I want to read the low battery pin on the PowerBoost 1000 and read it with a Propeller MCU. The problem is that the voltage on that pin is pulled high to BAT which can be as high as 4.2v, much too high for the Propeller. So I put a 100K Ohm resistor in series so the voltage would be lower. The problem is that with a charged battery the pin is reading all over the place. It's not staying a steady 1, but randomly jumps between 1 and 0. Is my resistor the wrong size so it's lowering the voltage too much? Should the pin be pulled high as well? Thanks,
Jason

Re: PowerBoost 1000 low battery pin problems
A 100k resistor won't lower the voltage by itself. You'd need another one between the pin and GND to make a voltage divider.
