To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
Battery capacity is measured in ampere-hours (Ah) and indicates how much charge a battery can hold.

Electrolytes facilitate the flow of electricity in batteries by allowing ions to move freely between electrodes, thereby generating a flow of electric current.
Electron Flow: Electron flow is a fundamental aspect of electricity generation in a battery. When a battery discharges, electrons move from the anode through an external circuit to the cathode. This flow generates an electric current that powers devices.
Batteries are devices that store chemical energy and convert it to electrical energy. A battery consists of one or more cells, each of which contains a positive electrode (the anode) and a negative electrode (the cathode), separated by an electrolyte.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
When the battery is connected to an external circuit, such as a flashlight, the electrons flow from the negative electrode to the positive electrode, producing an electric current. This process is called oxidation-reduction (or redox for short). The chemical reactions inside the battery generate heat, so batteries can get hot during use.
For example, in a lithium-ion battery, lithium ions travel from the anode to the cathode, resulting in energy release. Electron Flow: Electron flow is a fundamental aspect of electricity generation in a battery. When a battery discharges, electrons move from the anode through an external circuit to the cathode.
Batteries store energy in the form of chemical reactions. The most common type of battery is the lead-acid battery, which uses a chemical reaction between lead and sulfuric acid to create an electric current. This reaction produces electrons, which flow through the battery to create an electric current.

On the other hand, the calendar aging takes into account the SOC, temperature and time. There is no formula as such for the battery degradation calculation.
Finally, two simplified formulas, able to evaluate the efficiency and the auxiliary losses of a NaS BESS, are presented. The overall efficiency of battery electrical storage systems (BESSs) strongly depends on auxiliary loads, usually disregarded in studies concerning BESS integration in power systems.
