I have used the zero lipo before with success, however today it started to act strange and the zero will no longer boot. It works fine without zero lipo attached, and fed through the regular USB micro connection.
The blue led indicating good battery on the zero loop board is on as normal. The green led on the zero blinks irregurarly. Here’s a video showing the behavior: https://drive.google.com/file/d/0Bz8mguxaS8ubZnZSS0g0a1hLMGs/view?usp=drivesdk
As you can probably hear, theres also a high pitched noise coming from the zero lipo or from the zero itself. This noise is not present when connected to regular USB power.
