Is there a a way to add low power led to lip ply charger 1.2

I use the power boost 500 which has an indicator when voltage in battery drops to 3.0 or 3.2.

Is there a way to add a similar indicator to the lip ply charger 1.2?

The MCP73833 charge controller chip does not have a low battery detection circuit. You would need to add some external circuitry to monitor the voltage and light the LED. There are some example circuits here: https://www.eleccircuit.com/simple-led- ... ttery-low/
