HOW TO BUILD A 64AH 12v LITHIUM BATTERY FOR UNDER $300 (Full Process From Start to Finish) 

Thanks for keeping this straightforward! The top balancing was the most simple and easy example i've seen.

Awesome vid man, great info, the best one I've seen on this so far. Very easy to understand and accomplish. Two thumbs up. 😎👍👍

Great build breakdown seems so natural for anyone who are mechanically inclined thanks.

I have watched a lot of these headway videos in the last week because I am building one on my channel. Robert this is the best out of all of them. Good work bro!

Great video just started learning how to build these banks

Great build breakdown! Thanks for sharing.

Thanks for sharing a possible cheaper option. No stranger to hooking up and running stereo Amps and electronics having stacks of all sorts. Was surprised this Xmas with an Orion XTR 750.4 amp to run my 1in Dome tweeters, 6.5in mid range speakers, with a resister box's in all four doors in my VW Sleeper Wagon. Tested the Amp last night. Sounded fantastic. Being that I plan on picking up a 1ohm stable monoblock to run a custom boxed 10in subwoofer so this kind of power should definitely assist in that. If my transaction with them goes well I may order more as I have a 1200watt power inverter capable of being ran with a solar panel setup so a storage setup will be needed for emergencies. Thanks.

Prices have increased over the past few months. In January, I built a 300 amp/hr battery bank with 3 separate dedicated 100 amp BMS modules for about $900 from battery hook up. Deals are out there to be had, IF you are willing to do some assembly yourself. I put my lithium battery in my RV. Lithium batteries are awesome!!! Love your videos!!

Love your videos. Your video about the 18-hour bank gave me the encouragement to build my own and I'm so glad I did I have had mine for a little over a year now on my single zvx 12 and what a game changer. Thanks for all your help🏆🔊🌪🌪🌪

As the owner of ITTY-BITTY-BOOM Lithium I build about 500 hundred Headway banks this year.... I highly recommend for a super budget friendly bus bars, Jim's ECO Headway bus bars... I personally tested that PCB board and it got really really hot

Great stuff!

I got a 64ah headway bank in my car. But I've got custom $180 buss bars. And a $60 battery box from ali express. And heltec balancer. Keeps my 5k rms system running top notch! I've got a 300a alt too.

Hey hifi..I wanna run my 48ah lifpo4 in my audio system but not sure if I can run it with my AcDelco sealed maintenance free(smf) starting battery.. How could I get it installed without worry?

Where did you get the 2 gauge bare wire terminals link plz having a hard time finding them

Man, this makes things so much easier.

Pretty awesome.

Sup HifiVega, PCB Busbar 29$ comes with pair already?

noob here i have the exact set up and same wires in the same spot but when I plug the balancer in it starts to smoke voltage is 12.75 what is cause it to smoke

How many watts can a 64ah take?

FYI it's not off balanced unless it's charged that's how you top balance it's you can balance without it being charged but the term top balanced means that you charged it to the top and it's balanced there

Is there any space between the cells so I can put cardboard or if I decide to vinyl wrap each cell they will still screw on.

How’s your battery working? 2 1/0 copper lugs has more copper than that whole green pcb. Its basically copper clad, or copper foil. I double the 500a pcb boards on mine, works great! but now jag35 has 1000A pcb boards for $75 shipped. Next time I will drill out two 6”x12” .125”copper plates cost is about $120 but worth it. I’ve done it with 1/8” aluminum plates. Basically use the pcb as a template.

Do the screws come with the cells or busbar? All I need to buy is foam and speaker wire correct?

You can get 96ah for $250 by buying the super beast and changing it from 24v to 12v

I’m wondering if I were to build this, should I buy say like 35-36 cells and throw out the worst cells? Or would I even be able to tell if they are bad cells with using a multimeter?

Say Vega, where did you get that box of headway cells and for how much?

Hello, which would be the best BMS for an array of 8 batteries? I mean 12v 16amp. Thanks in advance

I got 2 of the new alpine type s 12s, with about .9 cu ft each, sealed, in an under seat enclosure. I'm powering them with an audiopipe 1500.1 rn and it's kinda really lacking. My electrical is capable of 3k watts so what Amp would you recommend to get the most out of these subs, with more sq, but also not being insanely expensive

Safe? Are these prone to fire?

If I build another one can I run them in parallel ? Only wondering cause it would be two different battery balancers .. thanks :))

Hi Man.are this used headway cells are reliable from seller you have provided in comments.

It isn't ideal using the selected active balancer on lifep4 batteries. lifep4 have a very flat voltage curve while charging and discharging, this means that the output voltage during most of the time the cells are in use will almost not change. This means that you only want to balance lifep4 battery towards the top of its charge when the voltage difference is more significant so above about 3.3v irr. The selected active balancer will try and balance the cells all through the charge cycle of the batteries, and unfortunatly has the oposite of the intended effect and causes them to become more out of balance because it can't see a real difference in voltage. This causes a very serious problem when you come to fully charge it because you have chose a balancer rather than a BMS (battery management system) that it will not stop charge when one cell goes over it's maximum voltage which will significantly reduce the expected life of the cells. Unless you are charging the cells at less than the 5 amps the balancer claims it can handle (which is usually not the case). At 5 amps it would take about 3 days to fully charge your battery which I think you would prefer not to do.

Did you have to solder the positive and negative posts that come with the kit or do they come attached to the pcb board or do you put them into holes and solder them. On the board it looks like the 2 positing and 2 negative post to add lugs too. Those come attached

👍

So what’s the condition of the headway cells in comparison to new headway cells?

Other than the 500amp bms any reason to build these when Amazon has 100ah batteries for less than $300??

is that bus bar suitable for a 6000 watt car audio system?

Hey HifiVega, let me ask you something and see what you think. If someone was to run headway cells in a vehicle with an AGM under the hood, the cells wire into series with no isolator. Seen someone do this, and how well would that work? Anything helps, still new to lithium.

Hey HifiVega like your videos I have a question how many cell I need to make 96 to 100ah

Hi, what applications can that be used? Does it works for car audio?

not interested in building batteries personally but still a good video.

I have an xspower 127Ah agm. How would these cells compare to it? Would there be any gain?

this is a 12.8 volt battery pack but most car audio alternators 270,320,370 amps charge at 14.9, can this lithium pack br charged that high?

Excluding large current, you could buy a 12v 100ah Redodo battery for this price

How do you (safely) use a battery like this without a BMS? These cells are known for being able to put out a lot of amps in a hurry, and for taking a lot of amps when charging, so how do you regulate that input and output if you're not using a BMS? Balancing cells is great, but a balancer is most certainly not a BMS.

Did you make it to Iasca finals this weekend?

How's it holding up?

How many watts is this rated for

how do i charge it?

👀

Will two of these hold a crossfire 16k

Is this safe for a knoob?

You forgot the 180a solder terminals that are packs of 10 on AliExpress for $28 🙄 shit annoying AF. I bought 1000a busbar for $75 only to realize it missing the terminals post 🤷

Can you build one n just sell it to me? Lol thought I'd ask..

please tell me you are NOT recommending this pcb crap for bussing ... there are so major major problems with using that . heat especially!!! project db discount code audio has properly made bars for car audio . do not skimp on the bars !!! they are very important
