Bose SoundLink Color II Portable Bluetooth Speaker

[Jagatha]

Hi
My portable speaker, a Bose sound link color 2, all of a sudden stopped and has no life even if I try to charge it, no lights or any chimes. After taking it apart I realized that the battery is not putting out any voltage into the board.

The battery management circuit is a sealed one and I'm trying to identify it. Could you help me to identify this part please? or a possible replacement for it?

It looks like it is a Microchip product that states R700 108T on it. Could not find it online.

Thanks

Forgot to mention that the battery does hold a charge and reads 4.2V. But between the Red and Black wires, it only reads 22mV

Re: Bose SoundLink Color II Portable Bluetooth Speaker

did you manage to fix the device?
ive got the same issue
i found out that the device has a ship mode to prevent the battery from discharging and th get out of it you should holde the PLAY button for 15 seconds while the USB is plugged then disconect the USB, but that didnt work
i wanted to power the device just trough the USB port, without the battery but i cant get it to work i think the chip is disabling the boost converter.
