CS_P 184 AI
Fuel gauge
detection positive
Connect the fuel
gauge to ground
when not in use.
BAT_THERM 134 AI
Battery temperature
detection
10 kΩ NTC is
supported by default,
and a 10 kΩ NTC
resistor must be
connected to ground.
If it is not used, an
external 10 kΩ
resistor must be
connected to the
ground.
BAT_ID 185 AI
