DIY Lithium! 64AH for Under $400!! Car Audio Battery

[@kswis]

This is the first time I've had the 72 ah of headways in my whip for more than a 10 min torture test. Dude, Parker get some ultracaps to go between your amps and headways... brah I've been doing this a min n I'm telling you, ultracaps AND lithium is whas up man... research it if you want but an xs power SB 630 farad in my little 7-9k system has my voltage more rock solid than I thought poss! for approx $800 for lithium and ultrcap... im surging almost 800 amps and steady 13.8-14.3 the ENTIRE time... Level up brotha! Thanks for turning me onto the headways! So glad I took the plunge!

[@davidoutler2854]

I have been following your videos for a few months now, I’ve started putting together a setup of my own. I just have to say I appreciate you putting in the time and sharing what you’ve done it’s been so much help.

I have a high amp alt with big deep cycle for 2nd battery. Running skar 4500.1. My deep cycle does pretty good but lithium would take me to next level..

[@rustywrench500]

@@lesteranderson3350 have you looked into yin long? They make amazing lithium batteries, I would say that the option in the video is a really good one but if you're not familiar with batteries on an advanced level then there are some major risk factors, but if you know what you're doing then this is a very good solution and very cost effective as well.

[@catch22frubert]

This was an awesome surprise! Great to see you tackle a DIY lithium battery. I have been wanting to do a lithium battery myself for a couple of years now, and i've done tons and tons of research. The absolute best cells to use are A123 Systems 26650 cells. They are little 2.5 ah cells, but you can get a box of 100 cells for about $500 if you are lucky. These cells are capable of 50 amps continuous discharge each! to put it simply, 100 cells make a 62.5 ah battery that is capable of 1250 amps continuous discharge @ 12+ volts. It would support 15,000 watts continuous easily and 36,000 watts burst for 30 seconds.

[@ParkerTheBasshead]

That’s awesome man!

[@catch22frubert]

@@ParkerTheBasshead If I'm lucky enough to get my hands on a full box of the A123 systems batteries while NY is on lockdown, I will be sure to post a video of it running my Orion XTR-2500.1dz so you can see how well it hold voltage. To be honest, I have the knowledge, and the free time these days. I'd love to start a lithium battery company. I would have to call it "Electron Bomb"!

[@jkbrows1095]

@catch22frubert 50 amps from a 2.5ah cell is 20c but the headway’s are actually capable of 25c so his 64ah bank could discharge 1620 amps with large enough busbars and equipment to handle it. There are multiple brands of LTO cells and LiFePo4 that can discharge 50c to 100c as well. If you are mainly looking for a lithium cell with a high C rate there are a few better options out there, and I realize I’m 10 months behind, so you might have already learned this on your own. I was just trying to help out cause I spent a bit of money buying the same exact cells then started finding so many cells with higher output and I was pretty upset.

Great video! Just one recommendation get an HA02 balancer they're more expensive but it will work better and last easy longer than that $10 one you have.

[@catch22frubert]

Absolutely 👍, look into some higher quality BMS options, and maybe a lithium battery charger to hook them up for a proper balanced charge once or twice a week.

[@mazda2284]

i disagree , that balancer way more expensive and way overkill being that it will do 1000ah no problem , another factor is balance rate the HA02 only does 2mA balance current in our application , this balancer does 1.2A current for balance !!! so its way faster. @catch22frubert a full blown BMS for our use would cost 5 times what this bank cost IF you can even find one ... typically a bms for something like this would have to be custom made and most likely be from a china company .

[@mazda2284]

@@catch22frubert also NO !!!! DO NOT put these on a charger once or twice a week , you will ruin them ! these are not AGM ! its 100% pointless to charge these unless they are low like below 11v , and in that case id use a variable bench power supply not a charger designed for something specific . the bench power supply can be used for anything 0-30v

[@Up2Trbl]

I've been doing a LOT of research on these headway banks, and I'd really like to build one for my system. But my alternator charges at 14.9v, and I can't find a solid answer on whether or not that would be safe with headway cells. Don't want to start a lithium fire in my truck 😂.

[@jeffsenecal4168]

Hey Parker love the Vidoes, how do you regulate the flow from the car alternator to the bank? I know u have balancer, but that's not a amperage regulator, and there doesn't seem to be a BMS with a high temp low temp, hi voltage charge cut off, or any kind of high amp cut off protection, and no bluetooth to watch the bank. I'm glad u put itbin the battery box though. Just wondering, thanks!

[@mikehoncho5360]

Me too

[@babyTOY-YODA777]

Good point. The alternator will regulate voltage and current on its own, based on the voltage provided fielding it, as well as the control input from the PCM. However, lithium does not charge the same as lead acid. 99% of vehicles from 90s to 2010s will only allow the alternator to charge around 2 to 4 amps unless the load is particularly high for some reason, like fans and lights are on. So there is regulation, it's called a voltage regulator and rectifier bridge. In a real serious setup I would use or make my own separate regulation control.

Headway has 3.2 v 8ah lifepo4 cells , how many of those to build a 64ah battery pack?? If on each individual cell it says 3.2 v 8ah , why do you need 4 to make 8ah ??

[@ParkerTheBasshead]

Because you have to run 4 in serious to get 12v. 1 cells get 8ah at 3.2v, 4 cells gets 8ah at 12v. So you need 32 cells to far 64ah

The balancers restrict the amp draw. Basically like putting a fuse on the battery. If u get a 100 amp bms and your system draws 150 amps then the bms limits the draw to 100amp. U don't NEED a bms they usually cause more harm then good

I heard that you can’t run a lithium second battery if you have a stock acid battery is that correct? If you go lithium than even the battery under the hood has to be lithium unless I have heard wrong.

[@ParkerTheBasshead]

I would run lithium with a regular battery but you can run some lithium with AGMs

[@SpudicusMaximus]

The issue is resting voltage. Lead acid/agm rest lower than Lithium. What this does is cause the lead acid to suck power from the lithium while your car is off. So If you drive it daily, it's not that big of a deal, as the alternator will keep them goth charged up. If you are really worried about it, you can separate the lithium from the lead acid using a relay.

[@ParkerTheBasshead]

Yeah man will once I get back to my computer

Jehugarcia has a video on how to make this battery with all the parts in the description

[@connorwhitaker610]

You can get the superbeast which is 96ah of headway for $250

[@teamhud]

after seeing this two years later I decided to build a 96ah bank for my system. Hoping to stay above 13 for a full demo song. With the old battery I had in my car Id drop below 10v and my voltage protection system would cut on.

[@ParkerTheBasshead]

Yeah man they are re going two years strong!! You should stay in the 13s no problem

[@stanmondzelewski9253]

How would you hook this up to charge with your underhood lead acid battery and alternator?

[@BillyRay501]

Did u balance them out before setting it up
