Why is it okay to connect the capacitors like this
Well it is also "a maximum voltage when fully charged" that is kinda the same thing :) look you have a cap charged to 0 volts. You apply voltage V to it and the current starts to flow and the cap starts to charge.
Is it necessary that a capacitor stores energy but not charge?
A charged capacitor has stored energy due to the work required to separate charge, i.e., the plates of the capacitor are individually charged but in the opposite sense

6 FAQs about [Capacitors are stable with or without charge]
Does a capacitor charge faster than a battery?
A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly. How much can we charge? When connected to a cell or other power supply, electrons will flow from the negative end of the terminal and build up on one plate of the capacitor.
Why does a capacitor have a higher capacitance than a plate?
Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.
What happens when a capacitor is fully charged?
The flow of electrons onto the plates is known as the capacitors Charging Current which continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage Vc. At this point the capacitor is said to be “fully charged” with electrons.
How are capacitors characterized?
Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance which depends entirely on the geometry of the capacitor (the physical configuration of conductors).
What does a charged capacitor do?
A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on: the voltage required to place this charge on the capacitor plates, i.e. the capacitance of the capacitor.
What is the difference between a battery and a capacitor?
A battery stores electrical energy and releases it through chemical reactions, this means that it can be quickly charged but the discharge is slow. Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference.
