NEVER solder directly to a lithium battery terminal, ESPECIALLY one that looks like it’s been salvaged from a laptop. You can do a video on making your own spot welder
@@TechBzzodI just bought a cordless spot welder from Amazon for $35 works amazing. Also soldering on battery’s is fine.. people do it alllll the time with no issue.. just gotta be careful when you do it that’s all
Good grief… those solder connections to B+ and B- are among the worst I’ve ever seen. Please take a class on how to avoid “cold” solder joints. Step 1, clean your soldering tip to allow effective heat transfer. Step 2, …….
I know it.. that tip was FILTHY! Should be cleaning the tip before every single solder joint you make for the easiest time soldering and the best connections.. also use a touch of flux. And put some solder on the tip once it’s clean to help bring heat to what your soldering..
