Battery Cell Configurator — Simplifying Pack Design

The Battery Cell Configurator is a powerful online tool designed to help hobbyists, engineers, and e-bike enthusiasts quickly design battery packs. By inputting your target pack voltage and capacity, the tool automatically calculates the optimal series (S) and parallel (P) arrangement of individual cells to meet your specifications.

Users can specify the type of cells (Li-ion, LiFePO4, NiMH), cell capacity, and even adjust the nominal voltage for precise pack configuration. The tool also estimates total energy (Wh), weight, and suggests appropriate BMS (Battery Management System) and fuse ratings. It provides warnings if the calculated C-rate or currents exceed typical safe values, ensuring safer pack design.

Additional features include a visual SVG representation of the series × parallel layout, CSV export of calculations, and quick-copy options for summaries. For advanced users, it allows fine-tuning parallel strings and voltage adjustments for precise applications.

This configurator streamlines battery pack planning, reduces errors in manual calculation, and helps users quickly compare design alternatives before assembly.
