Lipo Battery Cell Capacity Fast Calculator
Enter basic cell dimensions to estimate Capacity (mAh) and Energy (Wh). Results are approximate.
Assumptions (editable in code): volumetric energy density (approx.) — LCO(3.7V)≈600 Wh/L, LMO(3.7V)≈500 Wh/L, NCM(3.6V)≈620 Wh/L, LFP(3.2V)≈350 Wh/L, LCO(3.8V)≈650 Wh/L, LCO(3.85V)≈680 Wh/L. C-rate derating (usable energy): 1C=0.98, 3C=0.94, 5C=0.92, 10C=0.88, 20C=0.82. For accurate design, please validate with cell vendor datasheets and lab tests.
The product is equipped with a rechargeable battery (lithium-ion battery).
If battery fluid gets into eyes, do not rub them. Rinse thoroughly with clean water such as tap water and consult a doctor immediately.
