  • Not sure if someone had this happen to them but when I plug in a LiPo battery charged to 4.5V it outputs 3.7V and gets really hot. And when trying a 9V battery (to see if the reason the output was 3.7 instead of 3.3V due to a lower input voltage) I ended up with 7.24V and it got REALLY hot really quickly (to no surprise). Anyone have similar issues?

No public wish lists :(
