How is it possible to insert srews into lithium ion cells? this peicture I found shows that it has been done. but no discription of how. is it possible to buy cells that are made sor srews or bolts?
two of my builds. soldering isn't really recommended but i have a technique that takes less than a second. i soldered these in 2014 and they're still holding up really well
i know soldering to batteries is not good and all the companies use sonic welding to accomplish connecting their terminals to the cell.
i've read that a tide buzz can be used as a sonic welder. and when modified it can even deal in some metals.
