This is an awesome comparo! Somebody needs to make a small case for those Headways so you can safely mount them in a trunk. I know Parker uses empty battery cases for his, but he's using more cells too.
Any position isn’t true.. most agm tell you not to invert them.. also where discharge rate really comes to play is lower notes.. this isn’t a typical 40hrz type test.. you should run more like a 30.. Even if for comparison this was apples to apples where the headway will really shine is extension of deeper notes.. the lower the nite the harder it will draw and faster it needs the power source to respond.. it makes a huge difference on how low something does or doesn’t get
I run 64 amp hours of Headway cells assembled in a empty battery case powering a Taramps Smart 5k and a Kicker ZX550.2 . Voltage never drops below 13.4 and keep in mind this is my main an only battery for starting and powering my audio equipment. I keep it in the trunk area. Running for 2 years strong an never looked back
mustang6035 did you assemble yours or purchase it ready to go & install? Asking because I'm wanting to switch from agm to lithium but do not know that much about it. I do not want to do anything wrong. When I first get my lithium I'll probably be running something slightly similar to you, a smart5 and a couple 110.4 channel amps. Then down the road I will more than likely switch out the Smart5 for either the 8k amp I have or purchase a 12k. Assuming I should probably give myself some headroom for later & just go with more ah than needed when I first get my lithium.
@@itdoesntmatterwhatyourname6128 The lithium chemistry you choose depends on where you live and the minimum temperatures in your area. If you live in a warm climate near the equator where it never gets to 0°C or 32°F, Lifepo4 (Lithium Iron Phosphate) cells, like Headway or other types of Lifepo4 cells are perfectly fine. If you live somewhere that gets cold in winter, then you should use Lithium Titanate cells. Yinlong 40Ah cells from China are probably your best choice for building a Lithium Titanate battery. You can use and charge Lifepo4 batteries from 1°C or 34°F up to something like 160°F or so. Every battery has a spec sheet that will tell you the operating range for temperature. The point of this is to say that you can't use or charge a Lifepo4 battery below freezing. You would have to set up a heating curcuit to keep the Lifepo4 cells over 32°F or 0°C. Some might be able to be used to -10°C or 25°F but you really shouldn't use or charge Lifepo4 cells below freezing. If you live in a place where the temperature goes down below freezing at night and during the winter, you are going to want to use Lithium Titanate Cells, like the 40ah Yinlong cells you can get from BatteryHookUp.com for $199 for a fully built and ready to use 12v replacement battery. Its only 6Ah for $199 though. It is however pre assembled with welded with thick aluminum bus bars. I believe XS Power also has rebranded 40Ah Yinlong cells. They are 2.3v each, so it takes 6 cells in series to make a 12v replacement battery vs the 4 cells in series you need with Lifepo4 cells. Building a Lithium Titanate battery for car audio is definitely going to be more expensive than building a Headway Lifepo4 battery. They can both do a great job keeping your voltage up higher, and they usually weigh about 70% less than lead acid batteries while being much more energy dense, and faster charging and discharging.
As many people know, I ran 8 of the Duralast Platinum H8 (same battery in this video different label.) in The Audiopipe Blazer for a few years coupled with a group 34 AGM under hood. I never had any issues so to say with the batteries themselves, however even with dual 320 alternators I would see voltage drop into the low elevens at times. Adding a 3rd alternator did help with voltage, but still dropped into the mid to low 12's. this was on 18k watts by the way. Never had any issues, and the batteries recovered quickly for what they were, but you could notice a difference after a day of demoing at a show (would see a resting rate in the 11's alot). Only other con I can say for them is the weight and size, they are big heavy bastards especially running multiples. 1 more con I would say is hooking several of them up at a time kinda limits you on configurations. Over all though I can not complain, they did there job for what they are. However switching to 2 Cyber 12k's which is Lipo4 cells with a cap bank is complete night and day difference! Voltage has never been lower than 13.4 when demoing! They recover almost instantaneously, equipment runs much cooler, and all 3 alternators don't have to work nearly as hard! Also saves me about 600lbs of weight and gives me much more room! If your on a budget, I'd recommend the AGM all day long, for the price, warranty, and free replacement you can not go wrong! When you have the opportunity to make the switch though, I'd highly recommend it! Your equipment and charging system will thank you later! Great video! 10+ stars!!
@@nicolumens3311320 alternater 3 agm one under the hood and 2 in back you Gucci more the enough power for a 5k just incase you decide that’s if you’re just a basic street beater but if you serious lithium!
ive ran headways since 2017 or 2018. they work great finally had a cell fail out of the first bank i built all the rest seem fine but ive decided to totally rebuild that bank and use the old cells for a portable camping pack. other than that one cell ever pack ive made is still working
Each headway cell is 8ah, but when you series them you get more voltage not ah. With that being said I have a 4s2p configuration meaning I have 4 in series to achieve a nominal voltage of 12.8 and 2 banks paralleled giving me the 16ah battery.
the lithium is just so much more efficient with the current and isn't as stingy with it as the AGM. when done right/safe, there's no way you can overlook lithium.
is like to see the draw of the amp and see how fast power is returned to system in a running car with only the swap of the one battery . then after that test do a big 3 .
