Step 1: Things Needed for the Battery Pack
You have two options one is to solder the batteries and then make your connection series or parallel or mixed
i have found that this 18650 battery holder works just fine and you can reuse them for other projects.

Step 2: How to Make the Battery Pack
In the picture, you can see a very easy diagram on how to solder the wire
keep in mind that the positive + and negative - terminals have to have the same length
to keep the pack balanced that's a tip for future arrangements of combined series and parallel connection
Step 3: Inserting the Cells
Is very easy we will alternate the cells when we gonna put them in the first cell up the plus + terminal
