I am searching a bms connection video in youtube across near about 20 video I found your video are best so thanks solve my problem
After searching through 9 different tutorials on the subject, yours was definitely the best. Good job, pal!
This is the best informative BMS video on TH-cam thank you very much.
Hi, many thanks for you video explaining the fitting of the BMS.You explain it very well when other videos skip bits out or dont fully explain it.Well done you and once again many thanks.
Glad you liked it!
Bhai solding se battery life kam ho jata hai😂 spot welding lagane ka😻
@@electro_king_official do this BMS has temperature sensing element (thermistor)
@@mohamedshafeelmohamedbilal6364 yes
@@bdgaming3485 yes u are correct
Very interesting and educative. I learned and ready to build For use and train others on how to learn
Very simple explanation. It Helped me to connect my 4s bms.
I like the detail explanation for beginner. Most other video showed with assumptions of an experienced dyi.
Oh, so you liked how he explained it did you? Well i guess if you read half of the comments, then your assumption would be half he did good and the other half say he didn’t do some things right! Gees, what you going to do now? He gives “likes”to both good and bad reviews about himself. Whats that tell you what he’s after?
Thanks a lot bro, I learned all about bms in this video from how it works and What the s value means
Bro it's tough to handle so much wires at a tym ..hw do you arange and remember tht all connections.. it's osm bro...keep it up..
my bro you helped me like never before thank you
many thanks for your VERY INFORMATIVE INSTRUCTIVE VIDEO , BRAVO !!! BRAVO !!! BRAVO !!!
Thank you... thank you... thank you...
Excellent lesson .Thank you master
your absolutely the best teacher i like your way 👌👌👌👌
the best video for this I seen on here thank u !!
Its always that random indian youtuber that helps us when we get lost😂😂
Good explanation
Excellent video my friend! Thank you.
very details,, thank you broth..
Well explained.... nd video is taken very efficiently.
Excellent demonstration.
God bless you my gee
Good video. However Please check updated best practices about soldering Lithium batteries, cable routing of the arrangement transiting hot zones, short circuits isolation papers for the ends of the batteries. Safety is the first one priority - Lithium batteries have high density of concentrated energy.
yes u are correct
He sounds Indian, they don’t follow safe practices. Have you ever seen their video’s on rebuilding lead batteries?
You called this a good video, then proceeded to explain what he screwed up on. He gave you a like so i don’t think you made your point!
sure!!
Great learning opportunity 👍
in the 6:05 you said that the negative is not connect with other positive but when you start soldering wiring at 6:45 the negative is connected with positive, i'm confused!!
exactly.. that also make me confused.. 🤔
@@donthadity Very confusing tutorial. Both sides are connected( that two lines). How funny
अपनी गलती ये अंग्रेज 21:01 पर वीडियो को कट कर के सुधारता है।
I was searching for this comment, glad that I am not the only one. XD
After Seeing the entire video, the battery series connections are actually ok but he placed the bms on the wrong end. Lol
Me too confused seeing the way negative/positive soldered.. It looks like +2 wrongly soldered to B- main.
Good job .. thanxxxx
Thanks for tutoriel, so charge or discharge on the bms it doesnt matter ? On the P terminal. I got a battery pack with ant bms
Good video best on TH-cam thank you.
Please can you let me know if my series and parallel connections are okay for my 24v 7s battery system or do a video on that
Great video thank you so much i finally understand how to wire a bms.but why are you soldering wires of bms in the middel of your pack?can you also solder it to the first cel?
Yes u can
Yes you can but it’s best to be in the middle of the parallel because range cause resistance, connecting the wire on the edge or cutting the wire can cause a slight offset to the balance of the charge but that only effects the longevity of the cells life a bit
Do you have to activate that bms? I'm getting the same one in about 4 days because the first one o got was defective. Is this one you just solider on and plug into the load?
no we don't have to activate
Good information
Grt bro
many thanks
Lakh video sai accha hai bhai
Big thanks
Nice job.
Hi, i would like to buy a little Daly bms for a project, but i don't know if i will use 6s or 7s. Do you know if the 7s Daly bms can work with 6s or less ? Thank you
Need to be exact on the series count. No more, no less.
Bro did you transfer bms? Watch 6:40 to 6:55 from separate negative to negative positive connection?,its kinda confusing
Right:
@@fifthavenue2240 the last negative is still unconnected
Do these cheap BMSs also limit the charging current? I got a smaller one of those for an old e scooter battery which I want to repurpose for an ebike.
Yes, for only small current but if it's big it will not and probably destroy the bms, so in charging we put some breaker or fuse
please help me i ordered 13s 48v bms but i have 91 cells so im making 13s7p will it work
Yes, go-ahead
Good job. Subbed
For 1000w hubmotor how much cells i have to use 60v 14s or 48v 14s pls tell me both
Check the working voltage of the motor, mostly 1000w motor works on 48v and if you are using lithium iron battery then 13s pack will be required
@@electro_king_official 48v 14s already installed in my bike i want to upgrade to 60v 14s, will it support to motor?
@@bashirahmed6111 check the datasheet of the motor if 60v is accepted or els contact the motor supplier and if you provide 60v motor and controller will burn
At time 6:05 you connected the BB- of BMS with the last -Negative of the bank and after almost 1 minute at time --7:07--, the BB- of the BMS is connected to the 1st -Negative of the bank, which is in series with the 2nd +Positive of the bank and then you left the last -Negative terminal unconnected. please reply just for the information
Exactly !
Something is wrong there ! It can not be the negative and 3rd wire conected toghether !
Is it required or statutory to use BMS for a 250watt, 36V front wheel gear motor and 36V 10A Lithium Ion Battery Pack Electric Bike? What do you suggest? Our FYP project is of a smart e-bike and we have to work on battery monitoring/improvements using some microcontroller. Please must reply, @Tauseef brother!
His connections are wrong
U are definitely catch it
Yes. If you have more than one cell in series you absolutely need a balancing circuit and a protection circuit that insures if things get way out of whack the charging or discharging current is shut down if any group reaches 4.20/2.50. It’s possible with an out of whack pack to charge up to the max charge voltage and have groups lower than the rest causing the highest group to be well over 4.20V. Same thing with discharging, one can be well below 2.50 while the rest are still at or above 2.50.
The max and min voltages are only safe if you have a balanced pack and the passive balancing BMS’s only have a balance current of 60mA or so. It’s entirely possible for a BMS to need a dozen cycles to rectify a way out of balance pack because the balancing typically only happens for a short time at the very end of the charge cycle and the faster you charge the less effective your balancer is.
Nice
You’re so nice
Can I use four 12 volt BMS to make a 48 volt battery pack?
no
Hi I've got the problem my daly bms thinks that ive got Lifepo4 but I've have li ion how to change the settings of bms?
You cannot change the setting bms is static u have to use a bms suitable for li. ion
Suuuuper videos
Thank you
Its only having C- and B- ...so can i use c- as charging and discharging?
Yes exactly
@@electro_king_official tq bro
***NEVER*** leave balancing wires connected to BMS while soldering. Disconnect white connector 1st. Next, solder. Next, check the voltage between each balancing wire. Last step is to connect balancing wires (white connector) to BMS.
Great point!
Hello... How can I buy this bms
very good
NiCE bAtTerrrrrriiiiiIIeeEEEeEEeEEEEeeE
Great video I have the same BMS but one thing I don't understand is how to wire the charging do I connect one wire to the red output and the other to BMS black output
It has same input and output put, u don't have to connect extra wire fro charge
@@electro_king_official Thanks for the prompt reply, The 2 wires coming from the charger socket in the battery case I connect to the 2 thick output wires going to the controller.
Bro from where we can learn the basics,like bms for simple less numbered battery packs,how to charge the li ion batteries,etc
Ok i will try to upload a video on that too
@@electro_king_official ❤️
Where do yu buy bms online bro..... Pls reply
Nope i have a dealer
60amps ke bms par apne 200apms ka load diya he to bms ko problem nahi hoga kya isse?
