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.
A spot welder relies on a high-resistance connection between the metal and the electrodes in order to generate enough heat to form a weld. So, when you are pressing your probes down onto the battery, use just enough force to remove any air gaps between the surface and the metal.
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.
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.
30 amps ÷ (1 amp x 7mm) = 4.3 strips. So, if you are wanting to build a battery pack that is capable of supporting a 30 amp load continuously and you are using a 7mm wide nickel strip that is 0.15mm thick, you are going to need to use at least 5 strips to connect your cell groups.
