I hope that this is the right place to ask this question:
I am using the Adafruit Huzzah for a project and hooked a LiPo battery to the on board JST connector. To disable the battery when I turn off my application I am pulling the EN pin down to GND via a switch.
So far so good.
I have now observed, that the battery is drained far more than expected after a few days without using and charging my system and I am wondering why. I understand, that the EN pin is tied to a pull up resistor and as a result will slowly discharge the battery over time (when not connected to USB).
But when I measured the current it was around 7mA, which is unacceptable for supposedly disabling the battery.
Here is the schematic:
And here more info about the power management on the board:
I don’t know if the battery charger IC or the voltage regulator allow a small current or if there is something entirely else that I am not seeing.
Does anyone have an idea?
