Hybrid Supercapacitor Car Battery 2023 Build

[@mkssnwbrd]

I think capacitors are the future of EVs and battery replacement in general. I'm excited to see people using them this way.

[@RaymondLohengrin]

Years ago (about seven years ago) I installed a military grade Maxwell Super Cap pack on my Suzuki Vitara 2.0. I was able to run it all over town for a month using just the super cap with no batteries. I had a booster with me just in case but the super cap could maintain its charge over night and could start the car the next morning. This was just a test so I had to be very careful not to leave the radio on or anything that could drain the caps! I then added an RC small battery to keep it charged and later a small 12 volts dry cell alarm battery. I am still running this super cap and just I just drove today over sixty miles. I purchased a second cap bank but is a cheaper brand and it drains really fast on its own so I have used it for years on my lawnmower, I just jump it, do the work and I don't have to keep buying batteries every summer!

[@jumpAmonkey]

Gotta love it when Jethro starts tinkering. Even better when they start binding things together with tape.

[@chrisw1462]

Don't use electrical tape on that positive jumper - use Rubber Tape! The package will say 'self fusing silicone' or 'self vulcanizing', and it's Not Sticky - except to itself. Much better insulation and it'll take more abuse than most electrical tape. Heat will eventually make regular electrical tape brittle and destroy the adhesive.

[@SheikhN-bible-syndrome]

Yep they have my favorite one at Walmart its got a blue backing that peals off and its nice and thick and melts together and makes a nice solid rubber cover to whatever you wrap it in

[@haydenc2742]

Duuuude! Pretty much a drop in ready to rock and roll setup! I would bet it would be able to crank even V6's without issue! Payday...I'm going for it! Thanks for this man! Keep em coming!!!!

[@CarAudioEnthusiasts]

itll crank a semi truck with no issue, thats how theyre wired in a truck, the cap does ALL the starting

[@ericcaldwell3584]

Looking forward to seeing the updates on this project! Thank you for the tour and the info!!

[@Brandon_Neil]

6:10, wow a voltage drop to 13v. I have the same tester and my van with a 160 amp alt drops to 12.4v at idle.. definitely need one of these.

[@mr.18s73]

Thank you for video I wasn’t sure if cap was under hood safe do to heat? But I guess it’s safe especially for my application. My vehicle is for bass 😂 .. I have 2 super caps running together with a blue top agm under the hood and a 48ah headways lithium bank in the back close to my amps . But I’m getting rid of the blue agm and replacing it with a ioxus super cap and just run the lithium bank in the bank that will power all three super caps .. I’m going to run 6- 12s subwoofers 😂 boom boom 😂

[@yougod7253]

Brilliant idea I gonna try that.

[@850CANE]

I run two of these ultra caps with a 96 amp hour headway and it's phenomenal. 8K sub amp and I hold good voltage I stay around 14 volts​@@yougod7253

[@quagmire94]

.10 is alot for sleep mode, you definitely have a relay issue most cars draw .03 ~ ish mah thats probably why you are chewing through batteries id' check your Security relay on my jeep the alarm relay was on 24/7 even while started. so i just pulled that relay and i stopped having battery issues.

[@Montgomerygolfgator]

My 15 Soul+ doesn't eat batteries like this (although, your wife's appeara to be a Soul! Given the headlights, which also means she probably has the subwoofer and amp) You might consider testing each circuit for a ground fault, as well as check the alternator. Mine has had 2 batteries over it's life, and I know the previous owner had it somehow starting with an extremely loose connection (like, the nut was flick-spinable) and it was causing a traction control fault light of all things as the only symptom. You've given me something to think about when this one eventually dies for sure!

[@RadioTrefoil]

Very interesting series, I've been binging all the videos. I am wondering whether you are concerned about degradation from high temperatures in the engine bay? Considering LiFePO4 seems to be rather sensitive to temps over 60C. I understand some companies specifically sell more expensive "under-the-bonnet" rated LiFePO4 batteries for this purpose.

