To make a 100Ah battery pack using 18650 cells, you need to know the capacity of one 18650 cell, which is typically around 2.5Ah to 3.5Ah. Dividing 100Ah by 2.5Ah gives you 40 cells (for 2.5Ah cells) in parallel; for higher capacity cells, you would need fewer. The total number may increase if you want a higher voltage pack, as you'll need to connect several parallel groups in series.
