Internal USB Charging Board / PMU Module
The X10S Express relies on an internal PCB that manages the 5V-to-8.4V boost conversion and cell balancing for the 2S Li-ion pack. This board frequently fails due to thermal fatigue of the boost inductor or voltage regulation ICs during high-current charging cycles. Replacing this board restores the necessary voltage elevation and balancing logic required for the battery to accept a charge.
