Lithium Batts and SUPER CAPS 

If you're boring someone that means they're not interested but for US Auto Audio Geeks we love what you're doing please keep at it you are doing an amazing job thank you for explaining to the public! Knowledge is power don't forget!

Dude, class is in session!!! I love this!!!! Thank you for taking the time to explain all this. It was VERY helpful.

please keep videos like this up. I have learned so much from you in my quest to master car audio.

I know this is an old video I'm sure you feel better but it's great you're doing this especially with Elysium talk videos you helped me out dramatically thank you

I'm so stoked! I have the sb630. Just bought 72 ah of headways they'll be on my table this week. Together, they're going to HOPEFULLY be fantastic!

I usually feel smarter after your videos, but I'm still feeling stupid. Time to rewatch.

Keep up the good work Edward! Love these informative videos.

Thank you for the extremely important information simplified.. Hats off to you for taking the time to share knowledge!!

Thanks Edward- watched a bunch of your videos, including this one twice so far. Would really like a basic diy charging and install video for super camps- seems like alot of the little guys (daily drivers, 1000,2000,3000 watt system guys), are looking to super caps tonadd to their stock electrical to sustain a basic, moderate system. Thinking about going this route myself, just still a bit wary of proper charging and wiring. Thanks again man!!

Thanks for this video. Thumbs up! Just want to say the actual difference between energy and power is time.

Thanks I been studying this stuff and have had the xs 500f and it amazed me. Took the place of a lot of heavy batteries. So I'm fixing to build this set up. Think it's gonna be great. New technology

@2:30 ESR is "Equivalent Series Resistance" not "Electrostatic Resistance"😁

This is so awesome, do you know how can this apply for camper vans and buses with solar on Lithium ion batteries?

What will you be doing for a balance board for the battery bank?

Great Video Edward, as Always !!!!!

Do you hook up the alternator to the super caps, then to the battery? Or battery to then the supercap?

35Ah size battery will deliver current 1A for 35hours at its given voltage. So 35Ah at 12V has different energy capacity than 35Ah at 2.7V. It is just a unit of measuring battery sizes. Great video!

Can I combine one bank of lithium and 2 banks of ultracaps in the trunk, with an yellow top battery under the hood ?? Oh and I have an isolator between the battery agm and the lithium bank

Still relevant and very informative. LTO batteries are the way to go vs Lead acid batteries. I'm replacing all my auto batteries as they die with them. Never have to buy another LA bat!

I love the informative videos.

Thanks for the video it's hard to find straight forward explanations. I can say as good of a job dumbing it down for the masses I was white knuckling a couple times trying to keep up and I'm pretty knowledgeable in sparks... Problem I'm having is trying to find out what the bare bones electrical system I need for my system. I will be upgrading over time as money comes in but I need enough to get my new amp functioning safely. My stock electrical 140A alt is running a AP apcle 1800.1 and a 1 50x4 A/B,, but I'm adding a 80x4 and replacing the 1800 with a CAB45 (5k at 1 ohm) when the finally ship in from the far I east. I found a good 275A (full amperage at 1200rpm) alt but what is the bare minimum battery setup just to get me up and running. XS says buy this huge agm or 2 of these smaller AGMs well I don't have $700+ at the moment... And have a regular flooded starter batt under the hood at moment which isn't compatible with much I've gathered. I also I will probably not be using the amp at full power at the moment my current 2 AB XR15 subs have a 1500wrms rating so a 5k amp prob be a bit much even with impedance rise. I just know I don't have enough self control to leave it on the shelf until I can afford to aquire all the optimal electrical component's I need what will get it up and running at a safe voltage until I pick away at more battery's ect. For a 2010 grand caravan Alt options are very limited 275A is biggest I've seen and no one offers a really big alternator or a bracket for double alternators It would have to be full custom install which I may do at some point I am a welder/fabricator by trade. Any input would be appreciated.

