Super caps are great. You need to replace the copper wire between the terminals with a flattened out copper pipe with holes drilled in each end. :-) Also make sure image stabilization is turned on in your camera.
Your LiPo will be protected from over-current-discharge if you place a 1 ohm resistor inline, so it won't melt down while jumping another's car.
That will also protect it during your own car's startup, but allow a quick recharge of the capacitors during an engine-off jump-start of another's car.
brilliant , my good man. Simply brilliant. Thank yku for remaining focused throughout. Looking forward to the follow up.
You are one of my favorite people on youtube, thank you very much for the know how, it is improving my life greatly.
Buy some 1/2" rigid (Type M) copper pipe at home depot. Cut the length you need to connect your posts together. Take a hammer and completely flatten the pipe, then drill a hole in each end for your bolts. There is nothing better than this, and you cannot beat the price.
Great tip!
Something else you might consider is taking a 3/8" copper pipe, flatten it, then drill holes for jumper bars rather than winding the wire back and forth between washers.
I agree on this as wires tend to come out when the washer spins
i really like your idea. in spite of all the ingrates that try to debunk everything on the web keep up the great work and thank you for shareing
Cool idea for sure! Thanks for testing and making the video.
This is pretty damn cool! I'm stunned that lead -acid batts are still the status quo in the automotive market after seeing this!
There is a reason for it. Lead batterys have a VERY high reserve capacity!
Use an isolator so that the alternator charges both the caps and the battery. The battery would be "in reserve". Rewire the accessories to the reserve battery, it is usually the second wire coming off the positive.
this looks like it would also work awesomely as a cap bank for a stereo system, or as you stated, off-the-grid configuration for a mobile workshop, nice vid, and pretty decent testing
The best video about this topic! I am going to build my one today
As a former aviation electrician, I've seen caps used under far more strenuous circumstances. It needs to be over-engineered to prevent those kinds of circumstances. Caps don't pop because they're filled with explosives, obviously. They pop from thermal pressures when they're applied outside of spec. A little smoke is a secondary effect. As long as they're not _sealed_ in a metal box, any potential burst could be baffled vertically. I'd say the battery is a bigger fire hazard than a cap.
A suggestion for conductors to connect the capacitors together you could flatten copper tubing and drill holes for the bolts. I feel this would be easier to work with than wrapping multiple strands of copper wire around the bolts. I would also suggest you use plastic instead of wood as wood will conduct electricity if it gets wet or damp. Large plastic 5 gallon buckets yield a lot of usable plastic. You have many options as it is quite easy to work with.
Great idea. good luck to you on the project. I wish you the best of success.
Fantastic job ... this video gives me tons of practical information. Thanks!
I can see a lot of good things with this, Maxwell also produce a starting kit for trucks under the same principle, the only difference is that you only replace 1 of the 3 or 4 batteries of the truck with this starter, then it will always be charged because is connected in a parallel circuit. The bad I see is the cost of capacitors is they are sold for 30 to 50 dollars each anywhere I'd looked on the Internet.
Your starter needs support from the battery especially in the winter. The caps are a very good thing to ADD to the vehicle power system. Capacitors have a very quick transient response, this means that they can charge very rapidly however this means they discharge very rapidly also. Do not remove the battery. Just dont be that guy. Your capacitor bank is awesome and would compliment the system very well, watch for swelling and leaking if you see either then replace that capitator immediately or remove it for it is failing and hurting the system at this point. Capacitor have a wide variety of maximum voltages and capacitance values measured in Farads. You want POLARIZED Capacitors with at least 15VDC capacity and the higher the FARAD the better. We used to use these to keep the lowrider from stalling due to the bass lol, the amplifiers were drawing 120 Amps Peak at times and the spark plugs wouldnt fire once the battery couldnt deliver fast enough at stop lights when the alternator is not cranking enough at idle. Once installed the headlights never even dimmed on low notes. Im old school. Good luck.
Exactly! Why "replace" the battery when one can have a boost pack and battery? That way one can keep the existing, maybe reduced, capacity of the battery while adding the cranking amps of a boost pack.
My question is it safe without balancing circuit? This guy dont use ones
@@budhihart8161 Long term? Probably not. The caps probably ly start out all the same capacitance but small changes can develop over time repeated charge discharg may eventually lead to overcharging one and eventual failure.
@@budhihart8161 Because he has a large capacity as 6 in series would be 16.2vdc. But balance boards are cheap.
I am truly impressed. Good work.
