Accessories Required:
18650 battery*2
M3 *10 screw *4
Charging protection board*1
Wire nickel strip
The following are the detailed steps: First, prepare two 18650 batteries: Use a soldering iron or spot welding machine to connect the two batteries in parallel (1. The positive electrodes of the two batteries are soldered together, 2. The negative electrodes of the two batteries are soldered together), weld the connected battery pack from the positive and negative electrodes, and connect one wire to the positive and negative electrodes of the protection plate (please do not connect incorrectly, the protective plate will be damaged), and wrap the positive and negative electrodes with appropriate tape
Take out the prepared printout: Insert the switch first

Then put the installed battery pack and protection plate directly into the empty space, pay attention to the position of the wires, ideally all accessories can be directly fixed
Check whether the switch can be used normally, if not, please adjust the position of the protection plate It is recommended that after the switch is used normally, you can use hot melt adhesive to fix the protection plate (please do not apply glue near the switch to prevent the switch from being fixed and causing it to be unusable)

充电保护板购买链接： https://e.tb.cn/h.6lDqWPcjmCAPvIt?tk=yDOjVeGCZNu

需要的配件：

                       18650电池*2

                        M3*10螺丝*4

                        充电保护板*1

                         导线+镍带

以下是详细步骤  首先准备两节18650电池 使用烙铁或者点焊机将两个电池并联（1.两个电池的正极焊接到一起  2.两个电池的负极焊接到一起）将连接好的电池组从正极和负极各焊接一条导线连接到保护板的正负极（请不要连接错误 会导致保护板损坏）适当胶带包裹正负极连接处

取出准备好的打印件：先把开关装进去

然后把已经安装好的电池组和保护板直接对准空位塞进去，请注意导线位置，理想状态下所有配件都可以直接被固定

检查开关是否能正常使用，如果不能 请调整保护板的位置  建议开关正常使用后 可以使用热熔胶固定住保护板（请不要将胶水涂抹在开关附近 防止开关被固定导致无法使用）

将上盖安装 使用M3*10螺丝固定
