Spot welding! Spot welding is easy. The first step is to set the amount of energy or the pulse time, depending on the welder. After that, it's a matter of placing the nickel strip on top of the cell group you wish to weld. The welding electrodes need to be pressed down with a light amount of pressure.
To make a traditional battery pack, 18650 cells need to be connected together with a pure nickel strip. Nickel strips come in various lengths, widths, and thicknesses.
It’s a bit hard to find exact figures that everyone agrees on, but generally speaking, a 0.15mm thick piece of pure nickel strip can support about 1 amp of current for every millimeter of width. The current limitations of a battery pack are defined by many factors, one of which is the series of connections between parallel cell groups.
Common battery packs (a 25A peak from 5P?) uses 0.15mm thickness for 5A per an 8A-rated cell. A 0.20mm thick nickel ribbon is common for the popular 10A rated “high-capacity” cells, like the LG MJ1, Samsung 35E, and the Panasonic GA. Currently, the builders’ dilemma happens when using a high-amp cell (15A-30A).
The extra 0 at the end simply means that it is a cylindrical canister cell. Compare this to the well-known AA battery which is a 14500. A 14500 is 14mm wide and 50mm tall, and again, the trailing 0 simply denotes the cylindrical shape of the cell. In this article, we will show how to spot-weld together a battery pack made from 18650 cells.
As I pointed out, the positive tip of an 18650/21700 cell is fairly well isolated from the jelly-roll. This means that you can solder, spot-weld, maybe use fuse-wire, or use any other method that works for you. However, the negative end (especially the center spot) is sensitive.
