I have a LilyGo T Call with a SIM800H and when i try powering it with a lipo battery it doesnt turn on. I have tried pressing the button and it doesnt do anything. I tried measuring with my multimeter and noticed that while the IP5306 was getting 3.8V on the Vbat, it was only outputting 2.2V on the Vout. What could be wrong?
