LAF- Lange Audio Fabrication makes acrylic cases for any size headway bank and they're nice

Yep what Bobby said! Check out LAF

What safety does acrylic provide? Lithium fire burn right thru that.

@@h8h81 just safety from preventing a pos to negative arc on the non main bus bars

64ah will fit nicely into those battery boxes from walmart

I totally agree! If you’ve got a serious system lithium is the way of the future

18k watts? So what would you suggest I do for my little 2k system? Lol as far as battery and alt upgrade

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.

How many cells?

How many times have you had to charge it ?!??

@@burr7367 since it's in a vehicle, it would be charging every time he starts his car, from the alternator.

lto is good if youre going higher voltage headways are where its at for stock imho

Thanks for watching

With a 16ah bank I’d say a couple of hours. If you built a bigger bank you’d be able to play longer

Tnx for the info

Nope not yet

What are you thinking of getting? Im debating whether to add another D3400 or an D4S LTO 6. Which would you choose?

@@hippo-potamus THE d4s lot for the size and compact wight

You can run these in line with AGM. You can use a isolator if you want, but it’s not absolutely required.

amzn.to/3NWFyxv

Project DB

I don’t know of anyone selling prebuilt headway banks, but surely they’re out there.

You’d get more performance out of the LTO 6 than the agm in a much smaller and lighter package

Maybe in the future

That’s a great way to extend the life of your batteries and almost no one does it

I wish I had some info for you on that, but unfortunately I don’t have any experience with any kind of smart charging systems.

@@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

kzfaq.info/get/bejne/rcyPp8ygmtLPaGQ.html

As he shows the headway rest a volt higher that's why you need an isolater I'll just take the AGM out altogether do a battery delete.

You just described the perfect set up imo

i use marine battery selectors and switch to front battery only when i park.

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.

This is a Schumacher can’t remember the model number, but I charge the lithium with a lil noco charger or my 100 amp power max usually

@@HifiVega I was curious about charging these headway cells with my Noco charger!

That’s a great idea man I def need to try that

With these cells yes, but it’s all about matching the charging voltages.

@@HifiVega sounds like I need to do some research 🤔

Thanks!

@@HifiVega ya buddy 🙂

If I buy one to use in my truck in the future probably, but I don’t wanna buy one just for the comparison video.

howd it go?

I'm already on my third alternator and have a stock 150 as well so curious how yours is doing?

You got the sickness lol

I have 2 90ah agm batteries what cells would I need to tie them together?

@@hausboxes You can tie as big of a pack of headways you will need to parallel the pack to your agms with a isolation relay

@@edud8452 so I should leave my 2nd agm in place and run an isolator between 8 cells in parallel off of my 2nd agm?

@@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.

Absolutely not. My 40ah headway wont even keep up with a smart5K

These aren’t great for under the hood and even if you had it installed inside the vehicle I believe I’d want a much bigger bank

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.

I meant to say that when the aircondioning is not running the vehicle's interior temp is well above outdoor temp.

I got a second battery too

The blue cells have a lower c rate (I can’t remember how much lower off the top of my head) the red headways are better for our application even with less AH

​@@HifiVegahe is talking about the sandwich or bread slice dimension cells the chinese knock off of the Toshiba cells they are much better 30c constant and 75c burst

​@@The505BassHeadget the 10ah scib lto cells big bro

You could add a active balancer or bms, but it’s not 100% required if you check individual cell voltages somewhat regularly

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.

@@HifiVega ok, but not "2 banks paralleled" but each cell has a parallel cell which is in series with the other parallel cells. Thanks for the video.

Yea 14.8 is the max charging voltage

If you’re using headway or something with similar charging range you don’t gain much by going agm outside of just pure ah if you’re going to be running the system for super long periods of time

@@HifiVega so no issue hooking up either to a stock charging system??

@@CrazyWillification headway yes LTO and most other lithium no

I assume that’s the same as a high rate flooded battery?

Sounds like snake oil 🐍 🛢

Battery hook up

Thanks. You can use a second agm, but I would stay away from capacitors unless they are 200 or more farad

Never meant it to be a fair comparison just a comparison folks are curious about

@@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

@@jamesvarner758 more lithium content to come way too much to cover in one video for sure

Yeah you could and adding another 16ah wouldn’t put a huge strain on the stock alt

@@HifiVega how big would the alternator have to be? Thanks for replying!

Hell yeah I did! #bassheadlife
