Not only should you not do this with alkaline batteries, but its especially dangerous with lithium batteries. One battery can discharge into another, damaging it or causing a fire!
If you ever need a larger battery, you should upgrade to a larger battery! Like this one which is twice the size and has twice the capacity.

Vous pourriez alors vous demander '''comment les fabriquants font-ils pour vendre des packs d'accus qui branchés en parallèle'''?
These two packs are clearly two and three batteries. Since they are 3.7V they must be in parallel. Isnt this unsafe?

The answer is that these batteries are assembled by a company that is experienced and certified to test and assemble battery packs. The individual batteries are tested and sorted by machine so that each pack has matching batteries with the same capacity and internal resistance. Individuals do not have this equipment, which is why you should not try to make your own packs.
So the next question is whether you can connect batteries in series to get higher voltages?

This is also discouraged because the battery wont be able to be charged in a balanced manner. You should purchase a lithium ion pack that is preassembled.