I'm running a couple hundred ah at this point. I REALLY wish I'd have sucked it up and got LTO cells. That being said even with a high end agm, the headway cells charge and discharge SO much faster. Great video thanks for sharing. I'm down with battery testing let's see it!
I have the same h8 agm with a agm group 65 under the hood. I’m thinking of adding another. Would I be better off adding this lithium to the existing set up? How many watts can the 16ah lithium support? Thanks for the info
2 banks of Each bank with 40 cells and a set of ultra caps. feeds a sfb-8000.1D feeds 2 avatar stu 15". Was doing a normal compact c-piller wall but changed up for a bandpass with a 30-80hz range shifted some seat brackets around to gain apx 5 more inches of rear space (need to keep rear seats got kids)
I got a 64ah headway bank I made. Its just like 4× that size in a 4s configuration. It'll run my whole 5k rms system and my Mercedes. I just worry about cells failing, but you can get a nice bms to monitor all this. This is a great example comparison tho!
Well because you using lead acid battery charger the estimation of that device for lithium's state of charge is way way wrong simply because lithium's battery voltage is always 0.8v higher than that of AGM battery 🤗 so a dead lithium at 12.8v is same voltage as full AGM at 12.8v the only difference at that voltage is that one is dead and other one 100% full 🤗
Is lithium ok on a "smart charging" system? I have been warned not to do a big 3 on my GMC Canyon because of the smart alternator. The lowered resistance has been known to cause some issues with batteries overcharging and random electrical glitches/issues in the system. I am only running a JP8 @1ohm right now but am wanting a moderate 4 channel for up front and maybe a 5k-8k for the subs at some point but not sure if it is doable without a lot of headaches on this vehicle.
@@HifiVega Yeah, it surprised me when I started reading warnings not to do the big 3 on it. I have an old 94 Ford Ranger that needs some minor mechanical work that I want to try my hand at a blowthrough with. I may have to stick to my JP8 in the Canyon and save the big system for the Ranger, Anyway, love the channel and thanks for the reply.
My 2015 mustang has a smart system and has never had a prob running multiple agms. stock alt was 175 and simply adding a 4 gauge power wire to stock electrical resulted in noticeably better voltage and increased output from my amp/ subs to the point that even my girlfriend noticed a big difference. running mechman 240 alt now. i didnt run my additional charging wire through the "clamp" sensor that the factory power wire has around it. i believe that clamp sensor is how the vehicle's "smart" alternator charging works and may have something to do with me not having issues.perhaps you could research that
Us agm folks need to get over the initial sticker shock of lithium I was sold on the fact that lithium out performs agm by every measure but for some reason it took a lot for me to get through my thick skull that lithium is actually cheaper all things considered that's because you need much less ah of lithium as u do agm and this vid proves it. 30ah of headway will put my 300+ah of agm to shame whilst taking up half the space and a quarter of the weight.
Just an fyi you don't have to use automotive style agm batteries. You can use sla agm batteries like what you find in wheel chairs and mobility scooters. They are way cheaper and they come in deep cycle agm gel too.
I built myself a 32amp hour lithium headway battery to run my cab 22 with an audison apf8.9 bit for mids and highs. I'm hoping with my stock 150amp alt it will hold good voltage. 😂
Vega thanks for the video, it helped me a lil bit. I'll take every bit of info I can & appreciate the help from your vids! I've been wanting to make the switch from my Northstar AGM to Lithium I've just had so many questions & still feel like I know very little about Lithium. Hoping to feel comfortable enough about my knowledge of Lithium within the next couple months so I can pull the trigger and buy my first Lithium setup.
Great video can I use that lithium battery in my room? I have a audio system installed in my room. And should I use a specific charger? And also can I used it in float mode while listening music? Thanks a lot .