I can see a combination of battery and these packs working very well in off gird applications
My favorite part about this system is the charge time. When your battery dies, you need several hours to regain the charge and thats assuming your battery has any life left in it. The caps charge damn near instantly. It would be great to have these wired in the trunk with a bypass so they are there for you in the event of the battery failing.
+Josh Denham They charge quickly for two reasons, their internal resistance is lower than a lead acid battery, and their capacity is also tiny in comparison. A capacitor can't store nearly as many amp hours in the same volume as a lead acid battery.
To the people who think he invented this setup...you're way off. First off, I and thousands of others (including Maxwell) have used these caps in series/parallel to create 12v batteries for years. His $6/each price came from before the buzz got out about these things and they were often removed in bulk from large applications for refreshing. They are carbon nanotube caps and can sustain over a million full discharges before their end of life. I've been messing with them for years.
Try $1. 46 each for 100 farad 2.7 volt supercaps. Newark Electronics.
We're your vid ?????
You sound jealous
So where is you video?
@@gabibob4479 hahaha. Late response. These things are as mainstream as it gets now.
Great video, thanks!
Just love that cackling in the background))))
Hi,
Great video - been anonymously following your work for years.
To talk apples and apples, you need around 200,000 Farads to equal a 50Ah battery. Caps are great for large impulse current though.
you can only use upper 20% of car battery capacity, because it's not deep cycle battery. have you counted with this?
I admit to being envious that you bought caps at such a great price before the price for old caps went silly. Purely for reasons of continuous power drain (ECU, alarm,immobilizer etc) let along a forgotten lamp, I would not replace a battery with this - but it would permit a smaller battery to do the job superbly. The huge current potential of the supercaps for cranking, combined with a reasonable AH from the traditional battery.
I could see supercaps being a fantastic addition to a car battery for stop-start applications - couriers etc - where the van may be stopped and started in the space of a couple of minutes. With supercaps, not only would they fully charge in time but ALSO they would allow the car battery to continue charging until the supercaps had dropped down to around 13v or so.
A shame a lot of folks felt the need to be obnoxious because the caps are no longer available surplus as easily for the right price - and frustrating that other folks seem to think they are an electrocution risk. Ah well.
Thanks for sharing the vid :)
There are already devices
like that out there.
Thanks so much for sharing this, after the years go by any feed back about your solution would be great, 👍
God Bless You Bro, Big Up to you, Everytime. Nuff Respect.
First three words of the description; "For certain applications..."
Must read and comprehend all wording.
Where do you source the capacitor and what value / voltage ?
Thanks for sharing, you got something there. I sure gonna try out.
Outstanding! My thoughts regarding the shop use is to use 12v car start batteries along with the capacitor pack. That way you still have the time required to do your work with high discharge bench tools. This will increase the life of your batteries big time as the start up power needed is coming from your capacitor bank while having additional run time from your batteries. Just don't let start batteries dip below 10 to 15 percent of full charge. I've been doing this in my shop to run a drill press, table saw, and in the future, a metal lathe and milling machine. Both capacitors and salvaged start batteries are cheap at the scrap after rejuvenation. Like 3 to 7 bucks. So you get the best of two worlds.
Interesting indeed. I'd be concerned about the reserve capacity in case of an alternator failure. I'd also be concerned about the increased load the capacitors will place on the alternator since it will be much higher than the battery while charging. However, that might be moot as it should mean that the alternator is charging the pack for a much shorter time. Not sure how all that will impact the life of the alternator and voltage regulator. Very interesting.
These capacitors are overkill for this application. I've built one using 6x 500F capacitors in parallel with a 7.5Ah LiFePO4 motorcycle battery. Works beautifully. The car has a hydraulic folding roof, which puts a big load on the system, and it works perfectly, even with the engine off. The capacitors were only $5 each on eBay. The battery was $99 and should last over 10 years. Although, I live in Australia, and it doesn't freeze here. You can't let that kind of battery freeze.
Very impressed with your "boost pack".
You are a great commentator too. It felt epic watching a battery pack!
If only I could find them for $6
How much do they cost regularly?
@@MrManerd An equivalent, quality wise to what this guy is holding/jangling around would be somewhere close to $300 at least.
There are cap setups being sold with the same "specs" but, realistically, those are very very untrustworthy, and not worth the $30 they try to get them off for. Buyer beware with capacitors. Ever had some generic or off-brand AA batteries pre-included with some gadget you bought, or remote? Yeah... Offbrand/generic capacitors are like those. They will probably die, really really fast, if they work at all. Namebrand/quality parts, will last longer, and come with a price hike.
You can get a system close to his, quality and spec wise, for around $130. But you can get a really newbie comfortable setup at around the $270 mark, since Maxwell sells a 500F pre-made bank kit at $270.
