Hey people, If you want to skip the part where I rewrap the cells you can just go to 4:00 to see the actual pack being built. Now that I think about it I should've cut the first part out since it's not important...
Thank you so much for the beautiful video! After witnessing your video I could understand that the battery pack can be charged using walwart having atleast 50 percent amperage of the battery pack and also the charging can be done BMS added to the pack.
I was made 18650 lithium battery 3.7v 2200mah with three batteries ups I put charger 12v with 1A but it's battery drain so fast like 10 mints work only ??
It depends on the load. If you're using the battery pack for something power hungry, then yes, it will drain fast. If you're talking about drain while there's no load connected, it might be a bad BMS. So look into the load first.
There will be high heat on some parts of the board usually, you can try and feel it with your fingers or just wipe a bit of alchool on the board and see if it dries somwhere much quicker than other parts of the board. If you have a thermal camera, it would be easier but it's an expensive tool if you don't already have it.
Thank you so much for this video. Dis actually helped me alot. I knew how to do this but you explained everything very well. Thanks so much. Gonna build BluetoothSpeakers with those Packs! Bigups.
@@FrederickTL I know that connections ie B-, B1, B2, B3 but I wonder how I will connect power output terminals of this pack. Which terminal is P+, which terminal is P- ?
Oh yeah sorry, you have to connect it to the B3, since you have 12v there. So positive is B3 and negative B-. If you don't have space to solder the wire on top of the board you can use the pad on the back.
i have power coming from mppt controller, 12 volts 8 amp. Should i use 10 amp BMS board on 3s3p 18650 pack or the current is too high? I probably should connect only 3s6p pack with 16amps ...right?
Thanks for this video It was very helpful for me. I made two packages of 18650 like this to have more play time, so I combined the two packages together in parallel, my question is: which board can I use and what voltage should I apply to recharge them?
If you connected them in 3s you can use a 12v power supply to charge the packs. You can connect the outputs from each pack together and just charge them from that connection... You don't need another board.
@@FrederickTL Sorry for my English ... I created two packages of 18650 identical to yours but without any control card, I then joined the two packages by welding together the two positive poles (from the same point where the red tester is at 6:24 in the video) and the two negatives. Now I have 12 volts with more play time and I don't have any control card yet, my question is: which control card should I buy and how much current should I load to charge the final package?
I don't recommend the chip i used in the video since its failure is very common. You should take the "HX-JH-001". It's much more reliable. As for the current i think 2A should be safe and quick enough to charge it.
I can't put links because some of them won't last for long... So i put the name of every component so that you can search it on your local online store.
hi thanks for the quick answer but my question is about m'I able to charge and use the battery attached the same time for example when you charge your phone and use attached the same time ( laptop charging situation ) thanks for help and sorry for the bad grammer:)
Yes, you can, but there are two things to note: 1) you will need 2 connectors instead of one 2) the power supply should have an high enough Ampere rating. Because if it's too low, the power supply won't be able to charge the pack quickly enough. This is not a problem if the pack is not in use while charging.
Let's put it this way. Let's say that you've got a 12V 2A power supply and an electronic device that draws 1.4A constantly. If you connect the device to the battery and the battery is being charged with the power supply, the power supply will feed 1.4A directly to the device and the remaining 0.6A will go to the battery (if it's not fully charged). Let's make the same example but this time with a 12V 1A power supply. The power supply will feed 1A to the device and since the device needs more power, it will draw the remaining 0.4A from the battery. So basically in this case the power supply it's not "powerful" enough to charge the battery and give power to the device. Sorry for the long answer :)
The capacity depends on your cells. Let's say that you have 6 cells and each one of them has a capacity of 2000mA. If you make it into a 6S pack, you'll have a 22.2V 2000mA pack. In this case you'll have 44.4Wh which would power your 200W speaker system for about 10 minutes. So to have more playtime you'll have to make multiple packs and connect them in parallel.
Wow nice tutorial I need to build such a battery for my rc boat The actual battery power in 12 v 5200mah What about if I add 2 more cells ? Is possible to configurate it such way not to burn the motor ?
It depends on the voltage of the motor. You need to check the maximum voltage on the motor's datasheet. Also if you're planning to put the cells in parallel there shouldn't be any problem. You need to be careful when you put the cells in series.
Thank you for liking my comment. The first song reminded me of Daughter - Medicine (Sound Remedy Remix). It's not NCS, but I think you might like it. th-cam.com/video/cSPfeTwl8Kw/w-d-xo.html
You have a problem here. Your BMS is not properly balancing each cell. At best it is balancing every 2 cells. To do this properly you need to have 2 BMS units so each cell has its own charging/metering unit.
Yes, I know that. But I wanted to keep the circuit simple, that's why I opted for this solution. Also if the cells have never been used or always been used together that's not a huge problem.
@@FrederickTL Thank you for your reply. I can see your point. However as I spent several years as a field tester for several manufacturers of Lipo and liion imbalances between cells, even from new can and do occur. I know that newer batteries are far better than back in 1998 through 2011 when I did this work. But I would still have independent balancing flow to each cell. If you don't you may as well just treat the pack as one and just allow natural balancing, providing you are using a proper lithium charger.
It hasn't got a discharge rate great enough to start a bike... Only 10A on li-ion.... You could do it by making the same pack but with li-po batteries. They have a better discharge rate, and they are commonly used for car starters.
I recently bought some nickel strips. About the spot welder, i don't make battery packs on a daily basis or in mass production so it would be just wasted money.
Well, technically this isn't a tutorial, it's a video documenting what i'm doing, which is: Making a 12v battery pack. A lot of people tought this was a tutorial and since there was the wrapping of the cell and also the fact that I didn't give much in-depth info, they gave a thumbs down. Thanks for the feedback though, appreciate it ;)

