| Pin | Signal Name | Function | Typical Voltage/Logic | |-----|--------------------|--------------------------------------------------------------------------|-------------------------------------| | 1 | | Battery positive terminal (cell series output) | 10.8V – 12.6V (3S Li-ion) | | 2 | B+ (sense) | Redundant positive sense line (for voltage drop compensation) | Same as B+ | | 3 | SMBC | SMBus clock line (I²C-compatible) | 3.3V pull-up, bi-directional | | 4 | SMBD | SMBus data line | 3.3V pull-up, bi-directional | | 5 | TH / T | Temperature sensor (NTC thermistor, 10kΩ at 25°C) | ~0.5–2.5V depending on temp | | 6 | NC or ID | Not connected (or battery ID resistor for charger detection) | 4.7kΩ – 10kΩ to ground | | 7 | B- / GND | Battery ground | 0V | | 8 | B- / GND | Second ground (current return for high power) | 0V | | 9 | B- / GND | Third ground (safety/redundancy) | 0V | Sometimes used as a "detect" pin; often must
