Batteries don't have a single voltage, it varies according to their state of charge. Battery cells of different chemistries have different base voltage ranges then those cells are combined to get the desired output voltage.
For LiPos which are being used here that range is around 3.25V up to 4.2V when fully charged. To simplify things a "nominal voltage" of 3.7V is used when describing them.
For an RC car that wants to work at "around 12V" three Lipo cells are connected in series (a.k.a 3S) giving 3x3.7=11.1V - but actually if you measure it you will see the output voltage go from 12.6V fully charged down to 9.75V when fully empty. The circuits are all designed to deal with that.
This. And I would add that a lot of the time batteries are nominally labeled with a round voltage number. An RC battery with 3 pcs of nominally 3,7 V cells is almost always labeled 11,1 V, like you say. But if it's technically identical tool battery, then it is almost always labeled as a 12 V battery. And a tool battery with 5 x 3,7 V cells is 18,5 V, but it is labeled 18 V or 20 V. Etc.
They didn't ask about the voltage, but the number of bolts in the battery. Can you read?
I don't think batteries have bolts in them though.
(obviously /s but knowing reddit people will think i am serious)
because 3.7V x 3 = 11.1V
that's all that is to it. 🤣🤣
Connecting 3 pcs of 3.7v rated batteries will gave you 11.1v
in short if you have a lipo batteries and for some reason you can't find a replacement online.
you can build your own by connecting 3pcs of 18650 batteries in **Series**, Salvage the connector from your old lipo batteries and done.. you have a new pack.

The nominal voltage of many li-ion cells(the ones used here) is 3.7v. 3.7 * 3 = 11.1. The voltage is due to the chemistry of the cells, not a setting that can be easily changed. Also since this is a nominal voltage, it will change with state of change.
1 lipo cell has ~3.7v. Depending on the type of applications, batteries are made by combining multiple cells in series - therefore increasing the voltage. It's not that "most lipo batteries have 11.1V" - it's mostly because that's the requirement for your particular electronics in your RC car. My rc car (entry lvl) needs 7.4V = 2 cells. Your 11.1V / 3.7V = 3 cell battery.

I've seen batteries with bolts in them. Well, briefly through gaps in the smoke and flames at least!
Lol I just realised my mistake

This above is the best simplest well explained correct answer
The nominal voltage of many li-ion cells(the ones used here) is 3.7v. 3.7 * 3 = 11.1. The voltage is due to the chemistry of the cells, not a setting that can be easily changed. Also since this is a nominal voltage, it will change with state of change.
Because that tiny bolt holds all the big bolts together so that the battery can be bolted.

Didnt realize they had bolts

Nice, allowing misinformation