[@spassantechnik]

I like the idea but impossible in Germany. Such a tinkering job would fail the MOT 😅

[@CryptoShaped]

Great job, Headed your way now so you can replace all my batteries !!

[@user-ml3sz3mm5y]

That's cool, I'm thinking about getting a Chinese 16v100F assembly and sticking it in my car. But wouldn't it overheat in summer? These caps are usually rated up to 60 C, and their lifetime gets much lower as the temp rises. By orders of magnitude, in fact.

[@XeonProductions]

I have one of these ultracaps wired in parallel with 2 other batteries for my car stereo and mine sits in run mode all the time too, doesn't seem to affect anything. I'm using 2 AGM batteries and not lithium.

[@beasyphone]

These sell for 1000$ amazon- 499, any audio website 399.... cool video nonetheless, I run 2 ioxus +a red top optima 950 on my hotrod. I really like the results paired with my 330a/16v @3k rpm. No injection or spark issues.Cruising with the stereo-sits at 14.6 happy-batteries=600$ (ish) total. Zero battery issues for the price of a single blue top optima

[@Brandon_Neil]

5 months later you can get these under 150$ and even in 120$ in some cases. Looking a bit more interesting now huh?

[@arthur88888888888888]

In my car i was having issues with the lead acid battery dying after 1 year because the engine bay was too hot. Tired of that i moved the battery to the truck rear bay and it worked fine. Installed some maxwell capacitors and everything goes nice now. I just don't recommend installing the ultracaps in the engine bay because of the high temperatures.

[@seewaage]

Thanks for sharing this awesome project!

[@jamess1787]

Thanks for the update 😁. I need to do this for my cars... Eventually.

[@nirbhaokhalsa4636]

How are you addressing cold weather charging of the lifepo4 battery? Maybe, AGM would be better, at least in cold weather?

[@ajedgar8299]

I'm curious about the answer to this as well. I suspect since it never really discharges much the damage from cold weather charging is minimal. He has a similar setup in his car and one of his videos it is 8 deg F outside. :)

[@RedPandaMining]

Dude car batteries cost so much! Went to costco for 12 year old toyota and it cost me $300ish usd… Mad Electron change all my batteries plz

[@madelectronengineering]

I'll get right on that, lol

[@RedPandaMining]

thanks lol@@madelectronengineering

[@666Necropsy]

i had an AGM battery last me about 10 years. still had life in it when i traded it in. just got tired of servicing it.

[@retromodernart4426]

@@madelectronengineering Can this supercap type of setup be done on an E-Bike to extend the life of the E-bike battery? So that the supercaps are providing the power instead of the battery, resulting in less wear on the battery?

[@xTinBenderX]

@@retromodernart4426 yep look up electric bus Battery Supercapacitor

[@markmroz]

So I bought one of these UltraCaps to disassemble and use the caps for my own custom build. Well, I had to use a chisel and hammer to get the gray exterior casing off and found that the inside was completely injected with polypropylene; solid. I kept chiseling to try to get at the caps, but felt like I was nicking them too much, so I gave up. I guess I'll just have to use the UltraCap as is, or find a different method to disassemble.

[@haydenc2742]

The same one he bought? Dang..seems like they don't want people to get at the supercaps...fooey...but at least they work

[@markmroz]

@@haydenc2742 yes, the same one. It works absolutely amazing and the starter motor feels like it wants to spin the whole truck around. I installed it in my wife’s 2003 Land Rover Discovery. I ordered another one for my 2011 Land Rover LR4. I tried using a 0.1 ohm/100W resistor, but they kept burning up, so now I’m using a 55W halogen bulb as a current limiter and it works perfect.

[@RealPivotTV]

I have one that went bad that I was thinking about doing this to. glad I ran up on this comment...