So if my battery is 60v 30a my bms has to be 60v 35a ?
Thank you very much. Please speak louder or get a better microphone. Why you chose to wire all cables on the 3rd positive cell of each series?
Can the amperes be increased to 36 amperes?
Yes
Hi tauseef can you please tell me whare did you get those laptop batteries
I would come to loyala hs when u came to teach there

Morning sir, I have battery lithium 104 pcs and the battery 20A is 2500mah. Total of 25ah. And i want buy 13s BMS and what amp can i buy? I what your help thanks
I have BMS stock the number is P13Q2S15D4M5/40-180-BO
So if u are make 48v battery pack with 104 cells then you have to connect 13 in series and 8 in parallel
And u have to buy bms of 40 amp
@@hiltoncrews4657 just tell me where exactly u will be using the battery pack
Like what is the pic current of the motor ?
I'm using a BMS with charge current 30A and discharge current of 45A for a battery pack of 48v and 30ah. Is it the best choice ?
And what impact will the change in discharge current effect in the working of ev ?
no problem u can use that bms
Bms will not allow more then 45amp of current to pass through it, if the motor pike current is more the 45 amp then buy 60amp BMS
What if you have 2 motors at 45Amp does that mean the bms needs to be treated at 90 plus Amps? Or 45?
Is Kay Liye Kon sa charger istimal ho ga 48v ka ya 24 12 Kon sa
54v ka
Bhai ap ki video me Samaj ai battery Kay se banani he charger per be AK video bana do
Please avoid cutting the length of the BMS cables as this changes the values of measurements.
I have heard its negligible on that short of distance but i don’t trust this guy to do anything correctly!
Sir 36v 15ah making lithium ion battery pack how many. S To set bms
10s = 3.7 x 10 = 37v
can you give a blue print of this
You are given connections are wrong please check

6:52 mins of the video you didn't connect the negative terminal of the battery but in 7:02 mins yuo already contacted it
How come?
Explain it!
Both sides are connected. How funny
Music in background is ruining focus on instructions
bro at 6:05 you said that the single terminal is negative and there no wire connected in series . then at 6:55 it has been connected in series.... whats the reason.....
Till 6:05 he was good.. At 6.55 his battery connections went wrong.. At 9:40 if you notice, he sorted the black and 2nd red together.. I hope he didn't run into problem when he actually started charging/discharging.. He has no knowledge of series and parallel. He talked two times that the last row is not in series.. Or may be he is nervous and talking bullshit infront of camera.. Please don't follow his video.. It may lead to mishap..
@@clicktodhruv exactly bro.... he is misleading everyone

At 6:46 the main negative is not connected in series, however at 6:56 it's connected. what's going on there? why didn't you say anything about it?
please watch 21:01
How can 14S be 48V? It is 51.8V. So why does BMS say 14S 48V?
No you cannot use 14s to build 48v or because the full charge voltage of 14s is 58.8v (4.2*14=58.8) it is going to overcharge your cells
P= Pattern C = Charger B = Battery
6.40 8.36 batteries not the same incruding your wiring
Why is your balance wire’s connected to bms while your soldering to battery! Every person on TH-cam states to solder/weld wires, check with muti-meter, then plug into bms! Also if you want 60 amps output, the bms will normally limited you to 30 amps going into the battery to charge. You bypassed that protection by using P- as your charge wire! So if you charge too fast, haven’t you shortened the life of battery? Why put a bms on it!
I had already checked the output of all the cells before soldering and I am providing 5amp of current to charge the battery which is around 20% of the capacity of the battery pack, so it is safe and even after 3 years of built still iam getting stable output range
How is he bypassing? The bms doesn't even have a c-. His negative terminal is at p-.
Bms cancat rong from nagtip wair
Background sound so noisy
Technically your video is right, but you didn't mention any safety measures at all, working with batteries is a huge danger. Your solder joint are very low quality, I am sorry
yes you are correct
