How to make a 12V lithium battery box can be connected in series without welding, very reliable!

This one can connect three 18650 batteries in series to provide DC 12v power supply. If you expand it according to this idea, you can place more batteries. The operation is stable and reliable, and the power supply effect is first-class.
The body is made of beech wood, the template is hand-painted by me, and my signature is required when using it.
This is not a toy. It will be an important tool for me. I will continue to use this battery case in my future work. Why don't you follow me... TH-cam subscription:
