This is the best system for DIY I saw till now. The most powerful advantage advantage of it is that when any of the cells goes bad, you can very easily replace it and continue use the battery, no need to break the welding and spot weld the whole pack again which is very time consuming and frustrating work. You have to mention this advantage. This battery pack is FOR LIFE, This is the main reason I use your kit over any other battery packs on the market.
This is awesome. I bought one and have now finally assembled most of it. I found the BMS board and the top board have their ports backwards (for the rainbow cable that communicates the voltages of each cell). Maybe this is due to the specific ones I ordered and because I did not do it as one kit purchase.
It is getting more and more simplistic and optimized ... awesome project! ☺️ ...keep working on it. loads of people benefit from what you are doing
Wow… you sold out all the batteries and almost everything... that's amazing RUclips power and community!
The second your BMS's and State of Charge boards come back in I'm ordering a set
got the 10x kit, waiting patiently for the BMS's to come back into stock :) great products Thanks.
Can you please show us how to efficiently charge a battery pack like this?
When you first designed the boards, you tested for heat and they were getting hot. Has that issue been resolved?
I need that in a 4s 12v configuration
Let's see and take 3 lithium cells (3s) ...
3x 4.20V = 12.6V, this is a little bit too low, should be 13.6V ... 14.4V.
And now low voltage (per cell) 3.0V x3 is 9.0V, that is too low for inverters, most of them stop between 10.5V and 11.5V.
Ok, trying 4 lithium cells (4s) ...
4x 4.2V = 16.8V, this is too much for most 12V Inverters.
And now low voltage (per cell) 3.0V x4 is 12.0V, that is ok for inverters.
Even 2.8V per cell (4s is then 11.2V) would be ok.
A better way would be with *LiFePo4* cells, typical cell voltage 3.2V
Depending on the manufacturer the maximum voltage is 3.50V ... 3.65V.
So 4x 3.6V = 14.4V, this is very good, voltage is like AGM battery.
And now low voltage (per cell) 4x 2.5V is 10V, that is a little bit too low for inverters, but with 2.7V it makes 10.8V and could work, depending of the inverter.
But ... using LiFePo4 you will need an other BMS, i think. AND there are LiFePo4 with the same size 18650 in the shops! So after buying you should look at the difference and do not mix them in the same battery holder.
What about the kit.co/jehu/lifepo4-pcb-26650-kit ? YT-Video Kq_5yhZ4P30
Oops, there is already a video about that: Kq_5yhZ4P30
Well, for you 12 volters, it's time to upgrade to 24 or 48 volts. Built my system with the latter, so I would need two of these modules to provide a full 48 volts... which is a far more useful and efficient voltage when converting DC to AC.
so that 3.7V x7 not 4.2V x7 right?
@@jacquesb5248 always the nominal voltage. For standard Li ion it's 3.7 or 3.6. For LiFePO4 it's 3.2.
Or just use LiFe
Wow the best lithuim diy I have ever seen need to order a few
Hi...do you have a vedio for 1s 100 amp lithium iol version protection board...thank you
Just ordered 5x kits 😍💋
Jeff Allen not yet 😊 still on the road😋
Gday mate , love your channel and the awesome projects you have .
I am in Australia and we dont have the exposure to access used batteries like you do in the US .
Do you post to Australia at all .
Keep up the good work mate .
If the bms protection is much higher than the battery discharge (40a bms, 25a battery pack) then how do I get the proper cut off protection?
When are you going to be getting more supplies in? I had a couple of Ebikes stolen last year and have had the batteries (samsung e35 120 cells) laying around and would like to purchase a kit of 15 of these.
You should always keep lithium batteries at a storage voltage. You don't want to store them fully charged, especially lithium polymer batteries.
Hey jehugarcia to charge the pack could you hook it up to a 24volt solar panel?
Beautiful, high quality product! Thank you so much 😊
ever think about doing a back up system build with your pcbs?
Thank you to continue to share your knowledge.
I would love a 12v version of these boards. Trying to make a small 30ish AH power pack right now to run a diesel heater for my camper.
Someday i will be like you, creating and inventing new one.. ❤❤
how do I make a 12volt battery?. is there a kit for that?
