JBL Extreme Battery Replacement Lipo to Li-ion

Hello, i just did this battery replacement and it works! I will give some more info. I replaced the Lipo for the LG INR18650-HG2L 3000mAh - 20A which costing around 50% less than the brown ones in the demo. And another very important issue i was dealing with, my battery pack was slightly to big for its chamber caused by wiring. Therefor the lower lid could not seal properly and AIR was leaking when playing music loud. So resonance distortion was the result. I almost gave up, thinking my speaker was blown. So keep in mind the casing must be sealed completely!!! I used EPDM kit at the base of the inlet cable assy battery pack. Succes everyone, succes Léon

The confidence you have while you disassembly that device is astonishing. I'd be afraid of breaking clips and stop immediately.

you should add foam for the battery compartment, so they dont rattle while playing music

Please do more such videos.. you are the Battery King

Those Batteries need to be isolated with soft material. Otherwise the sound will be soon or later bad because of their vibrations mate.😊 Otherwise good job👏🏿👏🏿

I did the same with my xtreme except that I used Samsung Lithium batteries. I like the Panasonic ones though. This was a fun project for me at the time. Great work on yours too.

I like your videos because I can feel the love and respect you give to all the items you repair. As if they were alive.

Thanks to you. I understand how to use the bms on this device. Every one needs to not throw away their battery powered items but to repair them their self. "Gear show" shows how we all can make a difference.

Great job. One thing I would like to ask why we should use 2 yellow cables to join the pcb (BM) to the battery. Could we simply join the two BM points on PCB and use a single cable to connect it to the battery?

Estupendo video sobre el cambio de bateria de este JBL Extreme de tipo Lipo a Li-ion, respetos y saludos desde Venezuela. 💯💯💯💯👍👍👍👍👍🤘🤘🤘🤘🙏🙏🙏🙏💯💯💯💯

And the water resistance?

You haven't put back the rubber gasket. Not only this use for waterproof but also help to airtight the internal to produce more vaccum to help create more bass in low frequency. Thats a very useful one. The JBL portable series are marvelous engineering of speakers.

Did this 2 years ago... But never ever it will fit like you shown or the shown xtreme isn't sealed anymore. The passiv speakers loose a lot of power if this case isn't correct sealed. I had to remove a bit of cover both sites to get the seal close enough together with no little air gap. Other option would be to seal the hole and let the encloser with this gap.

I'm a bit suprised, i did many conversions like this, but the 18650 cell pairs did not fit inside right away, without some dremeling. Also, if you planning on using the speaker for years to come, you should definetly put in a 2s balancer. The lack of it, in the original bms is what causes the lipo cells to die so soon.

Thank you very much for such a great detailed instruction. I can disassemble the device but I cannot solder. I never had to deal with soldering. Is there a direct replacement of Li-Polymer battery?

Thanks a lot, I did that on my Xtreme and worked PRETTY FINE, about 11 hours duration using high quality cells.

I've done it too, it works way better than the stock battery 😎👌

I did nearly the same with mine, but i used again a lipo. Great vid!❤️👍

Nice upgrade. I hate that startup/shutdown sound. It's silly and annoying. You can turn it off by using the JBL app. I've done on mine - now it's quiet.

QUE SE VE FÁCIL HACER LO QUE TÚ HICISTE. FELICIDADES. SALUDOS DESDE CHILE.
