I intend to connect a 240mAh 1S 3.7v 25C LiPo Battery with a 5V Step-Up Regulator to the Arduino pro mini v5 VCC pin bypassing the linear voltage regulator.
But the battery datasheet says "Never discharge Li‐Po battery below the Lowest Discharge Voltage 3v per cell"
and the voltage regulator data says "takes an input voltage from 2.7 V to 11.8 V and increases or decreases the voltage to a fixed 5 V output'
Thus the Voltage regulator will discharge the battery to 2.7V causing irreversible damage which will deteriorate the battery performance and cycle life.
If I disable the Arduino on-board power LED and since I am bypassing the Linear regulator in sleep mode the current consumption will be 0.0058 mA, so if I use the SparkFun LiPo Fuel Gaugeprogram and program the Arduino to enter sleep mode at 3V will this be good enough to protect the LiPo battery?
