Aah Exactly what I was looking for 🌿

[@I_Am_SoSo]

where does the white wire connect to?

[@doitgirl]

the white wire does not need to be connected as it is a date wire

[@benedictcaluza1997]

Can i direct with with a cellphone charger instead of using battery?

[@doitgirl]

Yes and no . the voltage of a usb charger and 5v for that and those converter convert it to 3.7 as security. 5v may not burn the column immediately since there is little discrepancy. but it can certainly cause problems later. solution if you want to use with direct usb or buy the spare part if you find it, or look for a card that converts 5v to 3.7 and can connect through any usb input www.aliexpress.com/item/32817933017.html?spm=a2g0o.productlist.0.0.780c17cbrp8z4p&algo_pvid=6cb29b73-8f91-4f82-93ee-b342d2ac70fc&algo_expid=6cb29b73-8f91-4f82-93ee-b342d2ac70fc-1&btsid=0b0a556116077079564095360e340c&ws_ab_test= searchweb0_0, searchweb201602_, searchweb201603_ first solder the column cables to the output of the board then use a cut cable with usb input place the red on + and the black on - on the board input. and so you can use it directly through an alternative USB input, making it more affordable. I can later make a video with this solution. :)

[@doitgirl]

it is also possible to connect the input directly to the gbl board where it converts to 3.7v to power the speaker. like this originally. soldering the cables the 4 slots or at least 2 to + / - the rest and for data and updates. since this was my first video and it was not very good I will soon release a more preceptible update of this video with 3 ways to recover without buying original parts.

@@doitgirl bro, do a video about it i really want to use my speaker as a corded one because the life of the battery isn't enough

[@doitgirl]

@@whos_noner7189 I'm sorry I'm having trouble finding a jbl economic trash to demonstrate, but I'm trying to make a video exemplified as. I will try as soon as possible. but if you use a good 18650 2000mah battery it lasts 4 hours or more

[@themattprincebrotv2369]

2 wire for battery and 2 wire for charging ?

[@skylark1848]

Can you show me how tp connect it to a 5v charger? ?

[@harunsivasl4983]

i did same but its not working, battery heats up. it seems like there is a shortcut but i test it with multimeter and there is no shortcut. Any idea? by the way i removed charger pcb by cutting all cables. Thanks

[@doitgirl]

do not use the charging input, the battery must be connected to the battery input as it has a control circuit. to adapt to the loading input you need to keep the control board.

[@rosekreuze]

mine atleast i think uses a 2s battery configuration. its a charge 3 and maybe yours too, that means it uses 8.4v

[@doitgirl]

@@rosekreuze I am sorry that I went wrong, but it is logical and I warn you again be careful with the polarizations be careful we are only using a 3.7 v battery and we are using the battery input port.

[@rosekreuze]

@@doitgirl i just replaced my charge 3 battery, well im surprise it is infact a 5v configuration, two in parallel. I thought the tiny board was a bms but just a simple board with a fuse. I replaced it with just a normal 1700 mah 18650 and cant keep up an hour under high volume and generates heat. Maybe thats why the old batteries were in a parallel to be able to handle such high current discharge while using. And we cant obviously fit two 18650's right. Or did someone tried using a high drain 18650?

[@doitgirl]

hello Harun, are you using a 3.7v type 18650 battery? when we use the battery input the voltage to use and 3.7v don't use the charging port i need to make a video on how to do this correctly. yes if you are heating it is likely that it is shorted out. checked the polarity? try to change the battery and see if the same happens but be careful battery heating is dangerous. I can say that it could also be that the problem is really something in the circuit and this is the general problem and not the battery itself. Try to check and tell me something.

[@arminarjona]

Where the black wire came from? ( the other one )... 3:30

[@kolemlg]

I have question. I have jbl charge 3 but battery is dead. I find 18650 battery with same mah as original one. Can it run with BMS from old battery and does make some changes like fast draining or something. Thanks.

[@doitgirl]

yes, but just if bms is good

[@kolemlg]

@@doitgirl well, when i play some music after some minutes it start cracking because battery is drained. I put to charge it but it shows like it's fully charged. Probably bms is dead, like you said. Thanks for advice.

[@doitgirl]

@@kolemlg hello again, the crackling sound may have another cause, for example when you closed the speaker, it was vibrating close to the structure, but this happens more in loud sound. Is the battery you bought good enough? third if you don't charge directly you can use the battery without bms "the external one" and charge the cell externally. Connect to the poles where the battery is located, pay attention to the positive and negative.

[@kolemlg]

@@doitgirl i think battery is low, because i using from old laptop one cell, and i think that's the problem, i charged battery directly from 5v supply and works perfectly fine. I will try to find better BMS and stronger battery because here original is very expensive. Thank you for tips man!

[@TheMarcorafael]

Como ficou o indicador de carga após essa mudança?

