How do I increase the voltage limit by connecting same capacitors?
Connecting two identical capacitors in series, each with voltage threshold v and capacitance c, will result into a combined capacitance of 1/2 c and voltage threshold of 2 v. However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective …

Supercapacitor | Capacitor Types | Capacitor Guide
While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.
