PulseX BT speaker Battery Management Chip (BMS) Reset/check

just a quick attempt at a sorry ASMR type video. Battery on this would not charge and it only worked on the charger. Turns out it had two 18650 lithium cells with a 2S BMS chip. Voltmeter said no continuity to the negative terminal that plugs to the main chip. after poking around with the Continuity test to see where the current was being cut off. it started working again. I dont know why but if you do. please tell me how some small current reset the logic on this controller.

enjoy the speechless run through!
