I had [what I thought was] an epiphany last night:
I want to build an 18650 battery pack but I don’t have a spot-welder. I don’t really want to buy one. I was going to have a go at soldering the packs but I’m aware that it’s not a great idea. I was going to try anyway.
I remembered back to when I was an electronics engineer (technician mostly) and we used to use a low-temperature solder. I was wondering why you couldn’t use some of this low-temp solder to solder nickel strips to 18650 battery packs.
Maybe a higher-resistance?
Solder would melt when battery pack was under load?
Keen to hear thoughts.
