Replacing BMS board and batteries
I changed the battery in my JBL Xtreme half a year ago: [SOLVED] Horrible sound after battery replacement.
The speaker was working perfectly up until now, it seems to be very inconcistent with charging. When I opened it up I saw the whole BMS board was oxidized. (From using too much flux)
There's a video about this by Abrar Akram that explains it in more detail: LINK
These are 2 compatible boards that can be found on Aliexpress that are very cheap 'HX-2S-D01' and 'HX-2S-A10'
I made a diagram for the wiring, 2 sources confirmed this to be correct.
I will post pictures of the result.
Questa è una buona domanda?
