped, stylish, and comfortable to carry. Totally ergonomic shape, small weight, and no useless details make it the most comfortable and enjoyable flashlight available. It doesn’t take much space in your backpack, pocket, or purse.
Due to the intrinsic value of metal, once made it is rarely wasted; and with good recovery systems in place, it’s possible to achieve recycling rates of 90%. The entire body is made from aluminum, which is infinite in usage. When the lifecycles of both plastic and aluminum are considered, it becomes clear that aluminum is by far, the most environmentally friendly option.
The flashlight is armored in premium aircraft-quality aluminum and there is no chance that moisture will penetrate inside and damage the inner components. Snow, rain, showers, or storms won’t take it out of service.

Lipoly battery Life?
Standard: After 500 cycles, the capacity will be <80%.
It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.
What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answeri we gave is that you do not have this worry about these.
Because all lipoly battery we produced have reasonable tolerances:
Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.
What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.