I’m going to get some xs power caps. Just not sure if the 2.7 or to get the 2.8

Your video was very informative, I've been on this path, but the farad to amp conversion confused me. If you have a chance I have a taramps smart bass 5k amp max draw is 475amps, I have 3 zoom 12v lifep04 100amp batteries, the bms on each battery is 100amp charge/discharge. So in experiencing clipping at higher levels, my alternator is a 270 amp. I'm thinking 1000farad super cap bank should keep me from clipping.. without the caps I can only deliver 300 amp from my batteries, but adding the caps should get let me deliver the 475amp to the amp when it wants it and should eliminate my clipping problem, right? By the way fit not into Scott the lifep04 batteries get are the zoom 100ah on Amazon, I was looking at the 200amp batteries, but they use the same bms so only 100ah discharge even with the bigger battery, each smaller battery they have has a matching bms. I tried the 50 ah version but that wouldn't start my truck the 100 does, the 300 no problem, I also had to get a voltage booster circuit as my Toyota only charges to 13.3 normally, with the voltage diode the truck charges to 14.3v but running the amp hard just below the capacity of the battery back (300) my voltage does slowy go down (270 amp alternator recharging 300 ah in batteries with over a 300 who draw 290 on the amp and the additionall amps pulled from Basic car function mean's I I'm pulling more power from batt than the charging system can recharge the batteries so I th How many caps will I need to to be able to supliment the 175 amps that the amp needs that my battery bank is short yes I could remove the lifep04 batteries and bms but then I don't have a charge control amto keep them from bushing info flame and keep them balances.. Will a 6000 farad capacitor bank keep

I'm running a SoundQubed S1-2250, how banks will I need?

so if i parallel a supercap with a deep cycle, does that up the output amp rating and would this allow the use of an inverter to not kill the deep cycle

Good job Ed

Good explanation.

how do I hook up the super cap banks to the battery? I am assuming it goes in between the amp and the battery? only the positive lead from the battery to the cap bank on to the amp? and the grounds only go to chasis? or does the cap bank ground need to go to the amp as well if both are ground to chasis they should'nt make a difference correct?

Hey man I was told by an xs dealer not to.use the sb5000 instead of the super caps... what are you're thoughts

To sum it up simple amount of supercaps need to buffer energy delivery while LTO storing reserved energy to feed the supercaps need more energy, add more LTO need more energy delivery, add more supercaps

I'm installing a capacitor bank in the trunk for my audio system. I already installed a cut off switch. Do I need any other fuses besides the one next to the battery?

you know what i would love to see? a build up video like stages in a video game. Ok hear me out on this. take a single 40ah bank and put said 20k amp on it. put a clamp maybe an smd amp meter at peak hold whatever and let us see how far you can get into the volume before saaaay 13v? as well as show us current pulled and how much wattage it put out. next add a single bank of caps and repeat. add a 2nd bank of caps so we can see the benefit and recharge speed change, repeat. then remove the caps but add another bank of yinlong so 80ah, repeat. next add a single bank of caps back, repeat. Yes im very much so aware that in a car an alt will be charging this but at the absolute very least it will give us a ball park to work with which is where a simple "results may very" comes in. edit: after watching the very end of the video i see we're on the same page lol, ive been itching to see a video like that granted i didnt think of doing single banks at a time for a modular configuration i was thinking more so of like a 10 bank bus bar and putting in a single bank in diagonally but still in the correct spots and then as i buy more sets of 6 i would adjust it to put the banks in say a V-ish shape? then 3rd bank ill change it so ive filled both ends and the middle then just fill it out from there.

I have around 100 ah of lifepo4 lithium (limitless) and a 370 amp alt. I have gotten 1 super cap bank so far, (getting more eventually) and my question is, is that 1 bank going to help me at all? I’m running 3-8k amplifiers, so I’m wanting to get- 3 banks of caps, but I’m curious if I run mine now, will it it bottleneck my amps when I’m trying to clamp over 20k? Like when the bass hits and the caps deplete completely will it essentially just act like wire and only charge at the rate my alt or lithium sends? Or will it negatively affect my output once they empty? I’m mostly just curious if I should not install them until I have enough banks? Thanks Ed!!

