- accept config for setPowerMode, setCellCapacity, setCellProfile ( to replace hard coded setup )
- accept value for lc709203f_current_direction_t mentioned at : https://github.com/RIOT-OS/RIOT/blob/df3ab9f16135dca610d81c0286eb23791170b21d/drivers/include/lc709203f.h
- TODO low priority because no resource/application for me---------------------
- capture values for getThermistorBeta, getCellTemperature
- accept config for setThermistorB, setTemperatureMode, setAlarmRSOC, setAlarmVoltage
