I have soldered many NiCad packs using solder braid for connections for=20 Radio Controlled model airplanes. No problems short term or long term,=20 carefully monitored. I am concerned about any kind of Lithium cells without more information. About 1960 (Lab Tech then) we assembled thermocouples from wire spools.=20 Sometimes we cobbled up a spot welder by charging a capacitor with=20 whatever power supply that was handy and switched it across the clamps=20 with a common knife switch. Play with every thing until it met=20 requirements. First quality check was pull on it, second was to try it=20 and see if it works. Insurance was do more than one if it is going to be=20 hard to repair. Another way was to use a fuse between the power supply and the knife=20 switch. New fuse each connection. Enhanced by using strands of wire from=20 zip cord. Eliminating the power supply and simply using wall power=20 worked but was inconsistent and dangerous. We did not have OSHA then. Remember though, thermocouples did not involve much power in use.
