Hi

Hope you can help me with this. I have an UPS3 board on a raspberry pi 4 and a 3,7v 6000mah battery attached. It works. but there is a red led for ac input power and a green for battery input power. first they both lit up and after a couple of day the red ac light began to blink. what does this means? If I pull the ac power off and attached it again it will light up steady and then after a couple of days it will start to blink.

best regards Robin Petersen
