My JBL Xtream 3 has stopped working so I replaced the battery with 18650 batteries. it worked for 1 month and again it failed. it cant be turned on without a charger. Then I realized it was the BMS Board. To replace the BMS board with HX-2S-A10 BMS Board

, I couldn't find any Diagrame to that 6-wire connector that JBL Xtream 2/3 has. Especially the middle white and yellow wires.

As in the picture attached white was connected to the D and yellow to the C. Black to the P- and red to the P+.

Can you help?

So I got myself an Extreme 3 speaker, that had stopped working after being dropped in a swimming pool. Yes it was an impulsive buy.

It powers up and connects to my phone, but no music or sounds come out of it, including no sounds when it connects n powers up/down. The volume button on the phone and speaker communicate with each other. The battery doesnt hold charge either.

Question is, whats the chances of problems being resolved if I replace the main board and battery??

Or does anyone else have any other suggestions?

Any help is much appreciated, thx in advance

I have this JBL Xtreme 3 which was rarely used. i connected a small hand fan through the power bank function of the speaker and since then each time i turn the speaker on, it shuts down within 5 seconds. i have tried the reset options but no luck.

uhm,the problem is,when i was connecting the speaker directly,it doesnt showing any sign,but when im connecting the dead battery,the speaker blinking red and looks like low battery,JBL Xtreme battery mod doesnt work because it have 6-battery pinout (Red-Red-Yellow-White-Black-Black),and i cant use the speaker right now,

while checking the voltage,it seems charging the battery with 19V itself,is this right?,because the battery specification are show 8.4V Maximum.

trying using the lower voltage (12V) adapter shows blinking red and i can powering on the speaker for just a sec until the speaker turn off like its low battery

this is weird problem

do i have problem with the unit?,because the warranty already void,
do i have someway to just use this speaker?,

is there any jumper way or replacement kit for the battery or what?,
theres no battery mod for jbl xtreme 2 on the internet

thanks for reading and replying,
