OK ... reason for asking. I started to order my mini battery pack from EM3EV and was shocked by the shipping cost for the tiny battery.
I can acquire said 18650 cells locally in Houston, texas for a reasonable price. I can get a BMS off ebay for a reasonable price.
However I do not have and would rather not purchase a pulse welder for a one time use.
I was thinking I might use WBT #0800 4% Silver Solder and 12 GA copper wires between the cells.
Melting point of the WBT 4% Silver Solder is 180 degrees C -- somewhat lower than the 237 degrees C for the more common 60/40 electrical solder.
Yes I do realize this would be a bit dicey and I would have to be extremely careful about NOT overheating the end of the cell but .... ???
