Car audio amplifiers do not pull a constant current. They pull currents in bursts. So these are perfectly fine for audio use with a large capacitor. It will run 10-20kw amplifier setups fine.
These car audio guys just can't comprehend that the 2cm thick aluminum bars are extreme overkill and don't want to admit that they're just throwing their money away.
@@yasirrakhurrafat1142 the aluminum buss bars only work with cells that have bolts. I don't recommend Aluminum I would use copper it conducts electricity better than aluminum. I actually like his PCB design. Personally I'm trying to save money so I can get some batteries for my bus that I live in but I am disabled and live on a very fixed income and it's getting hot here. The main reason why the car stereo guys use those aluminum buss bars is for looks
@jehugarcia As this is the smallest pcb you designed, do I have to run 32 batteries or can I use 20 or 24 batteries until I can afford more? I live in Trinidad, so shipping that many batteries may kill my budget. Will you be making smaller boards in the future?I really don’t want to buy exsensive aluminum bus bars.
If using in car application do you need a balancing system? Someone had mentioned that it woild cause more of an issue than anything if one sell isnt up where need be. What would be the benefit to using a balance charger or can it charge off of alternator on its own
Just wanna say thank you for addressing the car audio community. We really appreciate the work you've put into these bus bar's. I have the 1st and 2nd gen of the 1000A plates and fixing to upgrade to the 3rd gen. Keep improving and I'll keep buying.!!
I don't disagree, but the temp measurement in the top left shows the hottest measurement on the screen. So you can at least know it isn't hotter than that.
Has any one tested if trickle charging Li Batteries can harm them in any way or be less efficiant , ie; if you have solar but not great, and plenty of time to spare...?
Rule of thumb for headway, 10ah per 1000 watts, so your 12,000 watts you'll want to run 120ah to have sufficient battery available. And keep voltage from alternator limited to 14.6v maximum. And do not put trust into a balancer alone, build a contact relay controlled by a 30a bms so in the event of a power draw the bms will cut power and save your bank from being drained to 0 ruining everything. Need help with it send me a message it's not difficult and worth the additional protection
I'm not familiarised with this PCBway board designs, so my question may sound a bit stupid, but could someone explain me how the series among the 4 cells is done? The design shown has no connexion among cells. Are the connexions done with external wiring? if yes, why so and not through the board directly? probably because of the amperage? Thanks for a short feedback.
There are total 32 batteries, arranged as 4 sets of 8. Each set of 8 is in parallel, and the 4 sets are in series. In each of the two designs (old and new), there's a top PCB and a bottom PCB. Starting at the + end of the pack: [+]--top--[+ Set1 -] --bot--[+ Set2 -] --top--[+ Set3 -] --bot-- [+Set4] --top--[-]. Hope that helps.
When they speak of a stiff pack they mean like back in the date we used to use capacitors as stiffening caps. And what the stiffening cap does? Is. Give them the extra boost of power instantaneous without killing the battery? So what they're saying is they want to use these batteries as a stiffening cap
I can attest that these PCB, the 1000 amp ones, work as Jehu describes. Totally recommend.
Anything can carry 1000A… for a short time.
Having PCBway in the title made me think that they were selling the scam bus bars, ha! May want to rethink that ad placement
Only fools that don’t watch will think that

Aluminium bar for what?
@@yasirrakhurrafat1142 buss bars to connect the cells together to make a battery
@@jamesmason7124 ah.
Is it any better than the tin.. spot welded stuff?
To pay $300 for fancy Dancy bus bars is absolutely ridiculous lol pay the same for bars as what the cells cost.

how about adding PTCs / Fuses or other protective functions to the busbar ? This is pretty rad.
I would absolutely be keen once you have the BMS! Even with the shipping to NZ!😅
Awesome video bro,
How much does this boy cost to manufacture?

Yeah I’ll show you how to make smaller packs with these boards, Others have asked, video this week
@@jehugarciathank u so very much. Love the information u've provided. Thanks much👍🏿👍🏿👍🏿
Very good, 100A power max..⚡👍👍👍
You have to buy more equipment to show us the 1000A!
Another couple of 5kw inverters should do it
My Klein cl-900 clamp meter will read 2000 amps AC and DC , maybe you should get one, it was like 200 dollars at home Depot
@@jehugarcia
Are there also such PCB busbars for super capacitors?
If using in car application do you need a balancing system? Someone had mentioned that it woild cause more of an issue than anything if one sell isnt up where need be. What would be the benefit to using a balance charger or can it charge off of alternator on its own
Used cells will likely differ from each other so they will need a balancer

Where do I purchase the 2awg terminals after buying the boards?
There’s a link in the project page
where are the spot to do a 4s balancer on the purple board with the wire connectors?
Take a look at this video th-cam.com/video/TTtJc1d7JxM/w-d-xo.htmlsi=UaNebgttmbzNYSt1
Great video. But for the thermal camera you should set the spot measurement over the hot spots!
I don't disagree, but the temp measurement in the top left shows the hottest measurement on the screen.
So you can at least know it isn't hotter than that.
I moved the center spot right center of the hotspot a the end of the test
Has any one tested if trickle charging Li Batteries can harm them in any way or be less efficiant , ie; if you have solar but not great, and plenty of time to spare...?
It’s only 100 degrees..
Canadians 😳
Oh yeah you guys still use Fahrenheit
so can these be use for car auido systems or am i missing something? cause i just ordered me an 48ah
Yup, that’s what they are mainly used for in our experience
But the PCB can carring this huge amperage?
Wish there was some way to tell
So if you do 4 of these + to + and - to - what will the total amp hours be?
64ah x4
@@jehugarcia thank you.
Will this 64AH be sufficient for 10,000 watts RMS with an XS Power D5100R and Autotech 290A alternator? Or will I need 2 64AH?
I’m not into audio so I don’t know, all I can tell you is that these cells can do 2000A on a dead short and my busbars can do 1000A
Rule of thumb for headway, 10ah per 1000 watts, so your 12,000 watts you'll want to run 120ah to have sufficient battery available. And keep voltage from alternator limited to 14.6v maximum.
