I used 18650s too but only difference between your method and mine is that I didn't have to MOD the battery compartment. But I like how you made batteries look like they came out of a factory, looks a lot more cleaner and neat compared to mine. Awesome work!
Taylor Soloai my batteries didn’t fit without modifying the case. There was a 1-2mm gap when you put the lid on, and you try to avoid any physical pressure on those batteries. Then again, as long as it works.

not sure what there is to explain? how is it different than others? The original battery has two pouches, my setup has 2 sets of 2 batteries in parallel, and the wiring is the same as the original battery pack. And btw this setup works in my speaker since i made the video, and that is 2 years now.

Hi, thank you for this demonstration! I have done the above with some Samsung 3500mAh batteries. How have your batteries held up? Are they still keeping a charge after 4 years? Ive noticed when charging mine that the indicators go from 1-4 very quickly and also from 4-1 very quickly. Have you noticed that your battery level indicator is now less accurate?
not really, mine still works great. Make sure you have real Samsung batteries, there are counterfeit cells out there. And it takes only one bad cell in the pack to make the battery pack behave weird. And what do you mean by very quickly? How long does it take?
Do you get JBL xtreme distortion at full volume.? i got some distortion . sounds like clipping,after battery replacement 18650.But only when i listen music on yotube music or songs from my phone with hight quality 320kbps
What did you use to cut the piece of plastic that doesn't let 18650s to fit?Should i take care of anything?|I am charging to full at the moment with the speaker assembled, the door doesn't close good so there is air leak and distortion at the bass, i was wondering if would good to mod it, i will check how much it lasts with the 18650s and if is a big improvement then i will go on
@mygiguser I accidentaly ordered a new battery for the xtreme 2 instead of xtreme. Could I just trim up the battery spot like you did and put in the xtreme 2 one?
the battery in Xtreme1 has 5 pins, and the battery in the Xtreme2 has 6 pins. So the answer is no. You would have to rewire that new battery pack to get the connector right.

you need to build the battery the same way the old one was. the 3rd connector may be for temperature monitoring, and the whole thing may not work without. But the XB30 battery is already made from 18650s? Does it make sense to just buy a new battery pack?

26650 doesnt fit, and why are you questioning the green? Green is shown in the schematic because it is necessary. I dont understand why you question that? Also 5000mAh may be too much for the BMS, the max for a 18650 is 3000mAh as far as i know, everything higher is fake.

How we can use suatable BMS for 18650 ? Original xtreme bms cutting out earler `cose maded for LiPo batts. 18650 will last longer, but need to replace bms as well. Dont know why and for what they use to use 3rd wires after bms. As usual two is enouth. Bms after bms?
Did you see the drawing @2:44 in the video? That is how it is connected. The connector to the main board has 5 connectors two GND, two power, and the one in the middle is Temp.
Nice work! Can you see any problems with having more batteries installed? I'm planning too putt batteries, in both sides under the air thingy, aswell as we're you put youre batteries, will the charger mange it? I know the sound quality can be an issue... I just want to maximize the battery life, for like festivals or camping usage. Great video!
If you add batteries in parallel, that shouldn't matter as long as you don't run out of space inside. I am sure the sound will change, if you use up all the space inside the speaker.
i was planning on doing thia to increase the capacity i just wanted to add 2 more. i have 3000 mah batteris so if i wire in parallel that geta me up to 6000 if i add another 2 that gets me to 9000 right??
@mygiguser can you explain?? why you put the batteries in series and not like the original configuration 2x parallel ?? second question: does the green wire connect on the BMB on both BM contacts??
Ok let me change the question so you understand it better , the original configuration was two flat batteries independent connected to the BMB. why did you made one batterypack out of four batteries and not two packs of 2 batteries? And connected them the same way as the flat ones
Hey giguser thnx for the help my jbl works properly now, for increased battery life instead of 4 I placed 8 batteries (4on each side) Jst one issue when charging after 30 mins the 4th led starts blinking and after tht it reaches the 5th led then 1hr later again 4th led starts blinking and it goes on forever. While playing I get a very large playback time, but how would I knw tht batteries are fully charged coz 4th led starts binking and goes on forever also would like to knw is there anything other wrong with it coz my batteries I used were of good quality

