Tinning and soldering to EVE 50PL 21700 LiIon cells.

Here I show how to solder such cells properly. Please note: I have 2 identical soldering stations, and the "400°C" temperature I show in the beginning was set at the wrong one. The soldering shown happens at my standard temperature of 330°C. Soldering station used: JBC "Weidinger Edition". Solderin tip: C245966
