Thanks, this was very helpful to watch. I have 12 old but still perfectly good 18650 cells leftover from the defect pack of an electric unicycle and I also have a Toshiba laptop the battery of which doesnt hold enough charge for more than five seconds if you unplug it from the outlet. That not even nearly enough to carry it from one room to the next. It was painful to see you try to unsolder the parts at 2:45 though,. You either need a more powerful soldering iron or let your (30W I assume?) iron heat up really high, then melt a tiny trop of solder onto the tip for better heat transfer.
