充电模块使用不带过放保护的tp4056模块， 电池、微动开关和换向开关使用原装的。 The charging module uses tp4056 module without over-discharge protection. Batteries, microswitches and commutation switches are original. 这个喜欢数令我意外。我说明一下这个的来源吧。我是中国学生，在中国有很多这种生产电动工具的工厂。2018年一家企业在我学校举办了比赛，提供了这个电批作为马达。我用不到它，闲置又有点可惜，于是设计了一个外壳。 I was surprised by the number of favorites. Let me explain the source of this. I am a Chinese student. There are many factories that produce electric tools in China. In 2018, a company held a competition in our school and provided this batch as a motor. I don't need it. It's a pity that it's idle. So I designed a shell.
