    Why don’t you enable English and German subtitle in all of your videos? In that way, you don’t have to create another video in German. 🤔

    Instead of joining the cells in packs permanently by soldering or welding, I join the cells with strong mini magnets. Then I can take the pack apart easily whenever the cells need charging. This way I can charge a lot, or all the cells at once in parallel, sharing the same 4.2 V voltage. No need for balancing when parallel charging. Each 18650 cell is current protected by a fuse. After charging I can (re)assemble the cells in series/parallel packs with magnets in different configurations, depending on the voltage and current demands for any desired purpose. This is the most cost effective, the safest and most versatile way of using and charging 18650 cells. All you need is a good quality power supply, that can handle a constant current according to the number of cells to be charged in parallel. I charge at 300mA per 18650, so a 10A power supply will charge about 30 cells at once. Obviously, it takes some time to take the pack apart and to reassemble it. But when using magnets this can be done reasonably fast.
