At arrival i put it directly onto my HackRF ...pressing the Button for 4 sec. and nothing happens.... only the blue LED was blinking. Then i put a LIPO on it. The blinking LED went solid. But nope, still no power on.... (but at least it gives me a hint, that the charge Cirquit is working) Next Step, CR1220 but nope... I took the whole thing to the Place where i work and did some microscopic inspection. It shows very bad soldering ....and finally, by resoldering the output pin from the Charge controller IC -it works great now :D