Can I replace my regular car battery with a 16ah lithium bank as long as I relocate it to the trunk? I currently have a 64ah on my system and wouldn't mind having another lithium for the car to match it
Question that i would prefer answered by you HiFi Vega, or an equally experienced car audio enthusiasts. I'm running a stock 103 amp alternator. This alternator is powering a stetsom ex3000 black edition 1 ohm amplifier, pushing a Avatar SVL 1547D2 wired to 1 ohm. I have the ioxus 12v 375 Farad ultra capacitor wired in parallel to an xs power d3400 under the hood. Wiring has been upgraded. Big 4 under the hood done with quality 1/0 ofc and a 4/0 high quality pure copper welding cable ran from front battery to ioxus ultra capacitor. I had to explain all of this to get a correct answer. My question is will a lithium bank such as this or another quality lithium bank make it possible to run my system without upgrading my alternator? I'm at the point now that i need to find a way to increase power. Thanks man
Yes and No. first you would want a bigger bank than this. I’d say at minimum a 64ah headway bank. That would let you cheat the system a little bit depending on how much power you’d like to run. That being said at a certain amperage draw point you’d need to upgrade your alternator to keep up. So the answer boils down to how much power you want to run. 5k is attainable and reasonable with the upgrades you have already and a lithium bank, but when you start getting into the 8k territory I’d probably suggest a alt upgrade
@HifiVega THANK YOU!!! I really, really appreciate your response my friend. I think my car answered my question for me lol. I want to the store shortly after asking this question and my alternator is crapping out. So. High output it is. I am leaning towards 320amp. I do not plan on going much, if any, bigger than I have now. Maybe another svl-1547 down the road, but just the one does pretty good. I appreciate you my friend. Thank you.
Can spmeone comment on the AH part of comparing AGM to Headway cells ?? I want to run three 96ah headway banks in a large boat build. We domt sit with the engine running so a large bank is needed. I will be approx 10k rms. I added a 270 amp alternator to charge back up in between party cove visits thru the day. Still trying to figure out if 300 ah of headway diy, is better then say 500 ah of agm..
My Headways are set up in a 4s6p 48AH config they tie into both my 52ah agms when the system is on. I figure im pulling around over 3000 watts or more when full tilt even with the priuses 100 amp charging sys my voltage just doesnt drop. I even have a 4 cell pack to start my waverunner🤣👍
@@hausboxes you can do that. Ive got my 2 agms tied together and isolator between them and the headways my isolator is tied into the amp turn on wire so my headways aren't tied in unless the radio is on.
Can you use these Lifepo4 batteries that are selling all over the internet as a power bank for a large 10k watt boat audio system ? Interested in non engine running party cove setting. How do the lifepo4 batteries work vs these ? Also, some of the lifepo4 batteries have built in battery management, is this good for or not for this use ?
You can't necessarily just plug a lifepo4 battery into a charger and take a capacity reading. The discharge curve is extremely flat and requires tracking of watt hours in and out to know what the capacity is at any given time.
Great stuff! Very interesting comparison indeed. I’d never really considered the headway bank, until now..i thought the headway bank would be cost prohibitive. Thank you sir. SUB’d peace out..:) Oh, please do run the AGM vs The flooded lead acid battery comparison
I made a 2p4s headway pack for my side by side. I 3d printed cwll spacers and a case out of flexible tpu. Provides plenty of starts and less voltage drop when using the winch.
As always thank you for the videos, audio, tutorial, demo, comparison great information & content. Remember BASS in ya FACE HiFi Vega 🚙📻🔈🔉🔊🔊🔊💨💨💨💨💨🎼🎵🎶🎵🎼🎶😁
Deep cycle AGM batteries on hybrid cars, to drive ECM and cars, with alarm, and electronic key entry and startup fail with low milage . These Aux batteries are common on total electric vehicles also and are not part of off road charging cycle. I keep mine charged up each week, especially in the Winter. I added a charging connection to my Hybrid Lexus to AGM battery in the boot. Even Teslas fail due to this issue. I keep a Hilti portable charge pack in the car also, very compact, just in case. I broke down once due to aux battery failure in the past, never again.
Does a person make the headway bank or can you buy it assembled and for how much?? Good video. You know maybe a good video would be comparing different lithium batteries and current price. 🤛🥋🤛
I really do not understand about how lithium battery banks cannot be placed inside the engine compartment when the average temperature in the summer in Arizona is around 105 degrees. And when in the vehicle with the Aircondioning going it's well above that,so the location of the battery shouldn't matter in an environment like Texas, Arizona and Southern California.
What is the Make/Model of that charger? I bought a variable output DC power supply to charge mine. I can charge them individually @ 3.2v or assembled @ 12.8
Thanks for the awesome comparison. Im not an SPL kind of listener. Im more of a SQ music in a moderate level of sound. Question, how long do you think that size of a lithium will last in minutes before it shuts of. +/-500w system in moderate volume level. I just wanna have an idea of how long can I play my music while Im in the car. Thanks.
yea i have the xs power d3400 under my hood and 2 xp3000 in the cab of my yukon but im gona be swiching to lithium when the life cycle of the batts are up good vidoe
@@HifiVega fair, but as a guy that has felt the raw power from lithium ion battery bank vs from my alternator, the difference is wow. However the price difference can vary, and how to truly maintain lithium is much more complicated. I don't have the face for youtube, but hope in a later video you can get a better run down of switching to lithium ion or lithium iron phosphate