@@MrManerd also, at the time of his video, those were $50-100 each according to him in the video at around 5:26
thanx
You've really got me thinking with this video. Didn't know supercapacitors existed prior to viewing one of your videos a few hours ago. Now I'm asking myself if the solar power backup that I want to do for my home could be done with supercapacitors instead of lead acid batteries or Tesla Powerwall units.
Glad to see that there is a guy like you out there experimenting. I think soon there will be a guy like me experimenting as well. I'm guessing that I would need a lot of the supercapacitors though. Seems they charge quickly, but discharge quickly as well, yes? Just asking, as I don't know. My goal is to have enough power for two or three days at full use of the normal household appliances, including our geothermal heating system and electric tankless hot water heater (400 amps overall). Can't afford to put in enough solar to cover that kind of use; at least not yet.
Yes, this certainly is very interesting stuff. Many thanks for the video.
You should also look into using Stirling engines. They are powered by a heat difference, so you could design one to be built into a ceiling, for example, to convert lost heat into movement which could pump water or air or move a coil to produce electricity.
Similar to a steam engine, a Stirling engine produces its greatest torque at its lowest RPM. It's best to design an application that allows the Stirling engine to pump slowly and quietly.
A capacitor requires a lot more volume to store the same amount of power than a battery.
For an solar application a voltage has to be stable and kept high or your inverter will turn off or your charge controller may go into a different charging mode or even turn off also.
A battery will keep the voltage high until it is near empty, a capacitor loses that voltage very fast under load.
You can not expect a capacitor or battery to store more power, than the solar panels will deliver.......you still need enough solar panels to supply enough power for your needs.
To start a car, the starter requires only a couple of watts......not much at all.
But you are talking about thousands of watts with your solar applications......Will not happen.......
A capacitor merely stores enough electricity for a short burst of electricity and is not good for storing electricity. Capacitors were designed to give motors like AC units a jump start or a burst of electricity to get the motor moving faster. That's how I understand it anyhow.
You're a bit out to lunch - capacitors have a higher power density, but far less in terms of energy density.
Also, to say a starter requires only a couple of watts is complete nonsense. You might want to do some reading on the difference between power and energy (hint, energy is power multiplied by time). So while a starter takes a small number of Watt-Hours, it pulls a boatload of watts (i.e. 200 'cranking' amps * 12V = 2400W - say it cranks for 3 seconds, you're using 2 Watt-Hours).
Just some helpful hints ;)
J & B Homeliving and he built a soln1 2000... happened
That was interesting. I might add that the ignition switch turns off the electrical accessories such as headlights and air conditioner fan motors during engine start. So having them on or off makes little difference when starting the car using the boost pack.
Vetty nice very impressed. I think i'll build one.
Interesting vid. Thanks. How long does it take to charge the caps from flat to full using your solar panel? And what are the specs of that panel? Also, how much to these giant caps cost at regular electronic supply companies. I'd be surprised if they sell for just a few bucks apiece. Still, anything providing off-mains power and reducing lead in the environment has got to be helpful.
Great video! Can you tell me exactly where you purchased them please.
Very well done! Thanks for posting.
It’s been 11 years since I have installed my super caps. Still running strong 💪
The cheapest I found these capacitors was $65 each, to make the pack you describe in this video would cost more than buying actual batteries.Now unless weight is of utmost importance, price would dictate that its not really a good value for the amount of power you can store.
I just wonder how much of the stuff you see in how to do it videos came from or walked out of some employers inventory.
The people who make these videos may have something that works .. but ... so often the actual cost is so high that unless your need was dire and the real product was not obtainable, no one with any sense would do it.
John Henry Reaves paranoid schizo
not to mention if u have a older car with older wiring ur might find it causes alot of problems, and I can only imagine its not gonna last 1/2 as long as a good battery that u spent $60 more than what he's saying he's spent. u found something that works if u have nothing else, I doubt its superior.
Danielle Pevec Millions of cycles? really... is that under the temperature that most car batterys sustain?
theres a insane mark up on capacitors because they are normally used in industries that gov is all up in stilling money from climate change. anyway u need to know someone that has a business account in heating or a/c then you can find them for real cheap. market up is like 1000%. this vid may be cool but not pracatible anyway
Christina Ibarra It is not BS these caps were literally $5-6 each around the time this video was being made as literally thousands of used caps were dumped onto surplus sites but people bought them up pretty quickly when they realized they were available.
Yes, I am kicking myself that I did not buy a lot more back when they were $6 each. At the time I had no idea what I would even use them for.
I'm in Washington state....
