Hello everyone,

In this Video: https://youtu.be/Pb7w1uqetj8 I will show you, how to make a 18650 battery pack for applications like : Power Bank, Solar Generator, e-Bike, Power wall etc.The fundamental is very simple : Just to combined the number of 18650 cells in series and parallel to make a bigger pack and finally to ensue safety adding a BMS to it.

At the end of this project, I made a custom 3D printed enclosure for the battery pack.

Actually, this is pretty dangerous. A good and safe battery pack should have cell balancing electronics.