[@markmroz]

​@@RealPivotTVThe one in my LR4 was causing it to throw codes like crazy, mostly related to transmission. I spoke with IOXUS and they told me that first gen of UltraCap had a boost/buck convertert that emitted high amounts of EMI. My guess is that this was interfering with the ECU, which is directly behind the battery. I purchased 6 bare IOXUS 3000F ultracaps ($30.53/ea) and bussed them in series and now everything works so good. Like Mad did with his previous build, I don't use any balancing, because the nominal voltage of the pack is 16.2V, and the charge curve is linear, so all the caps should stay safe. At some point I'd like to get at the capacitors inside the UltraCap module. I was thinking of trying to melt the plastic or use a wire brush wheel. I don't care about the electronics, just the capacitors themselves.

[@RealPivotTV]

@@markmroz yeah, I was wanting to direct it on my channel. Hey where did you get those caps for $30?

[@CAR-AUDIO-PRO]

Not sure if you tried to open up the Ioxus, but if you didn't and to anyone else thinking of doing it. Don't do it. You will never get to capacitors. Under the grey case the capacitors are encased in plastic. If you look at the bottom of the case, you will see the holes where the case was filled with the plastic. It is impossible to break the plastic around the Caps.

[@nirbhaokhalsa4636]

Thanks for the great info! Anyway these caps could be used to power an inverter for backup home power during a power blackout with or without a lifepo4 battery?

[@RaymondLohengrin]

I have been using super caps for years now. Super Caps have very little storage milli amp, a 120 milli Amps (not even an amp capacity) can however start your car, they just deliver a tremendous punch of power but you will need an actual battery to keep whatever you want running for a while unless you have numerous super caps in parallel to build up storage capacity. To power your inverter a bank of Lifep04 batteries will be best and no need for a super cap.

[@DMinerzChannel]

Great job can't wait for you to help with my car ..Over here!!!🤣🤩🤩

[@kennith.]

I did like the temp solution since it was smaller and more compact and all the original car wires reached. Why did you stopped using that, was it because the capacitors were smaller? Could you not have just added 2 more rows of caps to make it the same height as the Li battery?

[@bhartley1024]

I've been thinking of making a system like yours, but I'm worried about the alternator overcharging the LiFePO4 and the BMS disconnecting it from the system, allowing the alternator output to spike when the battery load is removed. I guess this wouldn't be an issue if the supercap is always in-circuit, but I can't be sure of that.

[@markmroz]

I would think that it should be okay as SLAs charge at a lower voltage then LiFePO4. You definitely need a resistor to limit the in/out current on the battery. I’m using a 60W halogen bulb as a current limiter because my resistors kept burning up.

[@SteveOfTheMountains]

Love this. Would love to know more about this unit. Any good for car audio? What about solar?

[@thirtythree160]

Have you ever heard of any device that will measure and record voltage and current for long periods of time? This device could watch for computers waking up or not sleeping.

[@Aridzonan13]

Good job. Not, thrilled you need an app to enable the run mode.

[@haydenc2742]

Yeah...if it becomes an issue...I'm sure he will gut the thing, and rework it to just use the supercaps and eliminate the bluetooth stuff

[@BillR-e2g]

This is the most amazing part. Can you believe how this would put an end to those KIA thefts? It probably better than a hidden kill switch.

[@RaymondLohengrin]

I wonder what was the total capacity or amps of the super Cap module or battery?

[@nirbhaokhalsa4636]

Thanks again. Where are the updates for this video? 👍

[@manuelstarr3602]

The little one you took out would have been fine, maybe slightly bigger caps.

[@RW1LD]

I would be cautious of that big orange resister on the left side... those things can get dang'd hot and melt stuff.

[@haydenc2742]

It's there to eliminate/reduce the current flow in and out of the Lithium iron phosphate battery...it's job is to allow at a MAX 20A flow either direction...discharge or recharge...it shouldn't ever have enough current flow for sustained amount of time to get too hot.

[@rhurtadorh32]

Wouldnt the heat hurt that capacitor?? All that engine heat🔥🔥🔥🔥

[@flexairz]

I am more worried about that tape...

[@arthur88888888888888]

Yeah. Capacitors like to work at low temperatures. The hood engine bay high temps wil make them last less.