Hello, after the mod I got a little distortion on the side of the pasive radiator that is taken out when reaching low frequencies, what could it be. I tried to tighten up the bolts that hold it as muchs as i can and it seems it helped a little but I cant figure out what reaaly could be the problem.
Well when you have a brand new great battery this charge indicator may work. Once the battery was in use for a while it is more and more likely that the 5th LED stays on, because that kind of battery looses its capability to charge 100%. And the 5th LED shows the 100%. I don't think it is a big deal.
I have a problem with my jbl xtreme I just bought a battery for my jbl it won't charge up at all and it won't play unless it's plugged in and even then it still turns off, and just to let you know it was doing this before I put a new battery. So please help me what do you think is going on with it?
If it is not the battery then it could be the power supply? Can you check the voltage when the power supply is attached? Maybe it doesn't have enough power?

update on jbl charge2. i was able to salvage d pcb board on the swollen lithium ion battery of my jbl charge2. at first i was very hesitant and afraid to remove the board. i carefully peeled the shrink tube that was covering the battery also tried not to damage the body of the lithium battery to avoid sudden fire. well im very thankful that nothing happened that time. i swapped the old battery with a single 18650mAh 3.7V. as of this moment my speaker is working again.. i suggest not try or risk the same way i did if you dont have any small knowledge about electronics.
Bro there is one more problem after I connected everything and closed the JBL after playing it the bass sounds wierd some people say there is air leak but don't know from where the air is leaking or which part to seal pls help
Yash Dobra did you remove some of the battery compartment so that the new batteries fit 100%? If not, the door doesn’t close and then air leaks! There are not many spots where air could leak, but the battery door has to close all the way!

Dear, it is assumed that when installing the batteries has more mA than the origianal, how does the led behave according to the load? Is there a problem if I install samsung batteries 18650 3500mA? How long is the battery life in operation with the new arrangement?
Jose Ramos Ramos no problem with the LED charge indicator, it is based on battery voltage. The more Ah the new batteries have the longer they last. Battery lifetime is hard to say, it depends on the battery quality. I think Samsung is pretty solid.
Wenn ich 4x18650ga nehme mit 3500mAh bei 3,6 Volt habe ich 7Ah bei 7,2V also ~50Ah. Ist das Problematisch denn der Lautsprecher maximal 40W im Netzbetriebt leisten kann? Beim Originalakku bleibt man ja bei 37Ah. Hoffe du kannst mir helfen. Danke und super Video