I purchased 6 LTO cells through your site and also caps from you as well. Only installed LTO so far and want to give my opinion. for all the guys talking agm, you can put 4 100a/h AGM truck batteries, big o' heavy bricks, together in parallel and won't come close to what 6 LTO cells can do. can provide the video of this very expiriment, although its in russian. The power LTO makes will blow you away. No agm, nothing under the hood, just those 6 cells in the trunk will run your car and run 3k watt system like you never though it could. now to the negative. it blew my trunk all out of wack, my $600 singer 350 amp alternator took a shit, my American Bass XFLs keep burning the coils and the orion XTR 2500d amp keeps on overheating. LTO will give you the power, the load, i promise you. can the rest of your system handle it? now the question to our fearless leader. would installing the caps in parallel with LTO smooth out the crazy power LTO demands and gives out. killing alternators and amps on the way? i assume answer is yes. please explain the wiring. from alternator "+" goes to LTO bank"+" then "+" on capsitors. The"-" grounds at LTO by going to the frame and then goes to "-" of caps. then amp + and - go to caps + and -, question: Do you need to ground the cap? The LTO is grounded mind you. next question" do the amps negative just go to capasitors negative or the frame? Guys get LTO, its the shit, real talk, but know it will be just a begining

Very good info, thank you ed

Good video bro!

Does it make a difference if you wire the amplifier (fused) to the supercapacitors (paralled) and then to a titan8 battery vs amp to the lto battery with the caps paralled to the battery?

im doing a supera plus and lipo4 bats solar system, not in car so this was informative TY

What supercapacitor would I run with 12.8 volt 750ah headway packs? Pulling around 3000 amps at full tilt spl set up. These are 3.2volt cells in series to 12.8v.

Hi I have a jump pack installed in a mechanic service truck for semi trucks using 4 rv’s batteries and I was wondering if I can add some super caps with my system to improve when jumping a truck. Please let me know if possible and how . Thanks my batteries provide about 3400 cc’s. Thanks . I also have 2 banks because I do 12 and 24 volts jumpstart

So let me ask this if you are gonna run both together how should they be In line with the stereo and wat I mean is wat should be under the hood wat should be closer to the amps so that they will work the best thanks..

So let me see if you think this is a good idea. I have a 2001 silverado with 3 batteries in it right now. 2 under the hood and a agm31 northstar under the truck. I want to add a limitless lithium where the agm31 is but I will put it in a sealed box to keep it from being cold or too hot. Then replace the batteries under my hood with the supercaps and I have a mechman elite 250a alt on there now. My amps are are 2 orion xtr 2500.1dz and an xtr 1000.4 for the highs, do you think that is a perfect combo for me?

Fantastic vid 🙂 I'm currently running a 320 amp alternator, and only one 80amp hour AGM for a 3300wt system. Works great except for speed of delivery.... Short duration voltage drops for kick drums and such. Getting ready to add 500 farads of super capacitors. I'm pretty sure it will be awesome. But thanks for this video, as it was a confidence booster for sure 🙂

If you were to wire a bank of super caps and a bank of lto cells how would you want to wire it from the alt? Caps then lto or vise versa and then where should you wire the amps off of the bank of caps or the lto or does it matter

im in the process of upgrading my bros system and was wondering if my electrical can keep a lithium happy. he has an avalon and we swapped his 80a alt to a 130a. we also did the big 3 with 0awg welding cable. i found relion lithium battery off craigs for $300 its a 12v 40ah. only info i found are charge voltage is 14.6 and float voltage is 13.8 its going to power up an orion xtr 2500.1dz to a sundown x12

4.5k system Xs sb500 34r One bank lithium 40ah Stock 130a alternator One run 1/0 Thoughts?

