I've watched a lot of these videos but this was the one I found to be the most clear by far, good stuff.

[@joelcortes6040]

I watched 1000 videos and couldn't figure it out 🤣 Thanks for sharing your video you have no idea how helpful this was 👉

[@William_ar98]

THANK YOU! Very clear explanation and no confusing parts, just what i was looking for.

[@kivenwalters7507]

I see I'm not the only one who finally learned how to do this from watching his video.

[@jussgotlifted3822]

Thanks brah. I'm rebuilding a battery pack and I was confused about some things but this video cleared it all up.

[@kivenwalters7507]

Bro you explained this better than anyone else. Thank you

thank you just found out your channel, brilliant info, much appreciated!

beautifully explained I get it now ( with all they red wires ) thank you for sharing

[@bitsnbobs1969]

well this makes sense and easy way doing it i seen many videos on this bms yours was easy to under stand

❤VERY GOOD , IS ONE OF THE UNDERSTNDABLE TUTORIALS 🤜🤛 THX

[@christopherowens2635]

Is there a pattern when hooking up the bms wires? I first hooked up all the P-,P+,C-,C+,B-,B+, from the bms to the battery, then when I started finishing the balance wires, I noticed little smoke was coming out of the bms. Am I supposed to wired the balance wires first?

[@startcherif]

Good job. Very nice video. Thanks for your info

[@milvolts1]

Hello, I am hoping you could help me with this question. I made 3-24p 18650 battery packs, wired them in series to get 12v @ 60 ahs and added a 100amp BMS. Can I make a pack just like the one I mentions to acquire 120ahs? Thank you for your feed back. Have a nice day.

[@adrianstealth340]

Thanks for vid , does it not matter for each battery neg - or positive + for the BMS ????

[@MrMazizo121]

Thanks for sharing your knowledge

[@demolitionwilliams7419]

Bro you did such a great job with this video. Well done 👍

[@jamesbenedict6991]

The bms was helpful. I build my own but was looking to see how others do it. I'm curious of how efficient they are after stepping down the power and balancing the cells. 36 volt at 40 amp would be about 400 amp at 3.6. If the power is split by resistors then there would be about 10 amp per cell. I bet you are losing about 20 to 40 percent power but it would be nice to see. You should see how much power per cell and how much power going in to see. I use large ah 3.2 volt cells with a much higher current charge. I have a lot more bms equipment but a lot more efficient design. I use no resistors and don't step the voltage down

[@utoobfan7203]

hi, what about the connection to the ESC and the charging port on the battery ?

[@fwefhwe4232]

simple english, clear explain. thanks

[@salvadormontanez6278]

Just trying to learn..here the max discharge of those batteries based on LG documentation is 20a...2.7 Max. Discharge Current For continuous discharge 20000mA..2.6.2 Fast DischargeConstant current 10000mA , 20000mA...I'm confused how much discharge the motors do? Can you help me with that..why 20a or 30a max discharge work satisfy both motors? would 30am will be better? for that same setup?

[@herbsabeast1]

I was curious to know if this could power an electric skateboard?

[@davidjames2235]

Thank you big help.. So probably a silly question if I wish to make a 12s all I need to do is and an extra pair on the end.??? Cheers David

[@JustVlads]

Yep, adding two more would make a 12s. Cheers

2 thumbs and 2 toes up. Just what I was looking for. I'm a NuBe. And this video cleared things up a bit. Would this build you talked about be the same for a 36 battery 12v pack. And would that pack i just mentioned be called 3/P or 3/S.

[@MannyM0E7O7]

Was there a assembly video ?

[@zondepa5537]

Thank you very much! U helped me alot! Do you think, the battery box with the springs is better and safer?

[@aznative_]

Everything he said was great up until the point he tried to explain the schematic for how to wire the 10 wires. His explanation was actually backwards and would absolutely fry your BMS if you did it the way he described.

[@interestingspagetti]

I did think you were guna build. But nice vid. Liked

[@tonysfun]

Where is the second video? Thanks for sharing.

[@cyprianchima5917]

Cleared good job bro

[@taylorsprojects345]

Just trying to help. If anyone follows your bms wiring they are going to fry it and/or there cells. After the black ground wire you start with the red one next to it in that order. Just look at the diagram you showed. You are trying to teach everyone starting with the wrong positive and going backwards. Don’t want to step on your toes in what your doing. Just trying to help. I’m probably going to make a similar video in the upcoming future. Hope my 2 cents helps

[@jameshartman6044]

Thank You. I was going to say the same thing until I read your comment.

[@SavageKid23]

Ok i did what vlad did and my 10s bms heated up.

[@SavageKid23]

Can i still use the bms?

[@KeigoMoriyama]

Brian Taylor how to do then? Please help

[@aznative_]

@@KeigoMoriyama in the video he essentially described it exactly backwards. You start with the black wire and you connect that to your negative terminal. Then the wire right next to it goes to your first series connection. Then the wire next to that goes to the next series connections so on and so forth until the last wire which will be a red wire is on the positive terminal.

