First of all I know Voltage goes Up in Series and Capacity/Total Current in Parallel.
But I have confusions,
For example let’s say we have 2 Li-ion cells,
Both 3.7 volts and 2000 mAh or say 2 AH.
When their volts go up to 7.4 volts why doesn’t it go to 4000 mAh as well?
Where does the other 2000 mAh go?
I know because Battery is now delivering current at faster pressure (volts) but it still doesn’t explain why battery is not called 4000 mAh after It’s put in series.

A hallway has two doors at either end. Each door can handle 100 people per minute. How rapidly can people go through the hallway?
a) Even though each door can handle 100 people per minute, everybody who goes through the hallway has to go through both doors. Therefore, the hallway can only handle 100 people per minute
b) In normal circumstances, the doors and the hallway are not pushed to their limit; how many people go through the hallway usually depends on what is on either side of the hallway more than the architecture of the hallway itself
Applying the analogy:
a) The current rating of a battery is a maximum of how much current can go through it. When two batteries are connected in series, all the current that goes through one also has to go through the other
b) The current rating is again the maximum current that can go through the battery. How much current actually goes through the battery usually depends on what the battery is connected to.
