- Here is the final Install video for this project. The system works perfectly without any problems. Basically it's just a 10Ah LiFePo4 battery, 240F 15V rated supercap array, with a 0.1Ohm 25W resistor in between them to limit the current to the battery. This system had no problems starting my 2013 Kia Soul even at 2'F.

If you could integrate supercapacitors to help the battery of a hybrid car like the Prius or Insight it would be brilliant. All respect for all you do!
you could use a dc-dc converter to run the capacitors up to 15v, and use a larger ohm resister back to the battery. though you have more than enough amps in the capacitors, you're not taking advantage of the high voltage capacity. I'm using a 50W solar panel mounted to the hood to keep my capacitors topped at 15.5V (using a dc-dc converter). I don't currently have a battery hooked to it.
I added a lifepo4 3ah (hjtx7l-fp) battery so I can start my car at night or in the early morning. works perfectly. I have a .5 ohm resister and a 5 amp self resetting breaker inline to protect the tiny battery. Works GREAT!! the battery was $43 on aliexpress
my parts list: all from aliexpress
2 banks of super caps 500f ~16.2v on balance boards - $38 each
50watt solar panel - (ebay) $50
hjtx7l-fp Lifepo4 battery - $43
5 amp breaker $2.63
.5ohm 50w resister $1.42
Very reasonable for something that should last at least 10 years in Alabama weather
Wondering if you are willing to put together an entire kit ( in your spare time ) and sell them ?
Interested in the rough total cost (unit with display ). Thanks
Nice! I had this idea and searched for someone that already perfected it. How long do you think this would extend the life of a normal car battery? (Just the caps added to a battery)
What is the size of your hinged plastic enclosure as the Amazon link is no longer good? Thanks...
Do you wire the current limiting resistor directly in series from the positive battery post to the positive side of the super cap?
Hey is there a BMS? Can you use a BMS instead of the resistor?
Do you think this will work even if I add a car audio amplifier ? 700watts rms I have used lipo batteries to jump start but they tend to get puff off if left for more than the requiered seconds . And they been losing cc rating that’s after I discover that the charging system they had on their case had no monitor( balancing circuit it has just outputting 4.2v to each no mater if it was balance or not ) and that messed up the whole pack . I have install a 1 farad cap 12-16 v but I don’t think that helps it actually reduces the voltage going into the amp which is close to amp and for this car electrical system really doesn’t stress much on outputting 13-14v but cap shows 10-11.8volts .
If it is possible for you, kindly let us to have the circuit diagram of the completed project please
It's been 6 month! Haha
I've got a 2004 Cummins Ram, what would you recommend for Supercaps and battery?
Thanks man! I share this playlist all the time.
Yeah, we got an update coming?
Will you help us doing the same for electric car which has 30 kw motor and it draws max 280 amp, will you be able to design it, we will buy supercapacitor maxwell with balancing circuit but rest i have no idea as i am a mechanical engineer..
Please make it with Makita power tool batteries 18 volt that I can just slide my batteries in and go they are 18 volt and come in 6 amp hour battery packs. you could also do this with other size batteries and power tool batteries. think about how much simpler that would make it to remove and install batteries if all you have to do is slide it in /out take it in the house and charge it in 35 mins. you could always have your batteries in doors away from inclimate weather. I honestly do not know why they have not gone with this option before a tool less battery.
Ok, ill say it: SMART guy, and a ZZ Top look-Like Fan?
Awesome, Awesome, Awesome work man, you sort out all my worries when I first saw people using super cap to replace car battery on TH-cam.
So very cool..and man does that engine just jump to life! Awesome...I really need to build me one of those...hate having to replace batteries every 3-4 years down here in Texas
I came across part 10 of this amazing series only this morning and have been glued to the monitor ever since, watching parts 1, 2, 3, etc :) Seems to me that the same principles could be applied to regenerative breaking in EV's, could it not? I found the reasoning behind replacing the 0.5 Ohm resistor with a 0.1 Ohm resistor a bit too brief. Could you please elaborate why the replacement worked better? Thanks for all the inspiring insights and demos!
I like it and am going to build one. And I DO NEED ALL THE EXTRA STUFF. Great job.
Hi, I would like to use your system in a ham radio application for the emmergency community. How long will the system last if say it was running a load of 55 to 100w, such as a car headlamp without being recharged by the alternator. From this information I can extrapolate how viable it would work in my enviorment. It would save me hauling around a heavy leadacid battery. Thank you you are doing a great job.
24 volt would be better option as you can run solar, power tools, and household appliances on it..... its form factor is small and lightweight enough to use in handheld power tools and its stackable to at every voltage to 600 volts ...... 24 / 48 / 72 / 96 / 120 / 240
ordering the stuff to see if i can get away with 6x (2.7v) 500F super caps in a ~15v array (so ~80F), 0.1ohm 50wat power resistor, and 7aH 12v lifepo4. 4 banger, early 2000's civic. i figure if it doesnt work ill just push start it lol. would like to see if I can get it to cost a third what the equivalent lead acid battery costs.... and lower internal resistance of the supercaps should slightly nudge gas mileage on hwy trips i think. got a mini polymer "ammo can" to put everything in. the ones that come with the gasket seal since keeping caps dry seems to be the magic to longevity. going to make a copper busbar and put nailpolish on it or something.... dont like heatshrink as much
I think I would still want a low power cutoff for the battery for theoretically if I gave unit to someone else and they let their car sit for too long with parasitic draw.