[@user-yk2dm9hu5l]

This is what Im looking to do with my Etrike, except I want the LiFePO to charge the Supers and the Supers to provide the initial take off acceleration to ease the amp draw from the battery. If any one out there has real experience or knows where to send me, I would appreciate it.

[@SheikhN-bible-syndrome]

Great video yiu got a sub from me. Im picking one of these up tomorrow hopfully it helps my 3k amp

[@littlejln213]

How is this thing doing? I am thinking about replacing my red top optima with one of these. My optima will not hold a charge anymore. It sat for a month in the freezing cold and now will not take a charge.

[@paulshull9247]

Great video. Lots of good tips. Thank You n God Bless 👍

[@ceedubbz777]

Do you have any issues with cold temperatures and the LiFePO4 battery shutting off?

[@CaneBTC]

Interesting... my 2013 bmw eats batteries every 2 years as well. Not sure I could do this; there are computers involved requiring coding battery type and age as the charge varies as the battery ages.. or maybe it doesnt matter

[@ceedubbz777]

Do you know what the jump start option does on the app? I just got an Ultracap and it came with zero instructions.

[@patrickcallahan2210]

Still going strong?

[@Brandon_Neil]

Ready for an update

[@A2J_Tim]

im going to try one of these.

[@666Necropsy]

electrical tape long term is a bad idea. the glue and tape are going to make a mess once it degrades.

[@ivanjakanov]

i wonder if a thermal pad between the battery and cap bank would be adhesive enough to hold it, those things last longer than electrical tape, less vibrations than putting the battery directly on the capacitor bank. could still use some straps to make sure it doesn't move

[@markjonnet7885]

I was looking at the older Hybrid Supercapacitor you posted years ago, you used Amperics 3.0V, 600 f capacitors they don't seem to exist now. Can you recommend a quality super capactor? I purchased a 2.7V 500F1Set(6pcs) 2.7V 500F 35x60MM Farad Capacitor Super Capacitor with Protection Board1Set(6pcs) 2.7V 500F 35x60MM Farad Capacitor Super Capacitor with Protection Board that was junk. Any info would greatly be appreciated, thank you

[@GertvandenBerg]

I used Tecate group 3000F caps on my golf TDI

[@thirtythree160]

Do you have any idea why the car eats batteries every 2 years? Is it the quality of the battery or is the battery over used excessively somehow? Do water pumps or cooling fans run after the car is shut off causing excessive drains on the battery?

[@haydenc2742]

Lead acid batteries use lead paste in the plates in a grid...due to heat/vibration the batteries (ALL lead acid batteries) the plates will sufate and degrade and dissintegrate, the sludge falls to the bottom of the battery and ends up shorting out or loweing the CCA...this is why the much much higher dollar lead acid batteries use AGM (glass matting) to keep the substrate in the plates...but those too eventual sulfate up and wear out

[@arrich4605]

secured w/ the electrical tape isn't a good idea.

[@briantaylor6030]

Dealership opens the hood... WTF!!! 😮

[@ShafaqIftikhar-pw9ld]

First lol

[@dannyclark9820]

Having sold batteries for many years, they are only selling you the warranty almost all batteries of the same BCI have the same cranking amps if not more, they are selling a piece of mind and disguising it as a warranty

[@fiftysix.5.6]

🍜🍜🍜🍜🍜

[@Hertzsogood219]

No way I would put one of those in my car. The Ioxus super capacitor banks were recalled because of they were draining AGM batteries and catching fire. Why do you think they are going for only $129 b-stock.

[@alpaknan2189]

omg another linux user

[@benoittheminerandgamer]

Complètement stupide.. Tu achètes pour des milliers de $$$ en mining et tu veux meme pas acheter une bonne batterie a 300$ pour ton auto.

[@thirtythree160]

Do you have a pico scope that would measure the currents going in and out of the battery and the capacitor? Be interesting to see what kind of currents and created at start up.
