Interesting video to watch the capacitor charge... However, all capacitors have an upper voltage limit, in this case 2.85 volts which should never be exceeded, even for a short time, and especially when charging. So temporarily increasing the external power supply to higher than 2.85 volts to speed up the charging is not a very good idea. The charging process shoould apply a steady 2.85 volts (actually, less) and not exceed that no matter how long it takes to fully charge the capacitor. For the video, it would be better to simply cut the video and let the cap continut charging and then resume the video within 1 or 2 minutes of full charge. Also, your capacitor, presuming it doesn't already have a small charge on it when you started, is essentially a dead short that can trip the short-circuit protection of the external supply. Tripping will depend on the particular power supply response time and the existing charge on the capacitor when charging begins. To protect the power supply you should place a 0.5 ohm 1 watt resistor in series with the power supply to present a minimal resistance higher than a dead short. Also, it would be more instructive if someone was talking and explaining what is going on... Playing music is a distraction and provides no value to the video.

I fell asleep while dreaming of sheep jumping over the fence 🐑 but before that, I was wondering about an eBay item, LSUC 2.8v 3000F super capacitor x6 in a six pack module import from South Korea $150 + 65 shipping, is it worth it? How would I charge it? Could connecting to a 12v car battery while engine is running, 14v would that be good to use to charge 16.8 volt or by solar panel low amperage might take forever, but it gives 20v under direct sunlight, would that be too much voltage even though the amperage of the solar panel is so low and plus, the voltage might drop upon load to lower than 20v I think that’s what I will do, keep it charged by solar but then at night it will get discharged, and the final question I have is what type of diode should I use for keeping it isolated and not allow it get discharged and fry the solar panel? Thank you for your helpful comment

Dear sir, Good day This is preethesh kumar from India I have already purchased 3000F, 2.7V x 18 pcs I connected it series I have technical query regarding some conditions while charging and discharging. Question 1 1) sir, what is the max charging current of this module. 165F ,48V.i have 50 ampere 48volt dc power supply source if I charge it directly will it damage the supercapacitor. If not possible to charge directly with 50 ampere can I use high wattage resister in series. For 165F, 48V supercapacitor module can you suggest the resistance value and it's wattage for charging my concern I need fast charging. Question 2 2) sir, once 165F, 48Volt supercapacitor got charged fully with 48V, 50 ampere power supply source if capacitor got charged fully if I keep continue power supply on to the terminals of the capacitor after fully charging will it consume current after fully charging and or will it damage any heating life decreasing plz check and inform me. Question 3 3) what is the full output current of fully charged 165F,48V ultra capacitors. Please reply for the above questions Thank you

I have 6 super capacitors. Each are rated at 2.85 volts 3000 farads. They are completely discharged and I'm unable to charge them using a SKYRC iMAX B6 mini. Do I need a resistor? If I do, what ohms/watts? Will a 15 amp diode work? What settings do I use on SKYRC iMax because mine can't be adjusted on the fly...I think? I have multiple volt settings 2V, 4V, 6V... and max amps the charger is capable of is 5 amps. I'm looking to charge each super cap to 2.4 volts x 6 to equal 14.4 volts which is the voltage in my car. After I charge them to 2.4 volts each they will be assembled or should I charge the whole bank at once? After I successfully charge the capacitor a bit can I use a EVERSTART 750 Amp Jump Starter to fully charge the caps so it will be faster?

Sir, if the capacitor of 3000 F,2.85 volts charged fully with 2.85 charging volt.after charging of capacitor is completed fully if these capacitor is kept parallel on the power supply giving 2.85 volts, capacitor charged volt is 2.85 V is it overcharge capacitor or it will damage. 2) if we connect 30 pcs of 3000F,2.85 volt capacitor and connected in series and charged with 35 amps current will it charge quickly
@cagrahskal4706

1. If you do not exceed 2.85 supply voltage it will not damage the capacitor, it may be supplied constantly. 2. Normally you can charge a capacitor with up to 20 Amps. If you connect them in series still you can charge with 20 Amps and should limit current to 20A, but the supply voltage needs to be increased to 2.85x30=85.5V 3. The capators sucking Ampere determines the charging time. You may charge it with 2Amps in 10 mins or charge it with 20Amps in 1 min. 4. Read the specific capacitors data sheet to find out what is the caps max charging ampere and then limit your charging current. (This capacitor shown in the video supports up to 25 Ampere charging current)
