Estimate the nominal capacity and stored energy of batteries connected in parallel. Enter each battery's capacity and nominal voltage. The calculation assumes compatible batteries at the same voltage and sums their ratings without accounting for age, temperature, wiring losses, or discharge limits.
Estimate a battery pack’s nominal voltage by adding the voltage contributions of cells connected in series. Enter the nominal voltage and count for each cell group. This calculator does not estimate loaded voltage, capacity, runtime, or charging requirements.
Add the capacitance values of capacitors connected in parallel to find their ideal total capacitance. Enter each capacitor value in microfarads (µF).
