Storing charge in capacitors to use to charge a battery
So a 100mAh, 3.7V battery contains roughly 0.37Wh, or 1332 Joule. Replacing a 100mAh battery would thus require not 4x 1000uF caps, but around 196F worth, or 196,000 x 1000uF capacitors. Even then, the capacitor has a discharge
High-voltage capacitor in a low-voltage system
The capacitors filter this drop by supplying the appropriate voltage to keep the circuit smooth. As the voltage rises back up again, it recharges the capacitor. A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it.

You should also have a large low ESR capacitor (100~1000uF) across the controller''s power input rails, to suppress voltage spikes caused by inductance of the power supply wires. If the controller does ''active freewheeling'' AKA ''synchronous rectification'' and/or dynamic braking then this capacitor also helps to slow down the voltage rise caused by the

This isn''t worth an answer but I''ll note that powerful stereo installations sometimes use big capacitors to do the battery''s job for big bass hits. – Sort of Damocles. 1 Farad = 1 Amp-second per volt. Even a cheap car battery is around 60 Ah... your capacitor boost pack is about 50x lower capacity than the battery ! Good luck starting
What does the Voltage Rating on a Capacitor Mean?
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it''s best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum
Connecting a super capacitor to the solar battery in parallel
Putting a large supercap in parallel with the battery does not change the terminal characteristics. You still would have low voltage trips at 10.5V, and still classify as fully charged at 13.4V. The charge stored in a capacitor is: W = 1/2 * C * V^2. For a capacitor in parallel with a 12V battery the total charge in the capacitor would be:
