Building the BEST BUDGET DIY LITHIUM BATTERY for Car Audio  

I love battery builds.

Looks good and deal for sure. Can't wait to see how they perform!

I tried using one of those little amazon balancers. They're garbage. Smoked mine upon hooking up and it was all correct. Used the LIFEPO4 red Headways (4s4p). Top balanced for a day and they have been installed for a few years now and the sets of 4p still have the exact same voltage, so I've just been running without a balancer. Only have 2.5k total and never run at max volume, so it's never under any stress. My issue with the LI-Ion (aside from being less stable tech than LIFEPO4) is the voltage. You'd need to charge at 16.x and can't mix with LA/AGM, where as the LIFEPO4s are within .2, so no electrical changes needed, just add and go. For a test bench though it would be fine.

I love this subject and it looks like you hit gold with the price point. Thx Rob!

Yes definitely more of these as you can

Sweet video! Can't wait to see the test video.

How are you doing Mr Vega please don't ever change your awesome

you should look for some a123 battery cells , they have a 31ah pouch cell that does 250amp burst for 1min and the chemistry is lifepo4 so lot less chance of explosion and fire and more importantly these cells are perfect replacement for 12v leadacid and their voltage range is exactly the same. 4 of them in series & 6 or 8 in parallel is all you need to test even the strongest automotive amp out there. i have a pack made from 32700 cells i bought for 50$ and it is supposed to be 12ah 25.6v but it outruns 27ah 24v leadacid in runtime , the pack is powering my ups and runs my desktop computer for almost 2 hours ! and the cells were half the price of buying 6 9ah batteries that my ups use.

Got a 64 AH headway bank that I'm getting ready to put in my car. Def excited for it

I came to figure out the bms part I'm not afraid of playing with the voltage/amperage but I don't like wasting money and time...

Where can I find those end buss plates. They aren't on the list

You should have just thrown them all in parallel and then charged em to 4.2 volts. That’s the best way to balance a pack before putting them in series.

I been waiting for an video like this

Moving up. 🎉

I have def become a battery nut over the last few years. Excellent video hifi

What type of lithium battery Banks? Are they lithium-ion? And another great video thanks. ✌️

Sweet video dude...I'm definitely short in the battery knowledge.

Soooo… did I miss the video? I was wondering how they perform. Im currently researching Lithium to add to my “build” lol. Its ongoing for life😂 but this price point has me anticipating your review, thanks vega!

Great video

How does this work in a car with the alt charging it?

Can a car alternator charge these cells safely

Hey hifi, have you listened to the new sony es 3 ways? I did a build in my civic with them. Id suggest giving them a listen. They are pretty great

I built a battery using 76 of these cells(ordered 80 total but had a couple bad ones)! I did a top balance with the cells along with a small 1 amp charge to them for 72 hours. I’m currently using this bank in my camping cargo trailer. They aren’t being stressed AT ALL even when running my 2k watt pure sine wave power inverter. These cells are awesome! They are rated at 200 amps continuous and 400 amps max… per cell! They are a GREAT alternative to headway cells. Just make sure you buy the correct BMS, otherwise you will have a max battery voltage of only 14.7 volts. Ask me how I know!! Hahaha Great video HiFi!!

Do you have a video showing if using balancer and where to get it?

You've likely seen my little lithium pack 'incident' already. My house currently has about a 7.5KWH backup battery setup, made from 36V 'scooter/E-bike" recycled packs. Was pretty useful when I lost power for 9 days in those Norcal storms. (And all communications for 6 days, and no road for 8.. Fun times!) Good for a couple days of lights, comms and computer/TV power, as well as my CPAP machine and electric blanket. Have some mods planned to run the freezer/refer from it as well, just need to tie in the big inverter. (Everything else is on a commercial grade surplus UPS. Don't even see flickers in the lights when power drops, just my mini-split shutting down..:) Those SiP08 cells and the busbars would likely easily 'dyno' a 10,000W class 'D' amp at 1000A drain for the test duration. The cells each can take a 200A short term load, and you have 6 in parallel. The busbars would hold that current for a min or so fine, they just can't take over 300A long term.. Would double-check that with your build by checking terminal voltage under a short, big load. Bet they'd hold up great at at least 600A for a couple mins or so... Then quite a bit of charging..:) Just ordered a 36V 6.4KWH EV battery to add to the pile. Be careful and enjoy the power! Stu

At full charge my bank is sitting at 16.6 volts. And that seems to be to high for my car. How to fix ?

I want to build my own for the Orion 3k.1DSPLX but I’m not a chemistry kind of guy so I don’t know how many of these things I need

What the update on this battery bank still waiting.

When adding a balancer, does the board on the balancer need to be set to nmc/lfp or lto on the solder points?

"top balance" would be a balance at 4.2 per cell...

I never seen that type of batteries they look more like a regular battery in stead of a bunch of toots rolls bolted together some battery boxes with post you would never no perty sweet deal 🎶🎵💯🛠️👍👌✌️

Stupid question for anyone: why would the original owner replace cells that are still good? (logically assuming that's the way they end up on the used market)

Out of curiosity how many of these you need to make 300 volts?

You gonna show how to do the BMS?

Got another question. What BMS do you use or recommend with the spim cells 96ah banks?

Can a use 2 banks like this for a car system can be charge by the car alternator??

I’m building a 96ah as I write. I have had no luck in ordering bars the last couple weeks. If I double up on stock bars, do you that should be sufficient till I can find some to order? Or just make 2 48ah?

Got my ctsounds pre fab slot ported great price great quality ...installed it and the new xr12 dual 2 from American bass ....but now I have a power issue have enough amp with either the jp23v1.5 or my skar rp1500.1 put the skar back in to see if it would help with the draw off my battery but both amps are now dropping down to 9volts and all but shutting headlights off ....so I have an upgraded alternator but it's nor big enough so ...going to get a 300amp alternator....do you think if I just add a small agm battery like the one ds 18 offers for around 60 bucks will solve my problem or what should I do ...I wanna keep it around 300 dollars and the alternator is 170 .....

Vega what BMS do you suggest and this should keep up with a CAB22 amp correct? Lol i hope so i already ordered it.

Are the battery hookup busbars safe to use for car audio? Also, is a 96ah bank this setup just x2 and 4s6p?

Can I use this in my car it says great for golf carts on battery hook up

Between this and headway,what's best bang for buck,and are the balancers the same,and can either be ran with a lead acid battery as long as an isolator is used,,I keep hearing don't mix lipo4 with lead acid with no explanation..thanks in advance

I smoked 3 of those lil 1.2a bms' until I learned correctly🤣🤦‍♂️ now I got a 10a heltec balancer that was very expensive and would cry if I fried it.😭

Why do all this vs buying the 12v 48ah headway bank for $150?

Do you have to top balance when you have a balancer?

👍

What’s the c rating on this lithium

What voltage does one of these banks need to charge at?

How many watts can that bank handle?

You have to charge these at 16volt anything else you are not really using them to there capabilities