+Bob White So?
+kuhrd I believe it works as you say but the only issue i can see is extra wear on your contactor that starts the car. The contactor is only rated for so many amps start and stop... now you are many 100s of times that number. You will eventually pit or weld shut your contactor and it wont let you start the car...
The voltage remains the same so you are not sourcing any more amps from the capacitor bank than you are from a properly sized battery. The internal resistance of the starter an cables remains the same.
Very good idea. Congratulation to you.
Thank you for a beautiful creative idea. I bought some Maxwell ultracaps to experiment with. You are to be commended for piqueing our thinking. I am working to get off grid with Los Angeles Dpt of H20 & Power with their tier1, tier 2, tier 3 billing system - use more than a certain amount of power u pay more!
Size and source for capacitors, please?
Large capacity caps like this will give you a very high rate of amps, but have a very small amount of reserve capacity. This means any of the following scenarios will render you screwed: Engine is hard to start and needs to be cranked, alternator fails while driving, you leave your lights on for more than a couple minutes, etc etc. A lead acid battery has an infinitely larger reserve capacity, and can work through these events.
Well...not infinitely.
Not really infinite.
What are you gonna do walk your car home off the starter? The scenarios you described are pretty much ones where you'd end up stranded anyway, or something else is going on with the car, in reference to the hard to start part of it.
I don't leave my lights on without the car running.
Can there be a capacitor battery combination?
parallel them with a deep cycle battery for best results, RAW POWER plus long reserve time...
That was very impressive timing that you ran the Drill bench with just 6 of those Black monsters juice. I am very and i say it again, immensely impressed what you have achieved there back in 2012. Today is 2019, you should be running your Drill bench with free energy......Serious I am.
Nice work on this.
$6.00 each? Most are $50 each or more.
350F are 10$ ea now days used
There's this thing called buying in bulk.
Can someone tell where you buy these caps for $6? I only see them for $35 each
+galaxybeing1 they arnt 6 dollars a surplus of these capacitors went down in price and people bought them dry.
Awesome! Please shoot a video. I would love to see your setup. I also just started testing a small 1.5 watt dash solar panel with my setup. It seem to have merit over the hybrid system.
Great. A a ham radio operator I know some of our equipment uses small capacitors to maintain voltage for memory. I'm thanking this would be the way to go for EV's. Less weight and fast charge time. Keep up the good work.. WA4BEW Bill
let me know where those capacitors sell for $6 each
I got a bunch of those caps too. Was going to use them for solar exterior lighting system, but car battery seems a much better idea.
I don't know why TH-cam always sends me video recommendations as old as this one, but as long as they are worth viewing it's okay with me. That being said, those are the largest capacitors I have seen since I was on active duty in the Marine Corps back in 1984-1987.
I wasn't paying attention to the depth my needlenose pliers were sinking into the silicone potting compound around a terminal board from an anticollision light flasher system and accidentally crossed the power and ground terminals. The capacitors hold a minimum fifty thousand volt charge they dump all at once, take mere seconds to get recharged, and dump again in a continuously repeating cycle as long as the pilot has activated the anticollision lights. I was rewarded for my lackadaisical demeanor with a huge and powerful blast of current painfully wriggling through my muscles making it impossible for me to let go of the pliers.
Thankfully it was unable to recharge itself and kick my ass some more! The pliers were history after they melted clear down to the intersection of the two halves, which resulted in a written reprimand being placed in my file. I couldn't care less about the paperwork in my file being held against me; I was glad I still had all my fingers and toes!
They have 3400F 3.2Vdc available now, but $$$
Nice vid, question: can the alternator take so much instantaneous current passing to charge the pack???
+Cham Raf It should not be an issue, if it is, the voltage regulator part of the alternator was poorly designed. The 'voltage regulator' limits the output of the alternator by limiting power to the 'field' winding... this should be designed to run happily enough at a %100 duty cycle. The caps on the other hand :O Charging them in series is asking for trouble... if any one of them has a slightly lower capacitance it may end up over being over charged repeatedly.
+Ben Lucas Tell us more.. as I am seriously looking to do this..I know the alternators have seriously dumb regulators in them.. they are often time based rather than statistical based. menaing they cut out after a period of time rather than if the battery is fully charged.so they go from bulk charge to trickle charge in 15mins. so if you include a BMS with these caps.will that solve the problem?
+bicanoo_magic
Right idea about using a bms, i've seen many variations on ebay etc designed specifically for larger supercaps.
An automotive charging system is very basic. They do time based stuff on newer cars but anything say pre 2010 mostly has an extremely dumb voltage regulator style... As much current to field coil as needed (up to its maximum rating) to try and maintain 14.6 volts to the battery/system at all times it is running.
