Charged battery indication

Post by tonda2 » Sun Jun 25, 2017 10:29 am

Hi everyone,
I want to make a simple device, which would light a led when my lipo is charged (input is above 4.1V). It should be as small as possible. Does any of you have some good schematic for this? Thanks.

Could I use this circuit but with 4V zener diode?

Well I think it would depend on what powerboost your using? (Assuming your using a powerboost) You should just be able to tap into that, because the Adafruit ones and the banggood ones have charge indicators