Your videos are awesome 👌
I wish you had these in 10S... I wouldn't have wasted money on the vruzend garbage that cracks, loses contact and destroys your hands trying to assemble them. Your boards are a million times better, you just need more options for voltage.
Without soldering in the batteries into the packs it will not perform well, especially on longer term, it can be also dangerous (corrosion, resistance increase at connection points, false (lower) measured voltage values - > overcharging, etc )
They are perfect for a power wall but how do you charge the pack? Preferably through Solar..
Solar charge controller
@@jehugarcia Thank you, are the BMS Populated Board available now?
what we really need are parallel configured boards. the holders are not rated for high current and for ebike applications we need them to be parallel so we can make a pack then by seriesing 10 or 14 modules
These are not for ebike use
@@jehugarcia then what are they for? making 6s power banks?
What's the Amp on them?
How can you buy ribbon cable?
If the internal resistance is way too different? For example I have some batteries with 30mr ve 230mr does that matter? I mean wouldn’t one battery drag the other 6 battery because it has lots more resistance?
Why don’t you connect the ribbon cable to each board when you are stacking them? It seems easier to me...
great videos and always interesting to see your builds. I have the following problem and wanted to see what a battery system configuration I would need. I have a 2/3Kw load that needs to run 24/7. I would like to run it from a battery system that is charged during the day from solar 3kw. What are the necessary components for the battery system and how large needs to be? thx
Hi Jehu,
Can I use a 10x kit as my van auxiliary battery. I will use a step down regulator to get 12v. My question is: Can I use an 12v to 110v ac inverter (plug in cigarette socket) and a 110 v ac charger to charge the 10x battery pack? Thanks a lot for your help.
Thanks for the video. Need to position Camera properly, concentrating on the installation area.
New subscriber here. Thanks brotha! I learn a lot.
All set up, but no power out of the BMS. Checked continuity on all the leads and all the connections. Just will not work. Any suggestions on troubleshooting the BMS?
Check my latest video
@@jehugarcia check my latest email, problem with 1.3 populated board, ribbon connector in wrong spot
Great video. What meter are you using?
Great video!!!!!!!!!!!!!! Thank you.
I like it I need 2 PCB & one BMS total 14 PCS batteries. It works?
Hell, is there any possibility to get this in a 12S configuration, ideally for 21700 lithium-ion cells? That would be awesome for electric skateboards and similar things 🙂
hi, Do you have allready tested to plug a battery pack ( 36 or 48 V ) on a micro inverter ? i have the idea to limit the size and capacity of the battery, with a pv router.
for exemple, use pv and micro inverter from 8am to 8pm and charge battery with over production and discharge battery after 8pm with using micro inverter connected on battery.
Here is a couple of questions if you can answer please
How to make a battery pack from deffirent capacity batteries ?
Does internal resistance really important or capacity?
State of charge. How does that work? I mean there´s no LCD screen or nothing, how do I read the state of charge?
Can you replace a car battery if you build this into a car battery box?
Can you use this kind of set up for an ebike?
How much power can you safely put through these? Could i build a 5kwh powerwall with this setup for example?
Hi.
Is there a way to let me know when you have more to sell?, i need 6 to 10 5x kits
Is it possible to use a balance charger with these boards and no BMS while charging? I think it would make trouble shooting and diagnosing a little easier and enable you to test each board and batteries..
Yes you can
Hey Jehu I know you like drones. The new Mavic Mini uses 2 2400mah 18650 in series. Please modify them to use Panasonic 3500 mAh and see if the flight time improves!!!!! Please !!!!
Using the BMS the charger input and output is on the same cable?
These kits are nice, but kinda limited use if you don't have the BMS boards in stock at the same time.
I need to build a 3s 10p (12V 33Ah) - do you have a battery pack kit for this please. Your kit looks professional and simple to use.
Nice video jehu more power God bless
Was so funny watching this movie, it's a lot of mess inside your brain when you start explaining about amp's and volts and connecting them in series or parallel, I laugh a lot following your ambiguous explanation 🤣🤣🤣🤣🤣
Ha ha. I did this in college and then trade school. I'm still learning about it and I helped build the internet. I even made a serious breakthrough involving high frequency cross coupling of 10MHZ and higher digital signaling across PWB back plains. Who would have thought squarewaves would act like RF? ME. There is no such thing as a true squarewave. Except in quantum computing. There the state changes instantaneously or even prior to the event.