Hahahahah
I lit my Eneloop AA batteries on fire doing something similar. My first or second upload to my channel like 8-10 years ago.
I like how you rewrap these 18650 cells
hi , can you post a diagram on how you soldered the cells together?
I'd suggest going with battery packs where the battery . It'll make life easier when one goes bad.

@@FrederickTL load its only 9v and 600mAh
Then check the BMS or short circuits between the batteries
@@FrederickTL how can I check short circuit ?

i just wasnt sure about the BMS. Can i use any 12 V Power Supply? like one with 20 A or 5 A?
or shud it be one with Output 500ma?
You can use those power supplies but I think the BMS is limited to charge at 2A so it will only charge at that current.
@@FrederickTL THanks! And can I leave the Amp connected to the BMS While i charge? Or shud i disconnect while i charge?
You can have it connected while charging.
Could we use HX-JH-001 instead of this circuit card, then how will the wiring, P- and P+ connections be?
With the HX-JH-001 you have to connect the positives of the batteries in series on the B1,B2 and B3 connection pad.
@@FrederickTL I know that connections ie B-, B1, B2, B3 but I wonder how I will connect power output terminals of this pack. Which terminal is P+, which terminal is P- ?
Oh yeah sorry, you have to connect it to the B3, since you have 12v there. So positive is B3 and negative B-. If you don't have space to solder the wire on top of the board you can use the pad on the back.

Does the BMS module cut off the charging input when all the batteries are full?
Yes, that's one of the main purposes of the BMS
Putting a link on the description, for the material you used would be nice
I can't put links because some of them won't last for long... So i put the name of every component so that you can search it on your local online store.
Hello.Please tell me, if i made this with 9 batteries (3+3+3 same config.) do i get 12v?thanks
Sorry for the late reply, youtube flagged your comment as spam. But yes, you can use that configuration to get 12v and more capacity.
@@FrederickTL thanks!
hi whit this set up can i charge then connect them to the divace at the same time and youse just like laptop batteries in a laptop it self?
Yes, you can use the same connector on the battery for the output and the input.

How much amps battery pack is this
Capcity: 4300mAh
Peak power: 2A
Can i use this pack in an portable speaker
If it needs 12V, then yes.
How much hour it will work
It depends on the power draw of the speakers and the amplifier
does capacity be double with 6 cell.can batery last longer compare with 3 cell
Yes
does amps goes up for12v batery if you conect 6 cell or even more cell
No, the amps are managed by the bms
Showing more detail slower would be a great help
I also think so and also I would like to see circuit diagrams both with the batteries and BMS board connections .
Just slow down the playback, it is really simple.
How do I get 24v from 3.7v 18650 using series
You have to put 6 cells in series (6S) so that you get 22.2V at nominal voltage and a maximum of 25.2V when the pack is fully charged.
@@FrederickTL but the capacity will be very less I assume?
@@FrederickTL I am planning to build a 200wrms Bluetooth system and trying to power it with 18650 the amp works best on 24v
@@FrederickTL so the wattage will be around 200w

Whats the pros and cons for having 6 batteries instead of 9?
Well, i think the only pros are the reduced weight and the smaller footprint... The only con that i can think of is obviously less capacity.
@@FrederickTL makes sense thanks!
Can you mention the net weight of the battery pack?
280 grams
@@FrederickTL thank you

If the battery does not break
Then what?
Oh ok, then it's not. This is for small electronics, you need a lot more cells and a specific bms for bike battery packs.
can the battery be charged at 12v 1A and is it safe to charge it like that with BMS ?
Yes, it's safe
@@FrederickTL I would like to make a boombox so 12v should be needed I added a switch for switching to charging to amplifier mode a dpdt switch
What is charging time 1h
With the 500mA power supply that i used in this video it takes about 9-10 hours to charge. With the 2A one, about 3 hours.
how much time this package is loaded on this power supply ?
On the 500mAh one it takes about 10 hours to fully charge from flat. A more powerful power supply is recommended.