I have an XS- Lithium Titanite battery in stock location. What are my options for a cap with said battery ? Do I have to stay Lithium ? What are my best options ? Small amp and sub setup. 300 watts rms. Love your content, hope to view more... Thank you's

I have 2 banks of 6 Maxell Super caps (500F each bank) totaling 1000 Farads I see lots of arguing about balancing circuit boards.... the banks takes 16 volts but my car only charges up to 13.5 volts via the car regulating the alts output and I have tried different alts and that is where it sits. Do I even need the balancing circuit boards as the caps will never each there peak voltage and only be maintained at 13.5v

Can you run a SB bank n a lithium bank together?

If a use a LTO 6cell bank , on a car with 90A alternator at 13.5 V , i will harm the LTO ? I heard you need a 14.8V charge for a good protection for LTO , otherwise i will damage the LTO in short time. I don't know what to do , upgrade to LTO or to stay with the AGM . I'll be grateful if you give me an answer. Thank you

looking forward to this!

Harmon Kardon 4100msl bluetooth speaker goes into voltage protection mode when starting ATV. Battery voltage drops to 9.65V when cranking. ATV starts and runs great. What do you think I could use to keep the voltage up to the speaker while cranking the ATV? Thank you in advance.

Hay bud I enjoy the video , I have a little electrical education .I was wondering if you could do a video on those Toshiba ( scib) battery's? I'm interested in building my own battery. Thanks for posting

More on this topic PLEASE SIR

Ed, I have a 320a alternator and wanted to build a 320ah bank of 40aH LTO from XS, I have 36Cells right now and 1800amps of fusing for 2)8k's 2)600.2 1)500.4 1)400.4 all AAB series. So if I mixed Super Caps in what size caps and how many banks? And would I need a 2nd alt?

Can you make a system with a Tesla switch combineding LTO and supercaps

I have a 300ah yinglong bank with a 320amp alt. Charging 14.3. I guess I drawing about 2k amps for my salt amps on music. How would I determine how much power I can actually support¿ and for about how long¿ 🤔

I luv these videos

hello, can I use a normal BMS in a car audio aplication? someone told me that I cannot use a BMS because it cuts the current on the negative side, is that true?

Hey Ed great video. I've seen a lot of off-grade guys talking about the lishen 270 ah 3.2v lithium ion phosphate batteries. If I got four of them wired them in series that should give me a 12 volt power system would this be suitable for car audio? I haven't seen any of the car audio guys doing it but for a 270ah 12v end result the price send more than worth it?

Curious whats my best bet? I have 4500W Skar Skv2 ran to two 15” zvxV2s. Two runs positive, & ground 1/0, to amp front front…. Under hood ( might be done for) XS D3400 anyway, and in back 3 more to amp. & 240 amp X Brand alt. Im thinking lithium but these super cells seem more up my alley. Question, if i charge caps to 16v would i need more bs to hook up or being there agm its fine. Pretty much lith or spr cells? Thanks appreciate u.

If you put that 5000 watts in a 5000watt inverter .how long could you run a 1500watt heater ?

Hey Edward maybe you or someone here can help me I have a specific goal in my setup to not have any or very little voltage drop I’m at 900w rms in my setup a alpine pdx v9 I have a AGM 60ah battery under the hood and was thinking of a supercap by xs to help make sure that when I install my 250a H.O alt that my voltage never goes below 14v. So how do I achieve this ? Is a lithium battery the answer or a 75 farad super cap? So at full tilt I want to have and maintain 14v. I learned that voltage drop doesn’t just increase amperage drawn and amplifier output reduced but it also reduces the signal being amplified. So in order to retain the best audio quality I want to make my amp has all the power it needs and then some. I’m ok with overkill . It’s the motto in car audio So gents what’s more beneficial a super cap or lithium battery to achieve my goal??

