So, I want to make a 18650 battery pack but don't have access to a spot welder. I'm wondering whether a FX-888D would be good enough to do the job quickly and so minimize risk of damaging the cells.
If yes, any other tips to avoid overheating?
And finally, although I can probably get pure nickel strips; they'll be be hard to come by most likely. Could I do the job with copper wires or copper strips? If so, what would you recommend?
