@sweetgyy These literally sit in that box and do nothing but buffer my solar panels before my grid-tie inverter so I don't have to worry about it when the sun goes down. They're pretty much useless unless you're buffering something. This scooter still uses batteries.
How long will it take to recharge those capacitors, once they're out of power? I've heard recharging is very fast.
Makes me wonder if it wouldn't be better to charge these ultra capacitors with a windmill, rather than deep cycle batteries. Seems like the capacitors could accept all the energy produced as the wind blows so none is lost no matter how short a time the wind is blowing.
To my knowledge, they will charge as fast as the charging source can handle. But since I have no charger that produces more then 2 amps, it's takes quite a while. I'm going to use them for a mobile solar charge type thing most likely, as like you said, they take on every bit of charge no matter the duration(or in this case, no matter how much cloud cover). This bank is only the equivalent of a 12 volt 7 amp hour battery.
@asphyxsia I don't even remember how I calculated that value to be honest, lol. And I don't even know how it would be possible to account for the linear voltage drop in an equation. I just now punched in the numbers into a joule calculator, and it's 10935 Joules/capacitor*24 capacitors = 262440 Joules = 262440 Watt Seconds = 72.9 Watt Hours. So, I'm not really sure how to get from watt-hours to amp hours if the voltage continually changes, lol (72.9watts/32.4volts=2.25Amp hours)?
@asphyxsia And in a 16.2volt configuration, it would be 4.42 amp hour? Because I have 24 capacitors at 2.7 volts each, I can't make a 13.5volt bank, because I would need one more capacitor to make it 5*2.7v=13.5volts, and then it would be 5 sets of 5 capacitors in series for 13.5Volts at 3000 Farad = 273375Joules = 75.94 watt/hours = (75.94/13.5v = 5.6 amp hours). So I have no clue. You're probably right.
The sheet under the multimeter in my video shows the configuration and values for the bank, I guess I should've displayed it at the start, lol
I have 24, 3000F capacitors in the box. 12 in series, two strings in parralel, for 32.4V maximum at 500F.
I can also arrange them for 16.2V at 2000F with a few alligator wires. I have them connected with aluminum duct tape on the outside of the box, so in case of a short, the tape just vaporizes like a fuse.
i thought the trp was terrifying especially when you would face the cam down, if felt like u were gonna crash any moment

Do you feel the boost of charge difference between a ultra-capacitor bank and a battery bank?

question? why ucapacitors when there's lithium ion and all of that ?

@72fr250 i thought it was more like a 4.6 Ah battery...
32.4V 6000F = 32.4V 6000 Aseconds = 100 Amins = ~1.7Ah @ 32.4
32.4 / 12 = 2.7
2.7 * 1.7Ah = 4.59 Ah @ 12V.
What did i miss?

Way to go, Buddy! Glad you survived the ride while doing the camera work. Excellent!

Dude! Awesome. I have done a ton of videos about super caps, and I wanted to start my car with them. This video has inspired me to do just that!
So cool!
How do you have your bank configured? are you using 2600f caps? 300f caps?
Nice!