More info like this please. I don’t pretend to know everything about everything and I don’t have the cash to pay for mistakes and I want a truly powerful system oh that’s sound good too. Bout to get a XSPOWER sb500 and upgrade to a 8k for my two 15’s

I am using 2 banks of lithium and 2 banks of super caps charging with a 370a alternator going to 2 MD8K'S on 4 15's. It idles at 14.7 and then 14.3 when I'm full tilt.

My alternator output @ 1800 rpm's is 408 amps. I will be running a limitless super capacitor bank under the hood. I will be running a 80Ah lithium battery in the trunk. System power rating will be 8k watts. So can you tell me how big of a super capacitor I can run in the trunk as well?

Can I run limitless Gorilla G10 and a 80ah bank of ying long together?

Im confused because I have an older 2 Farad precision power cap, and its bigger in size than the 3000F cap your holding..o.0 It said it was good for systems up to 2000w. Did technology change that much the past few years? Im looking into using some of the 4 diff old school car amps I have laying around, for home audio. What would you recommend to power about 2000w rms total? For my source I was going to use a blutooth/rca adaptor with my phone. I'm just not sure what best method is to power these amps for daily use. Ty for the very informative videos btw!

Does it matter when everything is in series where the point of connection is for amp as long as caps are connected in line somewhere?

Can one 500farad xs power ultra cap bank a 2 d3400 xs power batteries maintain 8000 watts

I have a question you may be able to answer. Can you connect a super capacitor bank with a lithium battery? I have a audio system that I'm putting together. Oh, and if so, do I connect the both paralled or series?

Awesome video man! Just ordered some 40ah xs yinlongs running 10k with a 400a alt ! See if this one bank of 40ah will do better than my 7 old agm batteries

can you run a lithium bank and capacitor bank in paralle?

"Welcome to showtime SPL, I love you" lol

Running a bank of 6 lto should I do 5 or 6 caps per bank? Charge around 14.5

It's time for an update video now that more products are available, as well as more information.

So question. I have a 2k rms sub and I want to use a sundown SALT3 amp. My car has a 150 amp alternator. How can I use batteries/caps to stay away from having to upgrade my alternator? How many amp hours do I need and what size cap?

I need some help. I'm running a Singer 320 alt with 3 Kinetik HC2400 batteries in the back with a Duracell Platinum AGM in the front. I'm having pretty badd voltage issues. I had the same system in my car (2 Fi Audio Q 18s on a Synergy Audio WFO 5.1D in a Scion FR-S) and I never had these issues, but once I put it all in my SUV, I now have voltage issues. The only thing that's different is the alternator is bigger (320 compared to the Singer 270 in my car). My question is: if I added a bank of super caps, would it be helpful?

The biggest advantage super/ultracapacitors have over lead or lithium (aside from cycle life) is the internal resistance at very low temperature. This means that the performance of these capacitors at -30C is almost as good as 20C. A lead or lithium battery at that low temperature is pretty much useless. Also keep in mind that the long term charge voltage of these capacitors needs to be lowered with temperature (typically 0.2V for every 10C over 20C. So a 2.7V capacitor should be charged to 2.5V at 30C, 2.3V at 40C…….etc

Thank you for the informative video. Can you perform a test on the charging of a 500 farad capacitor bank? Typically, the cap bank is connected in parallel with the battery, correct? So, let’s say that our alternator is charging at 14.3 volts while driving around listening to music on your way from work on a Friday. You arrive home, shut of the vehicle, and do not drive until Monday morning. Here is where the test comes to play, can you measure the voltage before you start the vehicle? It will probably drop to 12.3 volts. ( +/- a volt due to parasitic consumption/ battery resting/ stabilizing) for the next part of the test, can you measure the current draw of how much amperage it takes to charge the capacitor bank? Yes , I would like for you to put a high current amp meter on the cap bank while starting the vehicle. Let us ( the viewers) know what you get for a reading when you have the time.