I'm looking to build my first battery pack for my electric scooter.
I believe that this solution here is very practical, saves time and makes things very easy.
But it's not suitable for my project due to the higher costs, think that my battery pack will need 100+ batteries.
It's more bulky and heavier also the batteries aren't permanently fixed in their case so they could pop out.
Can I put this pack on a motorcycle?
So I'm looking at getting some extra batteries installed on my truck to power auxiliary stuff (camp lights radios and a water pump) anyone know if something like this would work ?
Yes. Check out his hard case battery box.
Jehu do you send your products to Poland? if not can you open store on amazon?
Basically anywhere to Europe?
These packs can be put in series? Thank you
Can those kits are easy to make ebike battery? Like 48v or 72 volt
Is there a video showing the complete setup as used in something like home applications?
In the works
@@jehugarcia Bought a kit, im have it all setup. However, i'm not sure how to charge the pack... Not much clear info on the web about using these specific BMS boards to hook into a charger.
Jehu, Nice videro to understand easily. I understood that the output is from the top BMS through a XT60 connection I am not sure where should be the input given. Through the bottom board or any board?
Just a simple question on the 5x kit : with the BMS added, are all the 35 batteries indiviually monitored ? So you can detect either one cell that would fail ?
This is what I'm trying to wrap my head around. Looking at the schematic, the BMS is connected to each cell in each board, but each board connects the cells in parallel for the BMS. For example cell 1 board 1 is connected in parallel to cell 1 board 2, 3, 4, & 5. So I'm not seeing how it monitors each cell individually, that, and the BMS is only for 7S.
Jehu, working on my 10x and 5x kit. Using your BMS kit as well. When does the output from a solar charge controller connect to the battery? Somewhere on the BMS?
Great video, how would I get this 24 volt to a 12 volt inverter ? Would I have to use a step down converter. Thanks
Hi Jehu, I am planning to build a 10KW/H power wall. Is there a way to get a consulting service from you? as well as the quote for needed components. Thanks
Think this would work for an electric mountianboard?
Like work it handle jumps and not dissconnect?
I did something similar and i had issues after a while due to vibration making the batteries come loose.
Hi Jehu, some time ago i bought PCB 25X to build a 48v power wall. please let me know how many BMS units you recommend and SOC units. so that i can purchase it separately. thanks. prem
1 bms board per every 1200w of load is recommended. You’ll need 2 of you are going to run two stacks in parallel for 48v
how do they get charged up
This is awesome, is it possible to get a system like this for 4s because 7s is too much for my own application.
Can thies pcbs be used for a 12v pack?
No
Love the vids
I need an inverter. I see on jag35.com that you have a 3000w inverter which is 220v output and 24v input. This would be perfect, but I need 3500watts. I need to pull 14 amps at 240v to operate my car charger safely. Any suggestions?
I only have a 12 volts system, I cannot use anything above 14.1 . As interesting as these may be they cannot be used on a 12 volts system. Thanks for posting anyway.😁
Dart Gar you can use a step down voltage regulator, if you want to.
Or you can use only 3 cells, instead of 7.
Thank you so much for the info I will plan for it then.
top show dream of consumption :)
I'm your fan :) Spiration to make supports
I have a Bms of 60A, how many amps can the battery make?
I need 48V, if I buy the 10x kit + a spare BMS, can I run it in 2x5 configuration till I can afford a second 10x kit to run 2x10 ? I'm asking because the ribbond cable is not modular so I think I need also 2 'x5' cable that will be throw away after. If BMS work for both kit I think it's doable but would like a comment from Jehu himself.
I have a solution for the ribbon cable.... working on that next..... video coming soon, maybe tomorrow
@@jehugarcia how many 7s pcb the bms can manage ?
does populated mean with batteries. way too confusing to figure out pricing.
Does each pcb come with a bms
I am looking to get rid of 40 of these boards that I got from Jehu's Website. I don't know where else to market them because people don't know what they are or how to use them other than Jehu's audience. They are all already built, just need to add batteries. Let me know if you are interested. Thanks!
