Great video, thank you! It sounds tricky to do though if you have many different cells in your pack. I noticed with soldering too that different metals work differently. If you're spot welding and you have to constantly adjust the current for the battery you're on, that would get annoying. Plus you're risking burning holes in the cell and fuse wire. On the other hand, if you have all of the same cells in your pack, you could zip through pretty fast.
Solar Setup: 9x 320w panels, PCM60X charge controller
Battery Setup: 14x 120 cell 18650 packs, 48v configuration

Recommended Items:
Opus BT-C3100, Cell Heat Shrink, 4-Cell Holders

Correct. It differs a slight bit but you have quite a play in terms of adjusting the current. I have had a couple of cells that i know that i had to turn up a bit and you get used to that quite fast. Most of them so far have been working on same current.

Follow up on the spotwelder!

After using it for >1000 cells Im still happy with it.

Its recommended to have 16A fuse for it and slow blow (230v Version)
Links to it can also be found in the video.