Issues with using these first. Very low capacity compared to pretty much any 'battery'... Just did some math on it, and long story short, If charged to 14.6v after the equivalent of about 0.56Ah of current draw the voltage will be down to 10v. I know my van wouldn't have a chance of starting with the electro/hydraulic gearbox thingy it has and this setup even fully charged.
High leakage compared to pretty much any battery... charged to 14v down to 12 in a day or 2... and that's not hooked up to security system of car etc.
Maybe for a race car in tandem with small AGM or lipo for some actual storage capacity. Capacitor bank would drain almost instantly with large fuel pumps etc running and engine stalled. It may allow you to run a smaller total weight by reducing size of battery more than the weight of adding the super caps and still having enough CCA (cold cranking amps, lol, old school automotive term) to turn over engine, but i highly doubt it. By the time you add weight of super cap bank to the battery you could just have a larger battery that would be able to turn over the engine and have far more capacity :P
Shouldn't be a problem, alternators have internal devices that limit charging current.
Wow, great stuff! I have a question... I'm interested in implementing this system into my boat..? - Quick backstory/info - My boat has a 150hp 6cyl outboard motor which requires a 12v cranking battery. My trolling motor has a 36v battery bank (3-marine batteries). So in total, I have 4 batteries on the boat which is a lot of weight. What is worse is that they are all on the stern of the boat -- another story entirely - but basically when the boat is at rest the stern is extremely low in the water and the bow up in the sky. I am planning on moving the 36v battery bank forward to the driver's seat (2/3rds forward) which I know, leverage wise, will reduce a lot of weight on the stern
Now here's where this supercapacitor comes into play, I'd like to completely eliminate the cranking battery in the back of the boat and replace it with one of these supercapacitor banks. Then, I would like to use a 36v to 12v (20amp output) voltage reducer (designed for golf carts) in order to create a hybrid system that can recharge the capacitors should the motor not start immediately.
Will this work?..ish?
Will the alternator damage my voltage reducer (which I assume is not designed for 16v being pushed back into it...)? if so, Is there some type of Diode system that would allow the outboard to charge the capacitor bank but not allow it to back feed into the voltage reducer?
I have absolutely no concern about the capacitor bank going "dry" and leaving me stranded as the 36v trolling motor system can power my boat for days and days on end
What other concerns might y'all have? Would I need a BMS to protect my outboard alternator (I don't know what a BMS is sorry for my ignorance).
Thanks in advance for any input!!!
I know capacitors don't store energy over long periods of time well so how would these preform over lets say 7 Days of non use. Would they still start the car?
That depends entirely upon the capacitor. Had an old tv, sat for 6 yrs without being plugged in and the capacitors still had a charge.
the trick is to add a small battery that just keeps the caps topped up
@Shanee Fucking awesome response!!!
codergopher - No they didn't - you are mistaken.
7 days isn't a problem for this kind of setup. Depending on your capacitors and how much your car drains when in idle, it can stay charged from 1 to 3 months.
you did a hell of a job! yeah save alot of money , you do nice work man :)
A suggestion: if you're going to regularly charge a supercap with a solar panel, get a peak power tracker. Most charge controllers are just voltage-actuated switches that connect the panel to the battery until it reaches a certain voltage, then they open. Solar panels are near-constant current sources, so as the load voltage drops the current barely rises and you get proportionately less power. A peak power tracker operates the panel at whatever voltage produces the most power independent of the load voltage. So even if the capacitor is near zero volts, where direct connection of the panel would produce little power, the panel could still operate at 12V or wherever it produces peak power. Most "12V" panels actually peak around 16 or 17V (higher voltages in colder temperatures) so you could get more power even when the capacitor is fully charged. And it will charge *MUCH* faster if you start with the capacitor completely drained.
It's been 6 years since this was posted, updates?
He's off building crystal batteries.
at the current prices you could get a lithium dry cell battery and be better then a super cap batt or traditional battery .. also the newer graphine super caps haqve a much better potential to make this happen.. the graphine caps store power better over long periods and futher increase max capacity vs size and weight
@@Y2daT420 i know one youtubber who built a hybrid lithium + caps battery. But there are still problems with the cold outside. Quick self discharge plus losing capacity due to cold air. So such batteries also needs some kind thermobox.
@@Y2daT420 Nada. You can get 3.2v supercaps now so only 5 in series would be needed. Supercaps do not have more power, just more instant current releasing than a car battery. Caps have internal discharging so long storage will deplete them.