My pcm regulator let's voltage drop to 12.5 is that ok on 12v lithium it recovers quickly

Can you recommend an LTO bank configuration and cells that will work best with my supercaps and my stock alternator my car is newer and therefore it would take serious customization to even make it work with the ECU controlled charging at 13.8 volts I have a 74AH lifepo4 battery lev60 cells from jag35 but everyone keeps telling me that lifepo4 has nowhere near the power of LTO is it ok to get something like a 40-45 AH LTO bank from xs power or something can I do that with my alternator people are telling me I can in a 5s configuration but how do I do that I'm really new to lithium and super cap I literally just bought both the one I have a month ago

Great video ED very informative

I have a small system, and have done all my math , big 3,ofc , upgraded alt , and have 2 agms, sub JP8 running slightly over 1100 watts around 13.8v at it's lowest, full tilt, can I just add 1 or 2 super caps??? 🤔 Or do I have to get all 6?? And would it help to keep me at 14.0v that's not far away.. please let me know your thoughts?? Thank you..

2.3 Lithium cell can be charged separately until?

Love these...I'm looking at the maxwell cap bank on Amazon for 270$ 16v 500 farad..to supplement the power....how good are they...xs power wants 440 for the same thing.

Oh mylanta, thank you thank you thank you! I've been wanting to know this exact info especially the AH ratings on lithium being so much lower and you sir have provided that knowledge. I've watched this video twice so far, now gonna watch a 3rd time for good measure. This video definitely earned my subscription. Again, thank you for such detailed info. Time to check out your other videos cuz you have a way of explaining things to where my caveman brain clmprehends.

You keep referencing alternators so I'm curious what size alternator you were talking about needing to run with a bank of lithium and a bank of caps to power 10000 watts

So I have a lithium bank now. I have a bank of super caps coming 500F what do I wire first after my front battery. Lithium than supercap than to amp or supercap,lithium than to amp??

thank you

Been along time since I have watched a Sparked Vid. I just got 2 D4S 6ah LTO banks and the cap bank. I tried to DIY however I got immediately discouraged when I bought a Mouser Electronics capacitor integration kit. I thought that the caps came with it. The kit looks like an BMS built into the buss bars. I contacted loxus and was directed to caps. The cheapest was the D4S 500 Farad bank for 300$ and change. I bought it however it's all bussed together. Is there any additional advantage to having balanced capacitor cells? Or is it necessary? Why would loxus sell integration kits however send the same customers to an XS power dealer for the cells. I have a 250amp JS alternator big 3 to an Deka Intimidator group 34AGM and then the 2 6ah LTO banks bussed. Do I need to worry about balanced caps?

I can't find that XS YinLong LTO on the XS website.

My man I learned a lot from this video very helpful I would give u double likes if I could

I have a question? If I buy a 100ah agm or 100ah lithium is that not the same

I am so late . But awesome awesome. Just gotta watch and listen. You cover it. I'm just saying. Thanks you did great

The real reason why the manufacturer is Yinlong is that Yinlong produced a lot in few years ago but couldn't sell them and disassembled from their unsold E-bus a lot, so they had a lot of LTO cells in stock, so they sold to dealers and came to an agreement to say they were partners.

Can porous carbon create more high power density. I always had that question???

I have a 2017 Silverado 1500 LTZ factory electrical system. I think the alt is 150A but has the stupid system that only runs the Alt when voltage drops to low level or load rquirement is increased. I have a 3kwrms amp and it keeps hitting protect mode. I know i need to upgrade my battery and alt but I am trying to find the cheapest most efficient resolution to keep me bumpin until I can afford all the upgrades i need to be done. If anyone can help with this I would greatly appreciate it. I was thinking of trying to use either a PowerMax 100ah or Taramps pro charger/power supply 120A ac to dc power supply just for the Amp because I have an AC outlet available in my truck. I am feeling overwhelmed with all the different batteries, caps, power supplies, etc. Please help! Sorry for the long post!

I am looking for something for solar that can maximize solar wind and mechanical for 220v water pumps and such

Hi, I have 42 cells 3.2v 40ah, so I would to know a configuration to build a 48v bank, can you help me?
