Since this is my first go around with a lithium bank I am sticking with the headway cells. But this s awesome to the variety is there to everyone interested in doing this.
You DO NOT use a drill/driver to put on the nuts for the cells. Each should be torqued and it's a small number like 5-7nm. The studs are normally a soft metal and can easily cross thread or break off. Not something you want to deal with to save 5 mins of assembly time.
Of course you can use a drill ding-a-ling.. maybe if you don't know what the hell you're doing and you don't know how to use a drill then maybe not but any man should know how to use a drill
When working with lithium cells you should always cover up the opposing side of the bank. If something fell between the negative and positive your gonna have a huge fireball with liquid metal flying everywhere. Ive seen it happen.
Hey bro, how can you get the most out of this cells if the pack become 14.8v nominal and 16.8v when fully charged but alternators on cars just go up to 14.4v, mine is a 320amp aftermarfet alt and i am getting 14.4v out of it, please help me understanding how would you do it or if anyone have an idea that would be great, thanks
DC-DC converter. The guy in this video didn't really explain the 14.8v nominal rating very well. The voltage in lithium ion batteries goes up or down based on their current state of charge. Typically, a fully charged 4S (Four cells in series) would have a fully charged voltage of 16.8v (4.2v/cell). A fully dead battery would have a voltage of around 10v-12v, depending on the specs of the batteries (some cut off at 2.7v/cell, others as low at 2.5v/cell). Nominal voltage of 14.8 is basically a reference voltage that is essentially a 50% charged battery because saying it's a 12v-16.8v battery is a bit awkward. So when you say 14.8v you know it's a 4S setup that ranges a +/-. His reference to resting state isn't really accurate. Since your car battery is 12v and your alternator is 14v.... Yet the battery pack can be between 12v-16.8v, you'd need a DC-DC buck boost converter. It basically takes the input voltage and outputs whatever you want. Some are variable where you can turn a dial to set the output voltage, others are permanently set. So you'd hook the output of the battery pack to a dc-dc converter set to output a steady 12v or whatever you need. As the battery pack voltage changes as it discharges, you will continue to get a steady 12v output. The tricky thing here is that a 4S battery pack needs to be charged at 16.8v. so if you want to charge your battery pack from your alternator, you'd need another DC-DC converter going from your car battery to the battery pack stepping up the voltage to 16.8v. So DC-DC from car battery to battery pack @16.8v. Then DC-DC from battery pack to your amp @ 12v or whatever you need. This does start getting tricky where you could have an active load on the battery while you are trying to charge it. This is generally not recommended unless you have a proper power management system that can prioritize power flow, unless you have enough alternator output current to charge a dead battery pack + run your amps at the same time. Of course you'd need be sure current is limited and the battery pack is charged properly with a CCCV method (which a good DC-DC can do). I only skimmed the video so I don't fully understand how these batteries are going to be used but is say charging the battery packs from your car alternator is a bad idea.... This probably should be charged separately and just used as a mobile power station or something.
Bro the name brand batteries are a complete rip off and thats why they wont tell yoh the exzact cells that are in them . I havea 148ah lev60 bank i build for under 300$ and will continuously put out 600 to 800amps .

This would be like $5000 if it was xs power

Looks like it was on the lowest setting. I sent mine with my m12 Milwaukee impact and it was fine 🤷♂️ All he’s doing is running the bolts down.

I used my dewalt impact 😂@@thelifeofriley815
Great batteries! Wonder where you got the idea 🤔😂
were do you get those terminal connectors
Do you have the description for the product source and location for this lithium bank build?
Where I Can find the compresión kit
And balancer
How would you set this up in parallel?

That's true for any battery
Omg the breathing through his nose is making me rage 🤬
Yooooooo
Take your pills.
Came here to say the same shit lmao
We can tell this comment was left by a woman.
@@SacredHeart0520 nah bro my username/email is my daughters name lol im a guy swear haha
Where can I find these
Battery hookup 👍
Where did you get the active balancer?
Sriko batteries
How many watts can 160Ah bank support?
14,000 or more
14,000 or more
These batteries are from Chinese busses and can get from battery hookup
Did he really pull the power drill out? Wow
And you should always unplug your balancer when hooking it up, that's a easy way to smoke it.
How many of these cells make 300 Volts ?
100 of them in parallel
Moving on up nvx
You should do a Cmax battery bank build. They are way more popular
Way more expensive as well.
Lol don’t play me, I see your prices you can afford to build one 😂
Why would you need this for car audio

You install Diodes on the alt sense wire to raise charging voltage

Please teach me literature
