In this video, I build a powerful 60V 40Ah battery pack using 128 high-capacity 21700 Li-ion cells. Perfect for e-bikes, scooters, and DIY energy storage pro. Using the battery pack calculator: Just. . Whether you're planning a DIY battery build, assembling power packs for robotics, electric vehicles, or energy‑storage systems, this calculator simplifies the process of determining the correct number of cells required in both series and parallel configurations. When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity. This means that the specifications of the cell will be fixed.
