Capacitor solar container slow discharge

Dielectric capacitors known for high-power density and fast charging/discharging suffer from thermal stability and failure at high temperatures. Although a big investment, their performance and the preservation of battery longevity they provide is worth it, in my opinion. These capacitors will easily pass 1500 Amps and would look like a short circuit if just connected to the DC bus - resulting in welded breakers, likely damage to the. I charged it using a 18650 battery through a 5V step up converter for a couple of. The main idea is - to make a device similar to solar powered power banks, but instead of Li-Ion batteries, use supercapacitors.