[@bubblebut9268]

With what kind of wire did you connect the cell holders?? Or dit you solder nikkle strips to them?? Video helpt me a lot!!!!

[@JustVlads]

I just used a 16 gauge lamp wire. As long as the wire is copper it should be fine. Thanks

[@jamest.5001]

lithium batteries don't come fully charged. and storing fully charged long term can shorten the life. I font know if I'd trust that much current through those holders.

[@karlstern3436]

Hi! great video! I have a semi-related question.. I have a few (3) batteries, each with a built in bms constraining output to 50 amps. If I wire them in parallel and try drawing 120 amps, will it compromise the batteries?

[@joaquinninoortega156]

Theres no reason to use bms for discharge unless you want to limit your battery? In skateboard if you do that you could get crashed, esk8 sudden stop, careful.

[@paras1721]

where is installation part ???????????????

[@Drxxx]

How many volt for charger you will need for bms 10s

[@einmax879]

So i got a 10S6P Pack, soddering finished, now i somehow need to Install a BMS, but there are no 10S6P systems Out there (If there are, pls Link) should i Just use 6 of These?

[@aznative_]

Bms's do not monitor single cells unless it's a 1p battery. Bms's monitor groups of cells, each individual parallel group. The same BMS you would use for a 10s 1p you would use for a 10s 6p.

[@dissonant__]

Does it work for 10s2p?

[@mashallah8619]

Can I spot weld the batteries instead of soldering the holders together?

[@isaaclyonsf1]

Yes

[@longle7603]

Two questions 1.) Can you charge and discharge from the same discharge port? 2.) If you use the charge port can you discharge at the same time?

[@bereal1251]

Do the mah stays the same or 3000mah x 10? Awesome video by the way very easy to follow sub:)

[@JustVlads]

If you connect in series the mah stays the same but you multiply the voltage. If you connect in parallel than voltage stays the same and the mah multiplies. Hope this makes sense

[@unaillamas4360]

@@JustVlads it actually makes sense, what i'm not really sure about is the battery life that skateboard will have, cause with that cell configuration your capacitance is 3000mAh, which is not much.

[@atiquemian7825]

Could you do installation please

[@JustVlads]

CHeck out this video: kzbin.info/www/bejne/bqfIkGpnetZ8obM

[@nicholaslabrecque]

to anybody that is watching he points out the count in reverse you want to start from negative then go up to 10. if you where to check the voltages counting up they would increment from 3.7 up to 36 volts the way he counted was de-increment this is wrong and you will possibly fry ur BMS

[@aznative_]

And just in case people were so impressed with the video not to listen to this comment Nicholas is absolutely correct. Wire it the way the video tells you to and expect to fry your BMS at the very least. You always connect the negative to your negative terminal then the positive or next wire to the negative goes to the first series connection then the next wire goes to the next series connection and so on and so forth. The last wire should end up at the positive terminal. If it does not you did something wrong. So basically the video tells you to do it backwards. This video should be flagged for removal.

[@thisphone2538]

Thanks guys.. thought it was wrong.. the red wire next to the black goes on the positive on the cell on the posititive side of the pack negative. Man this is hard to verbalise The red wire next to the black goes on the positive of the cell to the far right of the pack then you can work your way across right to left.. was that better?

[@terrythurston8572]

Brill. Thanks

[@bereal1251]

What's the capacity I set my charger is it still 3000mah?

[@JustVlads]

If your pack is 10 cells the 36v the capacity is 30,000mah. If you are charging an individual cell 3.6v the capacity is 3000mah. Hope this answers your question.

[@bereal1251]

@@JustVlads I made a 6cell pack in series 3.6 a cell at 3000 mah per cell so do I times the mah by 6?

[@JustVlads]

Thats correct your capacity multiplies per each cell. So if you have 6 3.6v cells giving you a total of 18,000mah capacity. This is how your pack will be specified - 21.6v at 3000mah = to 64.8 Watt Hours. Its the same as say you have 6 3.6v cells in parallel giving you 3.6v at 18,000mah = 64.8 Watt hours. So its more easier to understand total capacity with watt hours than with mah. Hope all this is making sense.

[@2dthoughts]

Awesome Thanks for the vid

[@id15807936]

Didn't he made a battery of 18650 batteries?

[@aznative_]

You did a good job putting the video together but unfortunately the information is absolutely incorrect. The way you described how to wire the BMS for the individual monitoring of groups of cells was backwards. The easiest way to understand how to wire a BMS is to start with the black wire. The black wire gets tired right into the negative terminal that you have created for your battery. Then the red wire right next to it goes to the first series connection and you keep going on and on like that. What you did was set everyone up to fry their BMS. Do the right thing and recreate it with the correct information. You're literally liable for any damage that someone does based on your video. I didn't see a disclaimer. And don't think in terms of ruining a BMS. Think in terms of burning someone's house down and killing people. Not cool to put together a video showing people how to do something inherently dangerous when you're not quite sure yourself what you're doing.
