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.
It is getting more and more simplistic and optimized ... awesome project! ☺️ ...keep working on it. loads of people benefit from what you are doing
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.
Wow… you sold out all the batteries and almost everything... that's amazing UA-cam power and community!
The second your BMS's and State of Charge boards come back in I'm ordering a set
Can you please show us how to efficiently charge a battery pack like this?
got the 10x kit, waiting patiently for the BMS's to come back into stock :) great products Thanks.
When you first designed the boards, you tested for heat and they were getting hot. Has that issue been resolved?
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
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
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.
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.
Hi...do you have a vedio for 1s 100 amp lithium iol version protection board...thank you
Hey jehugarcia to charge the pack could you hook it up to a 24volt solar panel?
Wow the best lithuim diy I have ever seen need to order a few
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 .
You should always keep lithium batteries at a storage voltage. You don't want to store them fully charged, especially lithium polymer batteries.
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 )
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?
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.
how do I make a 12volt battery?. is there a kit for that?
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.
Beautiful, high quality product! Thank you so much 😊
ever think about doing a back up system build with your pcbs?
Just ordered 5x kits 😍💋
Jeff Allen not yet 😊 still on the road😋
Hi.
Is there a way to let me know when you have more to sell?, i need 6 to 10 5x kits
How much power can you safely put through these? Could i build a 5kwh powerwall with this setup for example?
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?
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?
How can you buy ribbon cable?
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.
What's the Amp on them?
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
Thank you to continue to share your knowledge.
I like it I need 2 PCB & one BMS total 14 PCS batteries. It works?
Why don’t you connect the ribbon cable to each board when you are stacking them? It seems easier to me...
These packs can be put in series? Thank you
Using the BMS the charger input and output is on the same cable?
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 !!!!
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 🙂
Great video. What meter are you using?
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.
Can you use this kind of set up for an ebike?
Someday i will be like you, creating and inventing new one.. ❤❤
Can I put this pack on a motorcycle?
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?
Your videos are awesome 👌
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?
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.
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.
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
Where i can get this battery modul outside US?
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
Can those kits are easy to make ebike battery? Like 48v or 72 volt
Great video, how would I get this 24 volt to a 12 volt inverter ? Would I have to use a step down converter. Thanks
These kits are nice, but kinda limited use if you don't have the BMS boards in stock at the same time.
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
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?
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.
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
Thanks for the video. Need to position Camera properly, concentrating on the installation area.
New subscriber here. Thanks brotha! I learn a lot.
Jehu do you send your products to Poland? if not can you open store on amazon?
Basically anywhere to Europe?
This is awesome, is it possible to get a system like this for 4s because 7s is too much for my own application.
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?
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
Love your videos ..... I live in Canada, and would like to order ..... why ni cdn shipping.
Just built my first pack last night. Went to charge it and it tries to weld the XT90 leads to the alligator clips. Polarity if fine. Is this normal. Also tried to add the battery balancer on top of the bms to see how the cell were but it only showed 3 cells
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?
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
where can i find info on the circuit boards. how do the bms lines work.... is there an app for the bms ??
I have a Bms of 60A, how many amps can the battery make?
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.
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.
nicely kit battery, how much , can i buy u 5 kit box ?
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.
Great video!!!!!!!!!!!!!! Thank you.
How would you charge these packs? I'm looking to do this using solar where would I connect the solar charge controller?
Is there a way to get more power using different battery , I want to do a E BIKE battery pack of 87V 50AMPs ?? like 3 in series 20 in parallel, 60 kids in total
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.
how do they get charged up
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 ?
May I take a 12v 100AH battery and connect it to a converter DC 12v to AC 110v, and then connect it to my 110v electric motor to make an electric ATV? In other words, could I have 100AH and an increased voltage of 110v and use on a motor of 110v.
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.
My 1350va UPS runs on 2x 12v9ah batteries in series for 24v...one set of 5 here obviously makes 24v...could this be used as a drop in solution with the battery management module? What performance impact could I expect?
What is the worst case amps that can flow through a Shorted Cell, when these 7S1P pack are then connected in parallel? There could be a ( 5 amp ) Main Fuse at the Voltage Output terminal PLUS there are ( 7.5 amp ) PCB Trace Fuses on the balance leads. So, the steady amps through a shorted cell can be 12.5 amps = 5 amp Main Fuse + 7.5 amp Balance Lead PCB Trace Fuse?
Nice video jehu more power God bless
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
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.
Hi, i am trying to understand, is each cell of each board monitored by the BMS en top ? thanks for the information.
So what do you recommend for charge and discharge parameters I have bought eight of the 7S 10 parallel kits from you and I want to try to make them last as long as possible I have them installed on a small power wall inside my toy hauler camper and I’m using them to run the lights an air compressor Chinese diesel heater and everything else that I need I have 600 W of solar on top of my trailer and then I have a shore charger just in case
Thanks
Does each pcb come with a bms
Hi, do you have or can you suggest a "HIGH ah 12-volt" easy to put together 18650 battery kit without any soldering or very little soldering !
Why not 8s? What is the magic formula to make a 24v system that can put out 100ah like a battleborn? Thanks! Treb
Hey Jehu, hey how’s it going, been following you for a year now, very interested in what you do! I’m having trouble making the connection, for charging and discharging, this has held me back from purchasing, so the xt60 connector, is there a like a connector extension, so I can charge my cellphones, I just haven’t seen those on your sight, and is there a wall adapter that goes to a 110v to recharge the pack? I would like to directly email you, just don’t know how to go about it! Looking forward to hearing from you! Thank you!

Having problems finding affordable 18650 cells at 3Ah. Suggestions?
does populated mean with batteries. way too confusing to figure out pricing.
Hi, it is better than spot welded 18650? or more expensive to use that PCB?
