How to raise capacitor voltage to use a capacitor bank as a battery?
According to my calculations, 5 of them in series would give me the energy capacity close to a 44Ah, 12V car battery (about 0.5kWh), which is convenient, because the voltage rating of the arrangement would be 13.5V. So, in theory, I could replace my car battery with a capacitor bank that costs 10x more.
Replacing a Motorcycle Battery with a Capacitor...
For a capacitor bank to keep, say, 10W of lighting going for more than a minute or two will require a huge capacitance. The cost for that plus the necessary charger/regulator to prevent over-voltage and lights burn-out will almost certainly be much more than the cost of
Parallel Supercapacitors with LFP bank
I just may be adding a capacitor bank to my battery bank. Using an AC clamp amp meter, I was a bit shocked to see 23 amps of current ripple on the main battery cables. And this is running just 30 amps DC at 57.2 volts. Just some large electrolytic caps at the battery, on the far end of the 8 foot DC cables, may be able to take some of that off
eli5:Why not use capacitors in electric vehicles instead of
The energy density of capacitors is much lower then batteries. So for the same size and weight you get a lot less distance with a capacitor bank then with a bank of lithium ion batteries. Supercapacitors may still be useful for cars though. They are able to provide much higher current then even the best lithium ion batteries.

Ultra capacitors, any value on LiFePO4 battery bank?
When my battery bank was 48V 600Ah I found I had large ripple current and battery temperature increases. I purchased an Eaton XLM 62.1V 130 farad supercapacitor. I dump all excess solar to loads of opportunity. With the capacitor in parallel with the batteries it greatly decreased ripple current and lowered battery temperatures.

Capacitors store energy so, yes, you could replace the batteries with a capacitor bank. To size the capacitor bank, you''ll need to specify the required energy for the 5 second interval, which you haven''t done, as well as the allowed change in voltage across the bank.. The energy stored in a capacitor is proportional to the square of the voltage across.

What is a capacitor bank?
Capacitors store electrical energy, and when grouped together in a bank, they help with power factor correction and reactive power compensation. Essentially, capacitor banks optimize the energy use in systems by reducing losses and stabilizing voltage levels. Capacitor banks come in various forms to meet specific needs. These include:
What is a super capacitor bank?
Super Capacitor Banks: Known for their high-power capabilities, these are often used in specialized applications such as electric vehicles or large backup systems. Variable Capacitor Banks: These are adjustable and can change their capacitance according to the power factor needs of the system.
What are automatic capacitor banks?
Automatic capacitor banks: These banks have variable capacitance and are controlled by a controller to adjust the capacitance based on the system’s load and power factor. They are more efficient and flexible than fixed banks. Capacitor banks play a critical role in improving the efficiency, stability, and cost-effectiveness of electrical systems.
How many volts is a planned bank of capacitors?
Also, a point of note is that even though the planned bank has a capacity of 16.2v it will only operate at the voltage its charged too, so if the car charges at 13.5v then the bank will be charged to 13.5v. Its also important to balance the load across a serialized bank of capacitors to prevent damage.