@@mygiguser the green one, that negative, seems to me being in the positive and negative in the board. And once again, great video im going to do the same saturday with my jbl. Thanks
Agreed, wiring is not the same as original batteries, couple other videos confirmed correct wiring, nit like this video
What firmware version is the best for jbl xtreme ?
Hey, I’m trying to do the same with the boombox 1 and i found they are 4 cells not 2 and the BMS is like a double of the one on the xtreme so could you please tell me how to connect? Should i get 8 batteries 18650 ? Or only 4 ? Please help
doesnt boombox one have 18650s? i think its safe to get a new battery of ebay.
No it’s not unfortunately it’s liPO battery i guess
Could you please send me your facebook profile or anything so we can chat on ?
I made the change, it was running for 8 hours, but when I plugged in is going to the 5th led and blinking non stop.I removed the charger and is not turning on animore. Is turning on only when you plugged in the charger.Help please !
Why not make a wire with plug going outside, so you can connect and disconnect multiple batteries ?
Make a fake battery pack inside to keep the sound the same
because it is ugly
Can I use 4 18650 3.7V batteries each?
Vitor_ isn’t that what i used?
@@mygiguser so using 4 battery is 14.8v! right
Depends on how you link them
Good day sir..Can i mod it to a motorcycle battery?..does it safe?..thanks if there's any reply
Ramon Tulfo maybe, but li-ion has more power
@@mygiguser thanks sir..i'm planning to do it😁..will it burn the board?..i think there's no thread here in yt anyone trying to do it on motorcycle battery..btw i'm filipino..hope you understand my english
Nice job. Great idea to reuse some old batteries that are still good! Voted 👍
mygiguser can i use 21700 or 20700 batteries for that mod?for more runtime.
Hello, after the mod I got a little distortion on the side of the pasive radiator that is taken out when reaching low frequencies, what could it be. I tried to tighten up the bolts that hold it as muchs as i can and it seems it helped a little but I cant figure out what reaaly could be the problem.
Wires touching surfaces can cause distortion/rattle..
I will try this. I have 18650 4x 5000mah..thank for this video..
there is no such thing a 5000mAh 18650, that sounds fake. Where did you get those from? China?
@@mygiguser no.. I took from broken samsung laptop. And Ialso have 3500mah
@@BLACK_HEART_1993 How is it working for you mine are 4200
I already replaced with 18650 battery but the problem i already charge it for 12 hours still it wouldn't got full what's seems to be the problem?
how many volts should be the battery of JBL XTREME?
7.2V and 8.4V max ua-cam.com/video/PrKXumAvC8g/v-deo.html
@@mygiguser tnxs for the answer, so cannot put 14.8 volt right?
@@mygiguser how many volt each battery that you use here in your video?
No you cannot, that is way to much voltage!
@@mygiguser can i use 4 pcs of 3.7 volts each battery?
Ok. I've seen people with that it keeps blinking with the fifth led. Why is that and what could you do about it?
Well when you have a brand new great battery this charge indicator may work. Once the battery was in use for a while it is more and more likely that the 5th LED stays on, because that kind of battery looses its capability to charge 100%. And the 5th LED shows the 100%. I don't think it is a big deal.
I have a problem with my jbl xtreme I just bought a battery for my jbl it won't charge up at all and it won't play unless it's plugged in and even then it still turns off, and just to let you know it was doing this before I put a new battery. So please help me what do you think is going on with it?
If it is not the battery then it could be the power supply? Can you check the voltage when the power supply is attached? Maybe it doesn't have enough power?
Defective battery
A bateria original são duas células de 7,4v 5000mah em série, então nessa adaptação as baterias vão ficar com 3,7v???
Ai tá em paralelo e em série!! Ai vai ficar 7,4v !!
Oi boa tarde como faz na boombox 1
Bem, você tem que desmontar tudo. É mais fácil comprar uma bateria nova no Ebay e depois assistir ao meu vídeo aqui:
ua-cam.com/video/bS7SdO_4nWE/v-deo.html
Ela já dá desmontar
Tem como vc falar como fazer
Hi bro. Very nice video. Nicely explained. I have one question The original battery is 5000mA 7.2V, I am planning to put 6 no’s of battery, each battery 1.2 V(AA) 1300mA. Battery size 6 no’s fits very well , Is is possible to connect 6 no’s AA battery in series to the circuit?
no it is too long
After ive done this, when fully charged, the led lights are not lit anymore, is that normal?
Jay ar Zamora only if the batteries are fully charged. Otherwise some should be on while charging.
Warum haben sie den bm anschluss gebruekt ???
How many hours can you listen to
hi.. is your diagram of battery is correct??
Oh yes, it still works fine. I know what I am doing.
hi,do anyone know solutiom for xtreme 2?,because theres a yellow and white cable,the white cable with 10k resistance not works,been changing the battery cell with original bms board but the bms didnt showing output power
the xtreme 2 has already Li-ion batteries, you can buy a complete pack with bms
the battery itself here was way to overprice, the price of the battery are like as the speaker itself sir,cant turn the speaker without battery😢
is there a way to use the speaker without battery,sir???
