It is getting more and more simplistic and optimized ... awesome project! ☺️ ...keep working on it. loads of people benefit from what you are doing
got the 10x kit, waiting patiently for the BMS's to come back into stock :) great products Thanks.
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.
Beautiful, high quality product! Thank you so much 😊
ever think about doing a back up system build with your pcbs?
Wow… you sold out all the batteries and almost everything... that's amazing CZcams power and community!
When you first designed the boards, you tested for heat and they were getting hot. Has that issue been resolved?
The second your BMS's and State of Charge boards come back in I'm ordering a set
Wow the best lithuim diy I have ever seen need to order a few
Thank you to continue to share your knowledge.
New subscriber here. Thanks brotha! I learn a lot.
Your videos are awesome 👌
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
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?
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 .
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.
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?
Using the BMS the charger input and output is on the same cable?
How much power can you safely put through these? Could i build a 5kwh powerwall with this setup for example?
Hi, it is better than spot welded 18650? or more expensive to use that PCB?
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.
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?
Hi, i am trying to understand, is each cell of each board monitored by the BMS en top ? thanks for the information.
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?
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?
Why don’t you connect the ribbon cable to each board when you are stacking them? It seems easier to me...
Hi, i don't know if it's the right place to make this question, but i want to make my ''first'' professional 2kw powerwall using 18650, but i'm worried about the safety of this project.
It's the first time i build a battery pack with hundred of 18650, i don't want to connect 100 batteries eachother and have trust only in fuse wires or BMS, so *is more safe to make maybe 10 pack of 15-20 battery with smaller bms (50A for example) all in parallel? Or the BMS in parallel can have conflict?*
The place where all the pack will be can handle the explosion and fire of 1 pack of circa 15 batteries, not 200-300.
Thank you very much :)
Great video!!!!!!!!!!!!!! Thank you.
Hi.
Is there a way to let me know when you have more to sell?, i need 6 to 10 5x kits
How would you charge these packs? I'm looking to do this using solar where would I connect the solar charge controller?
What's the difference between single stack and double stack boards like the ones in the gas can?
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.
Great video. What meter are you using?
Hey jehugarcia to charge the pack could you hook it up to a 24volt solar panel?
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?
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.
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 !
Someday i will be like you, creating and inventing new one.. ❤❤
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.
Great video, how would I get this 24 volt to a 12 volt inverter ? Would I have to use a step down converter. Thanks
Love the vids
These packs can be put in series? Thank you
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
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 🙂
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
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
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
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.
Nice video jehu more power God bless
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
Is there a option to use is with 82V? When yes how many A can I use with it?
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
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
Can you please show us how to efficiently charge a battery pack like this?
where can i find info on the circuit boards. how do the bms lines work.... is there an app for the bms ??
hey.. bro.. i have a question.. i have setup a 12.6v battery pack with 18650's. and i have a bms on it.. those cheep china ones.. and they do cut off at rated voltages.
so to charge the batteries, should i use a charger exactly with 12.6 volt?.. i have a 15v smps laying around.. and i have this doubt , since the bms always cut the battery charging at 12.6 volt, it should be oke to charge it with 15 volt , right?
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.
Where i can get this battery modul outside US?
What PCB software do you use?
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?
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?
I have access to 100 packs of this GS-1907(R) globaltek batteries can i use them for you setup ?
State of charge. How does that work? I mean there´s no LCD screen or nothing, how do I read the state of charge?
how do I make a 12volt battery?. is there a kit for that?
Hi Jehu, can I pair a nominal LG 3.60 with a nominal LG 3.70 LGDBB31865 and LGDAS31865 ?
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.
Are shippings available out of us also?
Can you use this kind of set up for an ebike?
Why not 8s? What is the magic formula to make a 24v system that can put out 100ah like a battleborn? Thanks! Treb
Can you replace a car battery if you build this into a car battery box?
I like it I need 2 PCB & one BMS total 14 PCS batteries. It works?
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, i got the HP module, do i have to use batteries with same capacity in the upper and lower slot? or do i only look for same capacity in each of the 7 series cells?
Yeah you can do difference capacity in opposite side of the board
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?
Any 12 volt build with parts ? 100 amps ? ie RV battery
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?
Having problems finding affordable 18650 cells at 3Ah. Suggestions?
Can those kits are easy to make ebike battery? Like 48v or 72 volt
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 ordered 5x kits 😍💋
Jeff Allen not yet 😊 still on the road😋
Hi...do you have a vedio for 1s 100 amp lithium iol version protection board...thank you
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 )
Can you hot glue for the xt60 ?
I have a Bms of 60A, how many amps can the battery make?
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
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
What type of cell fusing is built in.
Thanks
Can I put this pack on a motorcycle?
These kits are nice, but kinda limited use if you don't have the BMS boards in stock at the same time.
Are there 12v module kits available instead of 24v kits? I need 12v for Amateur radios...
You should always keep lithium batteries at a storage voltage. You don't want to store them fully charged, especially lithium polymer batteries.
Jehu do you send your products to Poland? if not can you open store on amazon?
Basically anywhere to Europe?
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 ?
top show dream of consumption :)
I'm your fan :) Spiration to make supports
Does each pcb come with a bms
How can you buy ribbon cable?
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, 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!
Dean
What's the Amp on them?
I need a 3s version 5 or 10 stack pls help
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 $$
