Good day
Ive this li ion battery pack from a LOGITECH UE MEGABOOM speaker, with 10 pin connector.
I indetified 5/10 pins. Red is positive 8.4V max, black is GND, white trigger (when grounded, the battery is on).
The others I suppose are triggers to:
Ive checked these pins to GND, nothing. Also with a resistor. The same with V+. Ive measured voltage, nothing.
So, the battery pack BMS senses the node betweed cells.
The speaker instead sees only 8.4V. At ~6V it shut down. At ~6.5V gives the low battery allarm.
I'm interested to understand this BMS to use it. If not possible I will swap to a 2pin (v+/gnd) BMS.
I'm not sure would be safe to use an unknown BMS, charging + and GND directly with 8.4V, while white ON-TRIGGER is GND. For the expense, would be easier to remove it completely.
Thanks in advance

The others I suppose are triggers to:
- power off the speaker
- allarm of low power
- faulty battery
- recharge mode
