I got to give this a huge thumbs down. First of all, you're using a 25A discharge BMS with 3.2A discharge batteries. That's a very bad idea. That means you have no discharge protection and the batteries will overheat if there is a great draw on it. DO NOT use this in power tools. You might know how to put them together, but you have no clue what you're putting together. Secondly, those solder joints are made to fail. They are an abomination and you should not be building battery packs with such poor joints. Lastly, if you're going to use old/used batteries, do some current testing on them. By putting this on UA-cam, you're teaching people. You need to teach them how to match cells. Teach them to be safe first and foremost. This needs to be removed because it is an absolute hazard in every sense.
Is it then simply a case of using high discharge batteries in order to avoid the overheating? When selecting the BMS (in my case it would be for a power tool), which of all the listed battery parameters would I be looking at to know that value? I'm presuming "Over discharge protective current" - is that correct? And finally, when checking battery discharge against BMS discharge rate, are we talking discharge per 3.7v cell, or do you multiply the number of cells in series by the discharge rate per cell and compare that to the discharge rate of the BMS? Many questions - and even more thanks to you if you answer them!
Hello! I'm planning to replace My circuit from 20v battery. Anda I think this migth work. What de You think? Joe pong does ir tales You to fully chahr that battery?
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.
In discharge for a drill application what happens to batteries if a max current limit is reached but over temperature is not reached (short drill stall conditions)? I assume that will be OK if one waits few minutes to cool batteries down. Any practical experience comments out there?
The board has discharge protection for as high as 25A. This should work for most cordless drills. The batteries however are only 3.2A discharge batteries. The batteries should not be used for any power tools. Use batteries that at least have the same discharge rate or more than the BMS. If your battery is lower than the BMS, the drill will draw great deal of amperage and the batteries will heat up because they will be forced to provide more amperage then they're designed for. The BMS can not engage discharge current protection before damage to the battery is done. You don't want hot batteries, it can be hazardous.
@Herus thank You. If we use a pwm setup, can i connect the battery pack to the D.C. out of the charge controller? For charging it.. like we would charge any power bank at any wall socket..!
I have 5x3.7v 18650 batteries which is connecting to LM2596 Dc to Dc converter for 12v output. Is it worthy ? Also is there any requirement of BMS circuit?

Bro instead of lithium battery Can we use five 4 v yellow colour lead acid battery Which u used to make 5 v rechargeable emergency led Plz make video on this bro

Does the output cut out when one of the cells drops below the discharge threshold?
How do you know when it fully charged? Any BMS board with the light indicator you suggested. Thank you
not clean work. for safety and battery life , spot welding with nickel blade is better.

one question do this board balance charge cells or not?
2:02 yes
Balance charge yas or no ? Real

21 вольт нужно подавать, и лучше специальной зарядкой с индикатором.
Is there a range specified for this board to initiate charging? Is it something like 21 +/- 1V or tighter tolerances than that?
@@dubmob151 Sorry, I couldn't use these circuits. I think there is a production problem.

Can we charge it with laptop charger?
Is this board good for cordless drill? Where to buy it?

Hello.. can we use a solar panel to charge this battery setup. If so..what should be the voltage of the panel. Thanks in advance.
Yes, you can.
but maintain the charging voltage level

👏👏👏
Can this be used with a 20v laptop charger?
Same question
Cuál es el amperaje de carga que se debe usar?? Estará bien con 3 amperes o debe ser menos
Balance charge available yas or no
Hi sir.ask ko lang sana sir pwede ko bang ipagsama Ang 3.6v at 3.7v sa 3s 4p?sana masagot mo Ako sir,,salamat
can you please post BMS's schematics diagram ?
internal circuit diagram or pcb layout etc ?
ok, I'll try
Can i charge this bms 5s with a 25v power supply or need 21v ?
you can use 21v DC, don't use above 21v

Nice
Do u have any way to contact ?
THIS UISCRAPm,i it cuts at 5 amp not 30 as stated, it couldn t drive my angle grinder, VEEEEERY SLOWELY its CRAP for tools
Poor performance. Never heat up or solder a lion by.
Good
An indian hand a monster solder iron from Nazi's
Bro instead of lithium battery
Can we use five
4 v yellow colour lead acid battery
Which u used to make 5 v rechargeable emergency led
Plz make video on this bro
