I just want to say I really appreciate you sharing all of this information with us. In addition to just selling a product that makes life easier, you always take the time to educate which I 100% appreciate.
If you can't beat them join them! You can mass-produce these and be the middle man to audio stores. Have them pre package with your name or brand on them. I can see these on the shelves of my local audio store
You should definitely use a hydraulic crimper with those ferrels. The resulting difference is massive and is equivalent to the strands fusing into one after proper crimping, which is important for longevity especially in the trunk of a car and for minimizing the resistance in the connection.
There are differing opinions on whether large ferrels should be crimped. Crimping it is going to make it out of round and when you install it in a lug, like on an amplifier, it will have a tiny contact patch. What good is a massive connection between the copper wire and ferrel if the connection to the amp is poor? On the other hand, doing it like in this video will at least maintain the bottom 50% of the ferrel shape. So you'll get better contact with the lug. Whichever you choose is up to you.
I like them better with out the terminal . I use these in all the audio installs I do I think they look better than the thick aluminum bars but that’s just my thought
Is there a how to guide for folks who want to use the 500A version in a car audio/ secondary battery set up? I’m specifically wondering what I need to do to the headway cells prior to installing your kit. (I bought the 500a).
Nice stuff. Id buy it just because its pretty and oversized haha now.. where is the expansion daughterboard for the serie connected 3500 farad supercaps to hit 50.000 amps burst?
I am brainstorming how to do this but build a 72v 5+kWh system for my motorcycle. 300A with 500a surge. I was thinking of of using copper. But now I’m wondering if I should just cut down buss bars like this. However I’ll still need to end up at 14s
It makes no sense to cut these pcb boards down. Plus 2oz is quite thin, 0.002". If you use 1/32" copper sheet that is 0.030". It's way thicker and way cheaper, but you still have to cut it out and drill holes, etc...
@@JasonWW2000 yeah, you are definitely right. If I wasn't so lazy I could also just design my own to order that would meet my personal design parameters too.
Hey bro I like your videos I don't have any problem with them they're very educational mind you I have not tried any one of your DIY projects as yet but I really do like the Headway sales 12 volt battery that you make I am thinking about trying to make one myself but I am in Jamaica so you know I'm not sure if I can get all the parts in Jamaica here
Any info on the lg chem 60ah cells? I know you said a shipment came in. Haven't heard anything else. Purchased mine in beginning of February. Just curious, thanks jehu.
Dear friend that's a totally new item for me we need to run a battery system for off grid type use to run home appliances by charging solar panels is it workable for our need to use a few fan refrigerator etc i thanks in advance for your kind advice Rgds Noor Habib Afridi
So 36 would be rated for 1000 amps potentially. I have a bank of 84. 21s4p 168ah. So that should be close to 2500 amps. Ive always heard that adding another 0 is close to the wattage that it can handle. That would mean my bank should be able to handle close to 25,000 watts. Is that correct? Just doesn't seem right. Lol. I'm running about 15k watts and never drop below 13 volts tho so maybe it is close.
Do you need 1000A of power? I suspect you don’t so you would be better off using the LEV60 packs jag35.com/collections/new-arrivals/products/fully-assembled-12v-lev60f-battery-lifepo4
@@jehugarcia no, I just need a 12v of 100ah to 150ah (200ah max) in such a modular built setup? Packed in small, like inside a waterproof junction box. One of your videos has what I need for my application
I have a question. I am a Bass Head enthusiast, and I'm running 4/0 welding cables coming from my 408 amp alternator. so I wanted to know can your wire distros can fit a 2/0 gauge wire cable?
Most all car audio guys are going to be using multiple runs of 1/0 wire running to the battery. If say a 7500 watt amp wired to .5 ohm has 3 pos/neg hookups most will run adapters to run 6- 1/0 cables for positive and 6 for negative. And there are a lot of amps out there that are a lot bigger than that. And then you might have 2 or 4 sub amps just like that. Then you have amps for the mids and highs which also require there own lug. Then you need multiple runs of wire from the alternator to the battery. Before you know you have 12- 1/0 wires going to the positive and 12 to the negative. Thats why car audio guys need those big bus bars with a lot of connection points. Not to mention your starving your amps of juice if you have a 2 guage connection. Lots of videos showing on a dyno the huge difference in power it makes
Where can i buy that from you... Thank you for saving us car audio guys so much $$$🎉 beware seller's of expensive bussbars will be VERY upset n hating on you but hell with them theifs
Very interesting videos about these bus bars, I have two super beasts from battery hookups that I use zero gaze wire for my connection I run them in parallel with two 4s balancers but I want to change all that to that purple busbar how can I order one from you, your reply much appreciated.
Are you asking? Jehu is not going to do it. It may be possible, unfortunately I don't know anything about the leaf battery. It may not operate unless all its bms wires are connected and working.
You can't really get 12v with an 18650 cell. You can do 3S and be below 12v or do 4S and be above 12v. The other issue is how would you connect an 18650 cell to a pcb. They don't have threaded ends. The device your looking for is called an active balancer. A BMS has lot of other stuff.
I've seen audio guys installing these with no BMS, only a balancer. Makes sense cause the loads they are pulling are beyond the capability of a BMS. Just wonder how they are protecting the cells from over/under voltages. I have zero use for a battery of this type, but I still want to build one.
Just don't over charge them, make sure your alternator voltage isn't going above 14.65. They can sit for a year and not self discharge under safe levels. It's really not that big of a deal. Even if they're discharged extremely low, they can be recovered with a slow charge. They also are some of the safest lithium out there. Unlike cmax cells.
You control the over voltage through your alternators voltage regulator. You control the lower voltage by watching the voltmeter as you use the battery. If it gets low, start up the engine.
why not an alternate version that is 8 wide (with the terminals between the screw terminals)? Then you could get 7 on one side, instead of 5 aimed 3 different ways....
Finally more copper! Now for a demo of them pulling 500 amps through a 1k amp board and see if it can handle it without heating up all crazy. Great stuff, but imo theyre still overrated as far as amperage. (Per your own demo when a small pull for s few minutes heated the board up a lot) Id half the rating and not worry about people being upset about the heat build up, as any heat isnt ouput its just a heater at that point. Even thin diy aluminum bars arent going to heat up like the 500amp board did in your video, thats my only gripe about it. Other than that these are great, i might actually grab a 1k one for testing purposes now.
Crazy? After running 500A constantly for a whole 5 min straight, 50 degrees C/122 degrees F is barely even hot for metal. You can literally put your hand on it, and not get burned. 😂
What would happen if an electromagnetic pulse occurred and burned all the electronic boards of these lithium batteries? Would they be ruined? Can they not be used? Is there any way to protect them from these phenomena?
The only boards he showed in this video was the red BMS board. The delicate circuits inside the bms might get damaged. If you are around massive pulses then you could shield it. As far as the green and purple boards they should be fine.
I'm building a little 64aH pack myself. 4S8P. It is only 2 cells wide and 16 long, so skinny and long to fit my space. 1/8" copper buss bars. I'll probably nickel plate them. Battery box made of 1/4" ABS and bolting them down.
