amigo es bms no tienes que quitarle unas resistencias para utilizarlas en las diferentes combinaciones???

[maatiraouki]

C’est excellent merci beaucoup pour l’exercice

So using 5S, if you wanted, say, 19.5v to drive LED strobes, I guess you could wire in a separate output leads to a LM2596 Buck converter to limit the 5s final voltage to 19.5v, correct?

Hello. I am using the same bms module. There are 2 of them, 1 is used and 1 is never used. I made the connections as in your video, but the voltage on the output pins seems exactly half of what it should be. For example, the voltage of the batteries connected in series is measured as 20.8 volts, but at the output pins of the bms circuit it is measured as 10.4 volts. I apply a voltage of around 24 for charging, but the bms circuit does not perform the charging process. The same problem applies to the old and the new.

[samueloneill]

So where can I connect the 12.6V output to a device? Do I use the same output as the load and charger?

[Vagubando]

Do I need to connect (weld, solder) batteries to the BMS board in sequence (from plus to minus or vice versa) how is it in the laptop battery so that the board does not go into protection?

[wiled]

Hello friend, I have the same bms board, but I bought it for 5S, and the 5s does not have the three resistors next to the positive with a value of 0.
Therefore, it could not be configured for 3s or 4s. I have simply made a bridge for it and now I can configure it. This is done by the manufacturer to be able to put three different prices according to the cells.
If you make a video explaining it it would be perfect, if you want to do the test to remove the three resistors you will see how it does not work.
All of this has taken me a while to figure out.

Thanks and sorry for the translation.

Great tutorial on how to do everything wrong!

[sammy]

Hi Power Gen, great video, but now they have more advance BMS board in the market with 10 MOS, is your 4cell suitable to use with the 40A board, your advice please .. tks

[divikumar]

Hi there nice video, I wanna build a battery pack, should I go with 1S10P configuration with boost converter or 3S4P configuration for 12V application?.

[ScienceFunInnovations]

Looking forward to trying this on future projects.

[solsticex]

Please, can you make 36v Batterie from 4× 9v Batterie??
I want this for my escooter
Thanks

[y-linkengineeringgoodlucke]

Please what is the liquid you are applying on top of the battery before before soldering ?
Because the problem we have is sometime soldering on top of the battery is somehow difficult

[arupamdutta]

Hi... if I use BMS 3S 10A then let me advise which adaptor would be the best for charging? Your circuit is really helpful.

Plz add Voiceover For Better Understand

How to charges this battery type of 12vot 21volt and 14vot and which adaptor is used for this

[darshitmathur]

Sir mere pas 12v ka smps adapter hai jo around 15v ka output deta hai..mai usme kya katu ki mujhe 12.6v ka output mil jae...thank you

[VARocketry]

Do I understand that this provides 3.7 x5= 18.5v max, or is it 4.2x 5= 21v? I read 18650 max voltage is 4.2v.

[solsticex]

Can i charge 5 × 9v Batterie with this bms Board??

[shmuelnaarai]

Can this protection board be used for cordless tools?
