Working on my Oontz 3 speaker. It suddenly quit playing even though battery charge should have been good. When plugged in to USB charger, charging light does not flash like it should. Took the batteries out-- (2) 18650s, which each show a little over 3.7v.
My initial thought was that the PCB is bad, which is way over my pay grade, but then I wondered if the battery management chip on the batteries might possibly cause this? If possible, how to test?
Thanks.