@@jbnrusnya_should_be_punished No. Just cold air puts more strain on the starter as its harder to spin the engine over. Run Synthetic oil!
Each ultra capacitor are $69.00 USD not $6 as you stated. 6 x $69.00 = $414.00 for your car battery. The ultra capacitor can hold a maximum that I found on Ebay is 3000 farad at 2.7 V each cell with a mass of 405 grams each ultra capacitor. Just the ultra capacitor would make the mass at 2.430 kg the great thing about these ultra capacitor is 1000000 charging cycles. It more than cost of a car battery but depending on uses it could be a good option.
I'm runnin a 12v20ah AGM cost me $40 on Egay, they also have a 35ah model for 65
TheBikemaster94 enough CA to start a small car?
No Name yeah I'm runnin the 20ah on my 1.5l and it always starts the first time , had it since October. If you leave the radio on it will struggle a bit. I'd go with the 35ah just to be safe it's about 1/2 as much as a basic walmart battery. People laugh when they see a tiny battery but AGM is more advanced than lead Acid. It doesn't leak, it resists vibration, and it's got more energy than a lead acid of the same size.

I just wanted to point out that in the second part of the video, you didn't actually need an inverter because many corded power tools will run off of straight DC as well, but you would want to increase the voltage up to at least 80 volts or so. So this is a great idea to use these supercaps in a solar powered shop. You can find 14v supercapacitors too and put eight or nine of those in series to get closer to the voltage the power tools were designed for. You don't want to over-volt motors though, so best to keep it up to but not over 120v, _unless_ you really know what you're doing and compensate with extra cooling.
You have a way of charging 80volts?. Each cap is only rated to 2.5 to 3.2vdc. Over voltage will destroy the caps
Thx for the response. I get the burst idea now - thx.
Your car sounds like a microwave oven 😆
In the 50 years I've been driving I've had generators or alternators fail while on the highway. Automotive batteries today are rated in cold cranking amperes and reserve power minutes or how long you can drive the car if the alternator fails. Usually you can drive at least an hour maybe more in daytime without lights and if you'll leave off the AC/Heater blower just on the battery if the alternator fails. I'm afraid this type of arrangement will leave you sitting on the highway before you make the next exit...
Howard, I agree with you 100%
Howard Bee Maybe the battery can be kept as a reserve with an alarm to say something is wrong?
***** Vehicles are already equipped with an alternator warning light or a system voltage meter if the alternator fails. If I need to keep the battery for reserve power capacity wouldn't that negate the need for the capacitor bank?
Somewhat, but at the same time if you make a hybrid of the two, you might be able to choose how much of the benefit from each one you want. A small battery might be a nice way to act as a safety device which can get you to the next exit. If the car uses it rarely, rather than a battery that likes deep cycles, a long term storage solution like lithium might become feasible where the cost to power the vehicle the entire time would have created a huge expensive battery before. Maybe. It takes more expertise than I have but if they are in parallel, the battery would be the vehicle's version of an emergency adrenaline rush...too expensive to use all the time but great in an emergency. :)
***** its great that you are trying to think, but you are failing miserably at it. lets put things in perspective. replacing your battery with a super cap set up saves 15LBS, studies show REMOVING 100LBS = 1% FUEL ECONOMY INCREASE... so even the set up the guy had above gives him almost nothing in return and puts him way more at risk of being stranded. To do this hybread you suggest means a battery half the size of the normal one and a cap which already takes up the full size of the battery... now you probably have more weight than the original battery and no where to put the smaller battery, you also need pretty thick cables to go to that smaller battery, which again adds weight and because its a smaller battery its still far more likely to leave u stranded. there is no benefit to this. internal combustion engines dont need an adrenaline rush, wishing to make it possible breaks a system that works well currently.... they require a decently constant supply of moderate amperage which the lead acid they come with is great for. yes you could argue that using the caps and saving 15lbs over every car in the world may be significant... but due to the fuel hungry nature of a tow truck you would quickly see that advantage disappear even in the fractional fictional reality's you think it exists.
You can use this for years.
Congratulations
one use i can see this system having is in conjunction with a leisure battery, which doesn't like to give out its power too quickly. so you get the cold cranking amps, of a car battery with the capacity to deep cycle without the vulnerablity to damage from excessive drawdown
I would really use plastic like sheet HDPE instead of using wood , wood can conduct electricity
stupid it can't as the resistance is too high to conduct 12VDC.. He could increase the resistance by putting silicone spacers or gasket maker on the posts
Well than how come we don't make wood wires
The only use I see from this is for high-performance and racing applications, where weight savings are of utmost importance. Have you reached out to any amateur racers in your area to see if they're game?
