Two suggestions, if you like. Wrapping krypton tape stops the air flow which plays very significant role when the cells heat up. Raise a L end for soldiering wires so as to avoid heat going into the cells. Perforated fiber sheets on 4 sides may be put for mechanical denting.
I want to do this with 38120S cells to build a 12-14 volt 80 (ish) AH battery pack, can you recommend a good source for information on this? I do not understand how you came up with the grid pattern for the buss bar.
Hi brother, i made a 4s lithium ion battery with a 30 amp bms. After completing the wiring the bms out put voltage is below 12 v. At the battery end its 15 to 16 v. I did nt connected to charger yet, only connected a battery level indicator,.. When i first conneected the charge indicator it showed the charge which is full, after some time its not shwing anything. Then i checked the out put voltage found below 12 v. Is the bms damaged?
Great job friend, but I'd like to know how wiring the same BMS board as a 4S2P pack, but, seeing where each wire goes where and voltage at each wire soldering, all videos I've seen they cut out and go to end showing the finished job. Thank you.
Very late, but: the wires go to the same place, at each split between series cells. You are still 4S, so you still have the same number of wires going to the pack. The extra parallel packs don't change the wiring, the parallel packs are joined at each series split.
@@MarkPentler A bit late 😁. But thank you so much for replaying. This time I've just finished a 5s4p project and, of course, learned something about assembling batteries packs. Thank you, you're always welcome
@@SteveWillsonKujur I bought 3s 60a bms but it has different charging and discharging points know I don't know if I'll be able to see if it's full charge In my mppt solar charge controller
Nice video mate... the trouble is with almost every one of these videos that you clever fellas make.... you don’t explain our show for long enough to see what the battery spot welding configuration is as in where to connect the strips to what batteries pos and neg terminals. When you’re learning like I am that level of instruction would be great 👍
@@rogergreen6953 the 4s4p configuration means.. there are 4 sets which is created with 4 individual cells. Each group of 4 cells creates 1 set. On each set there is one positive and a negative. On the BMS you have B+ which goes to the positive on the end of the pack. Same with the B- which goes to the negative at the end of the pack. Positive and Negative are located opposite of each other. On the BMS you will find B+ and B-. Those are connected to each side as explained above. You will also find P+ and P- those are used to wire the Positive and Negative wires used to power whatever device. You can use any battery connector to connect to whatever you desire. As for the BMS balance leads connection which are labeled B1, B2, B3 a wire goes from those pads to each positive cell in the 4 groups. You wont find a B4 because the 4th positive is considered B+. I hope this helps to fill in the gaps. Learning is key and not everything is given in a video. You have to do your homework..
@@acdlogistics586 Yes. Not sure what you mean by "doing the same thing." Each one of those leads are combined into the balance plug. 4 positives and 1 negatives. 5 wires.

You totally could hand model. Nice complexion and skin tone. Im jealous.
the voltage of a fully charged assembly is 16.8 volts?how many amperes of bms?
Up

Yes it's a faulty BMS

Great video & helped a lot. The other half, who was listening from the other room & thought i was watching naughty movies with the music. lol
Great job, for whom knows a little is great help for a 4s4p configuration.
I need a plan to make this Pack with balancercabel.
Can I use a 16v transformer charger for it?
hi bro
how make 6s6p battery pack in this model...?
what is the white connector on the BMS for?
Can you start a motorcycle or a car are the amps enough?
This battery can't
how many mah does it have and what voltage i need to use to charge it?
And, where is thermistor placed?
Kitne ampere se battery ko charge Karen sir pls ans
Awesome work, dude. Really well done! 😊
Thanks man
@@SteveWillsonKujur Looking forward to the project where you're going to use the pack! 😃
Stay tuned
@@SteveWillsonKujur Always! 😊
Can you change and discharge in the same time
Yes
@@SteveWillsonKujur I bought 3s 60a bms but it has different charging and discharging points know I don't know if I'll be able to see if it's full charge In my mppt solar charge controller
How do I charge this 4s 4p battery pack, I want to charge it with 16.8CV and ?????CC. So how many amp should I use to charge this pack. Pls help
4.5 amp recommended
@@SteveWillsonKujur thank you
Hi
This config is new to me
I didn’t know we can have 4S4P in this way too.
Can you share some kind of diagram to explain this configuration
Bro can i connect 4s lithium battery level indicator...
Very nicely done. 👍👍👍👍👍
hi nice video can you circuit diagram of series and parallel connection between cells.
What is the song used in your video exit? and used in this intro?

yes i totally agree if some was too explain and show where the bms wires are attached and the orientation of the bus bar etc we all have too learn

@@FlyHighforfun So the B1 B2 B3 is doing the same thing as the small white connector with 5 wires?
@@acdlogistics586 Yes. Not sure what you mean by "doing the same thing." Each one of those leads are combined into the balance plug. 4 positives and 1 negatives. 5 wires.
@@FlyHighforfun So it doesn't matter if you connect it through the leads or B-tabs?
Здравствуйте а как собрать 4s5p?
Sering juga tidak ada yg dikawal tapi tetap nyala lampu strobo dan sirine yg sangat mengganggu
Try to make powerful 12~14v lipo battery pack for charging stuffs for survival or outing ....
Okay I'll make it
Very nice 😊
Excellent
Diagram pls
Informative H
what... did nothing....

Dont like the video. You shortcut.