[@doitgirl]

como o cabo branco fui removido ele não via fazer a leitura, mas se isso for importante pode-se adaptar

[@gopronomad4381]

I just wanna clarify you only connected 2 out of 5 leads? Or paralleled the red and blacks into 2 leads and left the white out?

[@doitgirl]

yes that's right, join the cables of the same color I leave other information : I only used the battery input if you are trying to use the charging input you will need a controller with 5v to 5v input if you want to use direct "charging" via usb. they can also cut a usb cable, shred the red and join in the red cable and the same with black to black. this at the load inlet. I will try as soon as possible to make a new video explaining this.

[@gopronomad4381]

@@doitgirl yup im not connecting it to 5v USb... Im gonna be using a stepdown to 4v- 4.2v, but while im waiting for the board from China, I am currently using an 18650 batt which isn't getting charged (probably because the data cable isn't telling the system about the batt) I unfortunately thrown the BMS so im left with no choice but to just charge the batt manually and or wait for the volt step down

[@doitgirl]

@ツ kroleksius join in parallel ie join the 2 black strands together and the 2 red ones as well. there is no difference are ports for the same channel. I don't remember what it was built for, maybe a separate loading and unloading port.

[@doitgirl]

@@gopronomad4381 sorry i misunderstood the question today i reread it. yes that's right what you asked cables connected in parallel but I made thinking about not loading through the card port. you can also use the board port by injecting 5v with the same principle using a board with micro usb port or using a direct usb type 5v cable or so

[@gamefeel1662]

No need connect the white wire?

[@doitgirl]

There is no problem if it is not connected, but it serves as a control and monitoring

[@carlosduarte6391]

mais facil usar a bateira do iphone 5

[@TheBaonk]

How if we use 2 cell 18650 paralel??

[@doitgirl]

in parallel does not have any problem, only increases the battery life. does not change the voltage, in series can not cause the increase in voltage.

[@eyeringed]

Your vlog is nonsense! You dont even explain how you do it?! You cannot consider it as a tutorial. To understand what you do, your viewers need understanding in electronics? If your viewers has no knowledge at all. They will not understand what u do!!

[@doitgirl]

thanks for your comment first of all it was my first video on the channel and i made some mistakes. second i decided to use subtitles because i'm not good enough at speaking english. third, it is not necessary to know about electronics to do it, I mentioned everything they needed to do and the precautions just need to connect the battery input cables to an 18650 cell paying attention to the polarity, I think most people have some intelligence. Sorry I didn't help you there are many videos if it's not up to you you can simply look for another one, thanks ..

[@eyeringed]

@@doitgirl ok I'm sorry for my bad comment. Now i know that it was your first vlog. Hoping that in times you will improve. God bless u!!

[@doitgirl]

no problem your comment somehow helps me improve. thanks

Como faço para que a caixa de sim carrega a bateria?

[@doitgirl]

boas Felipe esta bateria é recarregada com um carregador de baterias 18650, ou seja e removida para recarregar, se a sua entrada miniusb não tiver estragada é possível recarrega la por ai.

[@felipehelal3782]

A porta USB está boa, porem não carrega.

[@doitgirl]

mas consegues liga-la quando esta a corrente? se não é possível que não notes mas o mini usb esta com defeito ou a coluna avariada. diz-me se liga a corrente para eu te ajudar. @@felipehelal3782

[@kuamhar1936]

Where's the BMS board connection?

[@doitgirl]

you dont need bms ... I think your 18650 battery won't undercharge or have other risks if it doesn't charge directly.. is not a charger port i use a battery port

[@johnnunes4824]

Amigo tenho uma jbl Flip 3 ai a bateria dela deu problema ai coloquei duas bateria 18650 uma 2400 e outra de 3500 mnha porem como minha caixa quebrou o conector de carga fiz uma adaptação por fora porem ela nao ta aguentando mt tempo quando a musica tem mt grave ela desliga sozinha o que pode ser

[@doitgirl]

Nao tenho a certeza mas talvez a capacidade e qualidade de descarga das celulas 18650. Expremente usar so uma de boa qualidade.

[@jls3451]

I used power bank 13k mah and its work but when i full volume theres a crack sound

[@doitgirl]

hello, when opening the jbl and putting glue sometimes the Membrane "black part where there is the logo" can vibrate and hit that glue or other object making this noise, I think that is the problem.

[@jls3451]

Crack sound is fix but i reversed the battery connection 😭 and the new problem is no sound 😂😂😂

[@mattijs20]

why not just buy a replacement battery 8000mAh ? and repair it properly.

[@doitgirl]

In this case the USB port is damaged and it is difficult to find parts and it is expensive. This is an economical alternative in response to the difficulty of finding replacement parts.

[@sunilgurung4028]

can we charge the battery with your configuration?

[@doitgirl]

yes just add a 18650 case and stick it on the body. so you can easily remove and change the battery for charging

[@megandrannaidoo4102]

Why not put in inside

[@doitgirl]

is to big.