I would be interested
@@MrBenbrown2008 Okay im on all the social medias, so you can contact me at one of those
When are you going to start taking orders for battery cells already made for us too stupid or scared to do it ourselves???
Never, too many restrictions and too much liability in a suing happy society
@@jehugarcia sucks...but I understand.
@@jehugarcia
Do you think liability is the main reason why there are no reasonably priced lightweight racecar starter batteries for ICE powered cars?
Everything I've seen in this battery class starts at $1000 and goes up from there
www.jegs.com/p/Altronics/Altronics-Powerlite-16-Volt-Lithium-Batteries/1528620/10002/-1
I don't get it. A Prius Hybrid battery has much more capacity and is around the same price.
@@brad3378 liability plus raw materials then the co needs local,county state and federal epa permits
one example buffet built a factory in china/ 1 agency to deal with and from plan to first product 6 months. in much of usa it takes up to 2 years in many cases dozens of permits sometimes even when you using existing building not impossible but takes lot of time money and lawyers.
assembling battery packs is a little easier but you need a lot of production to make money
Where i can get this battery modul outside US?
Great video Once the BMS is available again, how can I monitor the BMS with a computer or screen, what is the item I need to view what it going on? I know you have the SOC module but I was looking for a way to monitor this remotely or connected to a computer. Is there a standard for that BMS ribbon cable interface?
Anybody? How can I add a monitor, preferably a wireless monitor to this? I saw some that have Bluetooth modules. How can I add a Bluetooth monitor to this BMS?
@@johns2590 that will ask a lot more €€ or probably in ur case $$
If I was to connect my charge controller from my Panels to the BMS board, what would be the best way to do that? Could I just use the two larger holes?
What's the difference between single stack and double stack boards like the ones in the gas can?
Is it possible to put each of these plates vertically attached to a wall? One on top of the other and complete each plate with 28 batteries, soldered in packages of four each of the seven holes? Greetings
What happens if u accidentally put one cel in opposite direction? .. whn i was making diy powerbank so ordered pcb and case and i put all battery in it bt by accidentally i put only one battery in reverse terminal and what happened , pcb burnt and I quickly removed cell and that’s how i fired my newly order pcb
I have 6 of those valence green batteries in a 24 volt setup can I use this battery setup in conjunction with my my lifepo4 green batteries
Going Green🔋/BMS/PCB👍
Love your videos ..... I live in Canada, and would like to order ..... why ni cdn shipping.
Hey, just placed an order for two of these 5x kits, but sadly the bms module unit is sold out. Can you please give an update on when they will be in stock or a replacement that will work on two of these kits in parallel. Regards.
Is it possible to recharche this battery pack straight with a solar panel, maybe just with a MPPT solar controler ? If yes, do you recommend an mppt model ? Thanks.
Would like more info on how to DIY Powerwall for home use. Have seen the boards you show on online China websites are these the same as the one you sell?
The Chinese boards are exactly the same that’s where he gets his from if you look on Wish you can buy them on there and they are 100% identical
where can i find info on the circuit boards. how do the bms lines work.... is there an app for the bms ??
Hi, i am trying to understand, is each cell of each board monitored by the BMS en top ? thanks for the information.
How would you charge these packs? I'm looking to do this using solar where would I connect the solar charge controller?
This PCB is designed by you as per you professional experience right? Like it very much, it makes DIY much easier!
No, Jehu is not an electrical engineer, he is an enthusiast like us, BUT from what I understand he did not design this board alone. He essentially did the basic design and an EE in the EV community made the real PCB design files and double checked it at that point. I wish I could remember his name to credit him.
@@kingrpriddick Cual es la pagina de esa comunidad? Quiero armar un pack de baterías como estas para mi casa. Soy estudiante avanzado de ingeniera eléctrica, pero recién este año estoy viendo baterías. Saludos!
We can find clones everywhere on aliexpress now.. hard to tell if he's reselling that or if he created it. Let me know !
I started to put it together but one of the PCBs is not working. It is missing a small fuse (I think) that all the others have. How do we get a replacement?
Why Do you need so much PCB
You can never have too much PCB