I would like to try this on my dragster, for the space saving AND weight savings!!!
@@cmsracing Great idea.
That's great pal!
Thank for the idea sounds like a great for portable jump box I like how fast they charge up I just wonder how long does a cold or extreme hot weather
its charging back up to 14 volts because ur actually testing the alternator there..while the car is running.
I agree, I have been a mechanic for over 30 years and while I am not instructed in the use of capacitors etc. I agree that you are getting the feedback through the positive wire showing the charging voltage of the cars alternator. However I was interested in perfecting your invention to use as one of those jump off boxes, for example; I have a 50cc moped with a super small battery compartment that won't allow a large enough battery so it has to be jumped off all the time and a small capacitor invention such as yours would do the trick and still be small enough to fit in the seat so I am very interested in where to get the parts at the most reasonable prices and how to safely build and use it.
@@josephsmith7026 Supercaps will charge up as fast as you can supply them unlike a car battery. The limit is the alternator. Its not like a battery. So, if its 14v, its charged already! Note that a lead acid battery has more overall power - but its over time as batteries have high internal resistance. Caps have huge current draw and huge release of energy as it has super low internal resistance, but does not have as much power over time. But, millions of cycling and very light weight make these ideal. These won't power an electric motorbike but for a gas bike, but note the motorcycle has a very low output alternator so will take longer to recharge and may damage the alternator without a limiting resistor. Ebay is your source. If 12v then 6 caps in series.
where did you get these for 6 bucks I can only find 6 of them on ebay for 300 +
***** It's good to point out Royce findings as I do search online myself and did not seem to find the $6 Maxwell Boostcap Supercapacitor as mentioned in this video... Would +lasersaber be so kind to share with us so we can build one ourselves... Pleeaaasee... ^_^ a quintillion thanks to you !!
Just did a quick Google search and found them for $6 apiece here: www.mouser.com/Search/ProductDetail.aspx?qs=JV7lzlMm3yJDkhnJz3nobw%3d%3d
the ones you link to are only 50F each. you would need 312 of them to match the energy capacity of the ones in the video... $1291.68 before shipping, not to mention the huge footprint and work required to get something like that wired up.
Ah, good catch. I missed that.
Royce Ardery people bought them too quickly when they found out hiw cheap they were
I thought about that too. I didn't know about the damage, but I did consider capacity.
When you connect anything in series, you decrease the voltage across each element. In this case, 14V divided by 6 capacitors equals 2.3V each. You also divide the capacitance by 6, so it's only a few hundred farads as opposed to a couple thousand. That's still a lot of capacitance though.
6$ a piece?! D: I want to live in america. in germany, i have to pay 30-60€ ( 40-70$) for it
Socialism is Anti-Social in fact that's the point. Your money becomes OMP-FR Other Peoples Money at a Faster Rate
Most super caps have a max temperature rating of 70c. If it is operating under these conditions, normally it has about 1000 hours lifetime. I would imagine that under the hood, the temperature would easily reach that.
Some cars have the battery in the trunk so i don't see an issue here...
cab3 "some" arnt that way so you cant see how it would be a problem? have you tried not sucking at critical thinking?
good for them. what about the ones that arent in the trunk, ya idjit?
And car batteries should NOT be operated at 80F or higher since it will shorten their life cycle enormously to a point that it will destroy them.
Car batteries are cheaper ........
ok now I'm impressed :)
So many negative comments, I think this is a great idea. If you had to pay what we pay for fuel in the UK, every pound in weight saved is a big bonus. Anything that deprives rip off oil companies of money is worth doing.
Amazing you spend so much time messing with capacitors and boost packs but pay someone to change the oil !!!
Funny!
I work on my car all the time but sometimes, on a hot summer day or a cold winter evening, it doesn't hurt to have someone do it for you.
he excels at electronics, not a mechanic
Because he is an electrician and not a mechanic...
Please make a video on how to make one of these, or at least put a schematic on your webstite! Thanx in advance!
It's a gimmick. Look it up. It's just a capacitor bank, that's why this isn't used widely. Look up what a capacitor does. No such thing as a "boost pack" and the caps are 80 dollars each. You can get a battery that will do way more for 70 bucks. This guy just uses a tool for 16 seconds, how much work could you really do with that kind of time???? Near zero.
Ok?
It's just some super capacitors wired in parallel: this is not a new idea.
Thanks
What battery cost $70? 40AH?
For winter, or generally wet/humid weather, loose the wood and do cover all your leads in there! There is a stuff called PlastiDip, you may try that.
