Details

The circuit board is a precision component. After receiving the package, it supports 7 days without reason to return the product without opening the original package. After the original package is opened, no return is provided. After sale, please consider whether you have the ability to install it manually before purchasing. Do not purchase if you do not have the ability to install! Our company does not provide trial play/trial loan/trial service. Thank you for understanding!

Specifications
Circuit control: Buck circuit, constant current, to ensure stable output after 5.8-12V power supply
Dimensions: 10.2*22mm (width * length)
Reverse connection protection: unique reverse connection protection design, no need to worry about burning the battery
Pin definition: The pad is specially designed for the 658nm driver board. You only need to arrange the pins in a triangle and solder them naturally.

Note: In order to ensure safety, it is recommended to use two imported 3.7V lithium cell with protective plates (16340, 18650, 14500 and 18500 power supply). Do not use bad batteries because of the internal resistance and discharge performance of the double lithium battery. The requirements are high, and the use of more than two sections of cylindrical lithium batteries without protective plates is particularly prohibited. If there are three cells, one of them has large internal resistance, fast discharge, and overdischarge, all the step-down chips start working at 5.8-6V.Even if there is undervoltage protection, it will not help. The circuit is out of control, which will directly cause a short circuit. It can produce explosions, and the power of steel shell batteries is very large. Of course, the percentage of this possibility is not large, but as long as it happens, the consequences will be disastrous!
