I watched youtube video of guy taking it a part, you have to actually brake it, it's glued all around.
By the time you are done with it, it's a mess.
When I faced that error message, I tested two more batts and I got same error msg, so there was no way all 3 battery's went bad at once.
On top of that, $15 board is allot cheaper to replace then $90 battery, right?
If anyone need that job done, and willing to ship it to me, pay for shipping back and forth and buy a part, I'll be happy to do soldering job.
Just PM me
