This is exactly what I’m looking for. Lots of 12v power. Perfect for camping. I bet I could use this without charging it all week. All I’m using it for is to run my CPAP and charge handheld devices.
Jehu, a power wall kit like the 36v version but 48v would be great.
Keep uo the good vids Jehu!!!
Jehu, Connect the top layer and the bottom layer using a larger amount of Via.
Then you can further reduce the resistance of PCB connections.
Awesome!
Just noticed your channel a few days ago. Love the contents.
I build normally using 32650 for a few reasons.
1) its cheap. 1-2$ pr cell. And im poor.
2) you can somewhat shape them if you have space for a battery that isn't perfectly box shaped. It gives some option with tight spaces.
Do you have some cool prints for 32650? I use cooper tapping wire but a nice pcb with leads for 2-3 5a balancing & a bms connection would be cool.
Those cells are bad ass. They would be very useful if you could design a mobile tool cart for mechanics with a 4s6p battery pack at the bottom to have lots of available power, plus a 2Kw inverter for plug in only stuff. The extra tools could be jumper cables to start dead cars and a small compressor and air tank to fill tires and have compressed air. Plus you could charge battery packs for whatever electric hand tools you use. Lots of people use Milwaukee. You could also hook up a car stereo with an efficient amplifier for some tunes while working outside or wherever you have your tool cart. I almost thought it would cost to much to build until I saw what companies like Snap On and Mac tools charge for empty metal boxes and carts with no extra usefulness built in.
If you hava a 2kW inverter, 24 or 48V is a better option..
8S3P would be a better option. Also 24V DC equipment is readily available due to trucks using 24V.
What kind of design software are u using? The Lev60F arent available in Belgium so i have to adapt the board to the larger ones. Thx in advance!!
would these be a good choice for an extension pack for solar generator
What software do you use?
this is what I am looking for If I can get the pack to fit, what BMS would you recommend?
Do you have a link to that battery cell monitor?
Seriously How good are these for car audio.... are they better than headway cells or spim08hp cells?
Is there a link for those terminal blocks?
شرح ممتاز جدا
I made a 72v battery pack for my ev with the Samsung version of them (40ah)
👍👍👍
The battery cells expand and contract during charge/discharge. Will a pcb last long term with these movements?
Its neat and very good looking.
I will be making compression hardware for these cells
Does the PCB come with the green balance connector attached to it?
First ones didn’t but now they are shipping with it soldered on
Just curious where I could find the battery terminals and easy bms hookup
In the project page
Awesome thanks for all you do sir
I bet if you made these for the EVE 280ah cells from 18650 battery store a LOT of people would love to purchase them. They have a pretty unique kind of terminal lug though.
I might have already designed that board many months ago but I never released it because the cells I ordered took forever to arrive, I think they are 280s I just have to check if they are same dimensions as thr EVE cells. Is that seller reliable?
@@jehugarcia I have seen tons of videos with those particular cells being used. Currently the 18650 store is sold out of them but there are several other stores that do have them. Having a board like yours would greatly simplify the assembly - especially when you make it so simple to attach the BMS.
The McMaster link is for M8 nuts, however the parts list says M6. Which is it? Thanks
M8 x1.25 is the correct size
what is this batter specifically for? is it for car stereo or car startup ? or both possibly?.
Both, they are also priced well to be used for storage applications
@jehugarcia thank you, your not so far from my area I would love to talk to you about many projects that I want to purchase batteries from you but I'm not an expert like all you guys hehe, if I knew more I would be buying way more.
I need a compression kit for 12 v lev60 bank your sold out when will you have more
Sometime this week, they are selling faster than I’ve been ordering them but we are getting some this week.
Can this use for bigger cells like 280 amps cells?
Only if cells are same dimensions
In the past you used to say that bms were the weak part of the battery, what do you think now ?
They are better now, but they still kill a lot of battery systems, most of the time bms is what’s wrong in a faulty battery pack.
@@jehugarcia i am designing a 12 volt battery pack much like this one and I am thinking of by passing the use of a BMS, am I wrong?
A well matched set of LiFePO4 cells should be fine for 10 + years without a bms. But it’s a bit of work as lifepo4 cells quality is terrible. About 5% of them divísate enough to cause problems
So how long did the battery pack last under all that load?
About 20 mins
@@jehugarcia Great, thanks 👍
Is there a lithium solution that would be able to start 3l tdi engine. Would be safe to replace agm battery. Thansk for any suggestions
These batteries in 4s configuration is more than enough. I replaced the battery in my 2015 vw golf tdi with a battery he offered a few months back called the slm121 which he has been long sold out by now.
@na hanky issue is that in UK it's hard to get them. I usen now upgraded egm. But would love go for my sq audio system with lithium
@@ealneas1 I gotcha, I'm sorry to hear that it's much harder to attain over there. That's precisely why I upgraded to one of his lithium batteries. I'm running 3500 watt sound system and my two agms and high output 370a alternator weren't keeping up for some reason. That one single battery outdid the two agms though. I hope you can find something that works for you. I wouldn't use anything other than lifepo4 in my car though that or LTO( lithium titanite oxide) which are fairly more expensive. To answer your question though. These lifepo4 batteries are perfect for regular car batteries replacements.
Do you make boards for 48v
Really?
@@jehugarcia how about 100S for 320V nominal 😜
Is each one of these cells 1780w for 49 dollars? So 4 of them is 7120w? Excuse my ignorance, I am new to this and planning battery backup for my house later this year
74ahx 3.2v = 236wh x4 = 947wh
I heard you say the battery is 4.2 volt but specs say 3.2. Am I missing something?
That’s a mistake
@@jehugarciaif I charge at 14.4v I’d need to go a different route huh?
Could i use this on a taramps smart 3 car audio amp 3000 rms
You can use this battery on any 12v amplifier
@@jehugarcia nice my amp is rated at 12.6v I think I want one .just need the compression kit . 200 for a bank that will push my 3k ..cool I'll be buying one
Can I run a 1300 watt amp on this battery
Yes all day.
14:44 it’s 153 degrees F. It clearly shows the lowest and highest temperature on the left of the screen. You adjusted and pointed the sensor at the middle of the pack shortly after you started the second test. You should have left it pointed at the actual connection point. I feel like you’re trying to deceive people. Or you just “happened” to “accidentally” adjust the thermal sensor off the connection point as soon as the temp started rising above 120F. I can see why the audio guys give you a hard time. It would have been nice to actually see the true results.
Oh yeah in trying to deceive people by showing you thermal tests, I just need 30 degrees to fool people. The audio folks trashing my boards sell competing aluminum bars so anyone with half a working brain can see their motives.
Name of this battery pack please
Dude these are continuous loads also. It's actually insane how cool it stays under a continuous loads like that. Music is not continuous and only pulls the amperage when the bass hits. A music system because music is continuous is never going to pull its peak at all times.
yeah second test you failed hard and you know it didnt even have it targeted correctly