Genius
Great
will THIS scale up to 330Volts DC? Dual 60KW motor
it KILLS NMIH pretty quickly replacement time frame is every 10-15 years
hi can you send me a link wear i can get the display you got? lead me know if you can help. Nice Video continue the Grade Job thank you
Did you have any weight savings? I have a high CCA requirement for rotaries, however weight the reduction point for me.
I would say at least 50% lighter then the lead acid battery it replaced. Should be easy to do on a rotary as I don't think you need as much cranking amps, but I could be wrong.
@@madelectronengineering Thanks! I'm starting my project soon. The rated CCA required is 700.
What is the CCA rating of the LiFePO4 battery? I'll guess a low of 250 CCA and a high of 450 CCA. I really like your instrumentation in the car!
The LiFePo4 battery is a deep cycle battery. It does not have a CCA rating, but I would venture a guess and say maybe 50CCA.....
The two strings of supercaps I use are rated at 700Amps to -40'F if that helps.
The LiFePO4 battery just keeps the supercaps topped off while the engine is not running, it keeps the electronics alive and runs the low current draw lights and stuff...the REAL power of that setup is the HUNDREDS of amps of power that the supercaps can dump in cold and hot weather, and they can do it over and over and over and over and over again for hundreds of thousands of cycles vs a few thousand or so for lead acid...
Thank you brian!
I've watched your whole series on this new battery technology and absolutely loved it! So much so that I subscribed to your channel. Of course now I would love to build my own. I just found out that you also live in Delaware, like me. I live in Sussex county, a small town called Milton. Where are you? Did you ever put links on your channel as to where I can buy the product needed to build my own battery? If not, can you, so that it saves some steps and helps the cause to save the environment by not still using lead and also saving weight on my 1999 Honda crv. Trying to eliminate as much weight to get better MPG's. Thanks!
Well done! Have you seen the Schumacher Super Cap device being sold as a Jump Starter for cars? It is connected to the low battery or another battery to quickly charge the Super Caps so it can then be used to start the car. It is quite clever. Here is a link: www.amazon.com/gp/product/B01MZZD2YB
Your design takes it to the next level. Super Capacitors for the dumping lots of CCA in extreme temperatures and a Lithium Ion for the deep cycle parasitic devices and keeping the Super Caps topped off. This will be the next revolution in vehicle batteries! Hopefully you are able to patent this process.
Would this work with the cap pack for starting, and a deep cycle battery for accessories? For example in a van the capacitor bank under the hood with a 110ahr battery inside the cab. Using the battery for radio, inverter, ect., while the engine is off. And using the caps to start the vehicle on their own.
Hi,
Thanks for sharing. I am planning on replacing the lead acid batteries in all three of our vehicles with the same hybrid battery.
Only additions I might do is two terminals connected to the capacitors to allow jump starting. And a small solar panel to keep the battery topped up as I often need to leave a vehicle parked for a full week.
It only takes 2 seconds to start a car. The mah doesn't need to be 2
hours; Soo the configuration of the cell itself is not efficient for the
purpose of a car starter battery.(It could be much smaller lighter and
cheaper if it were designed for that purpose )
For lights etc., long lasting lion batteries would be most efficient.
What would you recommend for 2.5 L Diesel engine for capacitor.
And temperatures in the summer? There are several cars that has cooking battery liquid and batteri dies instant and they fixed it with a heatshield and a fan?
Get a weather resistant strap or something, that so call bungee thing will crap out.
Could a version of this be used to replace the battery in a computer UPS? Most local outages are extremely brief, second. Be great to have supercaps take that load and extend battery life. A bit different as eventually battery needs to kick in
Not so much. Caps allows for a smaller battery in a car when it comes to starting. Look up Li 12 volt battery for UPS.
Coming up on a 1 year review :)
Just posted it last Friday.
Would you change anything for a high-compression V8, do you think a single bank of 5x3000F be enough?
That would work. Pay attention to the max voltage of those 3000F caps though. If they aren’t 3V but 2.7V you’ll need 6 of them.
I think you can buy ready to use packs on AliExpress and EBay. Don’t forget the (large but low value)resistor between the pack and the battery if you want to relieve your battery from strain.
v8 SUV and pickup trucks have a 15.3 volt Power Output. when using tow mode. so you will need more then just 5 other wise you will pop them
I see a long term issue that could develop and result in unbalanced charging between the super capacitor and the rechargeable battery. The super capacitor has very low internal resistance and gets charged very quickly to the car's max charging voltage (approx. 14.4v). You can see in the video it didn't take more than maybe 10 seconds for that to happen. Meanwhile, the internal resistance of any rechargeable battery is significantly higher than that of the super caps. I don't know the exact details of how a car's charging system work on a typical lead acid battery but I highly suspect that once the super caps maxxed out at 14.4v the car will stop charging any further and the "back up" rechargeable battery won't ever get to reach its full charge. In may even incrementally get depleted further and further as time goes on. It's like trying to charge two batteries in parallel and each has very different capacity and internal resistance values. How can you really charge each one to its full capacity while in parallel configuration is a real challenge and the key to making this supercap + battery combination work for as long as possible. Remember these super caps are supposed to be good for at least 10 years ...
sr. supercapacitor take any voltage (that's why you have to limited it) and deliver a huge current wherever it will find a way out with lower voltage up to equal his own voltage. amperes doesn't hurt it will take what it's needed according to the voltage /(battery = supercapacitor) note: never attempted to hook up a uncharged supercap below 11 volts for a 12 volts battery you may used a 12 volts light( light will go off but steel keep charging ) to limit the current to the capacitor until it reached the 11 volts.
