Welcome to step 1: our Lithium-Ion battery calculator. Here you can start the process of getting the right cell model(s) and configuration for your battery requirements and learn about capabilities and limitations of batteries constructed with standard Li-ion cells. Please note: All prismatic cells swell approximately 10% in thickness over time. Please allow at least 10% additional room in your application for swelling for overall cell/battery thickness.
