Very nice video and great information, i appreciate all the work that went into this video, however, myself along with many others can't stand computer voices doing the talking, it was hard to tolerate it the whole time.

I looked at your spot welders, heavy duty industrial machines. I bet they work well! Probably too heavy for hobbyist battery builders?
