10. Battery charge cut-off voltage setting: Default 4.2V per cell (standard for most batteries, no adjustment needed). To modify, refer to the RVSET setting table and adjust the board's VSET resistor.
11. Charge timeout duration setting: Default is no timeout. Set via ROT resistor value: 68K - 4 hours, 120K - 12 hours, No resistor - 24 hours. NTC Integration: Not used normally. If required, change NTC resistor value to 82K. Connect a 100K thermistor (B=4100) between the NTC solder point and adjacent GND. LED Indicators: - Red LED: Steady on during normal operation - Blue LED: Illuminates during charging - Blue LED: Turns off when fully charged - Blue LED: Flashes when an anomaly is detected
