Hi, I have some problems with undervoltage when my RPI 3+ is powered by the UPS HAT. This occurs both while the power supply (PSU) via micro-USB is connected or not. I have tried to power the PRI directly from the PSU, and no undervoltage here. The HAT must be the culprit. I'm running a barebone raspian (stretch). The problem becomes worse when I open programs or put load on the RPI in any other way. The yellow lightning icon in upper right corner is almost persistent then. Can you please advise?