i bought some to do on my charge 3 im confused on the rating of the batteries they are rated at 3000 mah 3.7v is that each cell or for both?
WCxColossus each cell
@@mygiguser so with 2 cells ill be at stock mah for my charge 3?
can you show how to do like this for JBL Bommbox ?
The bms is dead what I do, HELP ME!!!
buy a new battery from ebay
In india right now. God 😱
1:39 Those magnet does not conduct electricity. Therefore, there is no insulation on the connectors :D
Weißt du ob die Xtreme 2 den gleichen Akku drin hat?
Bobby Xtreme 1 hat Li-Po Pack und Xtreme 2 hat Li-Ion Pack
So good..i follow wat u do and its work it..thankyou so much sir..here in phillippines
hndi nmn ba mabilis masira paps?
ako naman jbl charge2 kinuha ko lang yung board sa lumang battery. isang 18650 na batt with 3.7V so far so good hehe
Boss 18650 b n 3500 mah at anong brand?TIA
So, perhaps show how you got the case opened up instead of just skipping over it.
Thnx for the gread video i was able to fix ky jbl xtreme that i had put a way for a year.
update on jbl charge2. i was able to salvage d pcb board on the swollen lithium ion battery of my jbl charge2. at first i was very hesitant and afraid to remove the board. i carefully peeled the shrink tube that was covering the battery also tried not to damage the body of the lithium battery to avoid sudden fire. well im very thankful that nothing happened that time. i swapped the old battery with a single 18650mAh 3.7V. as of this moment my speaker is working again.. i suggest not try or risk the same way i did if you dont have any small knowledge about electronics.
Bro there is one more problem after I connected everything and closed the JBL after playing it the bass sounds wierd some people say there is air leak but don't know from where the air is leaking or which part to seal pls help
Yash Dobra did you remove some of the battery compartment so that the new batteries fit 100%? If not, the door doesn’t close and then air leaks! There are not many spots where air could leak, but the battery door has to close all the way!
@@mygiguser ohhh crap! There's not much space there . That's why the door doesn't close fully , just some space is left it doesn't close dude is there no other way that I can seal it ?
Ok so now everything is done correctly just while charging the 5th led keeps on blinking after keeping it charging for a very long time also it keeps on blinking idk what to do pls help tell me when to stop my charging my
Yash Dobra measure the voltage of every single battery, are they all the same?
@@mygiguser so I checked the voltage of 2 batteries when I checked after charging was 3.87 and other two batteries was 3.72 this was it.
U said there are ready to buy batteries for replacement but i only find Lithium Polymer batteries, that are different batteries, LiIon like u use have much more lifetime even if you store it with 100%. :)
That's correct, but if you buy a ready made pack, you don't have to modify the case and you don't need to solder. Not everybody wants to do that.
Great ideas sir
Nice work man. Can I follow the same method for my Harmon Kardon Go Play?
Can you do a video on HK GoPlay battery upgrade too?
banubash not sure, i don’t have that speaker
What size of battery wrap did you use on this video?the one you use to make 4 batteries
I found it on Amazon: Uxcell a15012900ux0431 PVC Heat Shrink Wrap, for 2 x 18650 Battery, 10 m, 50 mm Width, Red
Dear, it is assumed that when installing the batteries has more mA than the origianal, how does the led behave according to the load? Is there a problem if I install samsung batteries 18650 3500mA? How long is the battery life in operation with the new arrangement?
Jose Ramos Ramos no problem with the LED charge indicator, it is based on battery voltage. The more Ah the new batteries have the longer they last. Battery lifetime is hard to say, it depends on the battery quality. I think Samsung is pretty solid.
Can I do that to my JBL charge 3? What's that a combine of parallel and series connection?
No, not enough space in the Charge3, and yes parallel and series!
What is the voltage of that connection? I thought that jbl extreme is only about 3.7v
plss. can u make this for JBL chagre 2 + with 3.7V battery
Sorry they 18650 Li-ion don't fit in any Charge speaker.
I did without cut internal body just punched n screwed no air leak working perfect from india
I love dis video
I am an engineer I do dis all always but today was bad for me I Couldn't do for extreme 3 jbl can you me

Sou brasileiro tem como vc vender uma bateria dessa pra mim
Desculpe, não. Existe Ebay no Brasil?
I did it on mine and it worked.
Eu fiz no meu e funcionou.😁

Não aceita solda

Wenn ich 4x18650ga nehme mit 3500mAh bei 3,6 Volt habe ich 7Ah bei 7,2V also ~50Ah. Ist das Problematisch denn der Lautsprecher maximal 40W im Netzbetriebt leisten kann? Beim Originalakku bleibt man ja bei 37Ah. Hoffe du kannst mir helfen.
Danke und super Video
Das Netzteil hat 18v ist es also doch möglich dass der Lautsprecher mehr als 8,4v verträgt?
Der Strom wird vom battery management board an der Batterie geregelt und limitiert. Ich glaube nicht dass es dort zu Problemen kommt.

Молодец, я звук выключила и просто посмотрела, нормально все понятно как делать
вы молодец, а то большинство мужиков тут в ступоре от загадки зеленого провода)
Супер!
When you make the battery pack, what size nickel strip did you use and where do you get them?
nytrhythm i don’t remember, but i got it from Amazon