Also, you could combine a regulad lead battery (maybe a smaller one) plus your boost pack. Battery for capacity, booster for starting amps.
Brilliant well done 👍
I want to see the AC , headlights , stereo on for 20 minutes and see how much voltage it drops cuz he seems that you were in a rush to turn the car back ON after having your headlights ,AC on cuz the voltage was dropping very fast. MANY MOST NEW CARS THESE DAYS AFTER USING THEIR HEADLIGHTS REMAIN ON FOR ABOUT 30 SECONDS OR SO .
So I would like to see if can handle for more than 30 seconds or a minute before I go out and buy myself one of these or make one for myself .
Hey, no rational person doesn't know that these gadgets will not let you run the headlights for an hour or two after you shut off the engine. But the important point is that with a "backup" system (perhaps a Lithium Ion cell pack), this could save weight AND give better capability.
Its quick discharge
You too lazy to turn them off before starting? You will have a lot more than 30sec with just auto headlights.
So what happens in the long term? How come car batteries aren't made this way?
+mychannel Little capacity and high cost. With 2600F capacity (I don't know exactly how much it is) at 14V it is only 36400 As = 10Ah, while it costs about $200 in total. Considering that modern car batteries hav about 60-120Ah, this is too little for a general use in our society.
Another side effect is the high leakage. You can't place your car in the wilderness for some weeks as it won't start again.
***** You're right.
And yeah, the voltage curve makes the different, although I would be interested on how low the voltage can drop until a car won't start again.
Different devices shut down when they reach a specific voltage, but how about starters?
+mychannel Also because of capitalism. Keep the people coming back for more because they don't last forever unlike capacitors.

Bone Drone Fucking capitalists again!! Damn them!
***** I don't think you see the entire picture. Again.
Batteries= $+$+$+$+$+$+$+$+$+$+$+$+$+$+$

Onto energy density how about this. You saw a set of capacitors similarly sized to the battery being replaced and it weighed 1/5 what the battery did. So therefore is size for size a fair comparison? How about weight for weight?
So many questions that can be simply answered by doing! You could get an amplifier install kit with 4ga wires and install the boost pack in the trunk in a plastic battery box. This would eliminate the engine heat problem and the safety concerns. Many newer cars have the battery in the trunk already. I would love to see this implemented on a Prius with flexible solar PV panels on hood and roof!
It's best to use them in conjunction with a battery so when your battery drops to low it charges it when starting ignition
Lasersaber, can you link us with where you bought the boost caps @ $6.00?
These capacitors last much longer than batteries
Bruce G you clearly have no fucking clue about electrical systems
Hey Puke - How about 40 years experience
You're sad, Kook. Do you really think a battery would last longer than a cap.?
1,000,000 cycles. A lifetime
IN ADDITION, you can put a softer spring into the starter solenoid, to minimize the energy needed by the starter.
one of the benefits of the lead-acid battery is the power density. if you lose an alternator while traveling, you will be able to run your engine for quite some time on the battery reserve. if this happens, you should shut off all accessories, like A/C, lights if not needed, radio, etc. this depends on the condition of the battery. but, there are uses for such a light weight capacitor storage unit. good job. great to see the innovation.
your battery needs electrolyte. plates have to be covered.
I partially agree on that, but still, once the battery goes depleted it can no longer be recharged. I personally tried pouring the sulphurous acid into a motorcycle battery and all I got was power for a short period of time, no effect for longer time if the battery's already depleted.

You make it seem so easy to charge. In another video "fun with ultracapacitors," the guy needed 20 minutes at 5 amps to charge. What gives? I know the alternator can provide plenty of amps, but a solar panel?
The guy in the other video is using a bench top power supply. The alternator in your car is generally capable of producing at least 60a (at 14.4v), my miata for instance. My truck's alternator was capable of producing 95a stock and I replaced that alternator with a 130a unit (to help power a stereo and wench). Also, this video has the capacitors wired in series, meaning the voltage capacity is increased without increasing the charge capacity. In the other video he wired the capacitors in parallel, increasing the charge capacity while the votlage remained the same as a single capacitor.

But my post was about a solar panel. How big of a solar panel would you need to charge it at that power level?
ThingsDemystified Sorry I misread your question.
This could charge a 350F capacitor in around 23min.

Brilliant, thank you!!
Ideal for a enduro bike that has a kick start or roll start capability as it is super light.
Thank goodness its about time
i dont believe he bought these for $6 each
I believe it. Buy from alibaba, it was really cheap.
HOOTS C wish got em for the low low
He got them from a surplus store - Mouser I believe. Now you have to pay full price.
