如果你能购买到“四方接线螺母”，那么你可能根本不需要焊接，直接使用四方接线螺母即可完成电池连接。不同的地区“四方接线螺母”的名称可能大不相同，需要各位自行找到合适的搜索关键词进行网购或线下购买。“四方接线螺母”的图片如下：

If you are able to purchase "square wire nuts", you may not need to solder at all; simply use the square wire nuts to complete the battery connections. The name for "square wire nuts" might vary significantly in different regions, so you will need to determine the appropriate search keywords for online shopping or find them in stores on your own. A picture of the "square wire nuts" is as follows:

使用“四方接线螺母”连接电池的时候，需要注意本方案中的所有m4铜螺丝、弹簧以及打印件的螺丝孔洞需要根据“四方接线螺母”的螺纹型号进行匹配。

When connecting batteries with "square wire nuts", note that all the m4 copper screws, springs, and the screw holes in the printed parts in this plan need to be matched with the thread model of the "square wire nuts".

大电流使用的时候需要根据所需电流来匹配所用的铜线，避免过度发热。

For high current applications, it's important to match the copper wire to the required current to prevent excessive heating.
