Order #3009466-2731831081 - Shipped
Lithium Ion Polymer Battery - 3.7v 2500mAh PID: 328
I just tried to charge it for the first time and my huzzah esp8266 and 32 will not charge it. It also seems to make the esp8266 led flicker when I plug it in. any idea what could be wrong with new cell?
thanks

Re: 2500mAh cell dead
What voltage do you see on on the LiPo when it isn't connected to anything?

Re: 2500mAh cell dead
That's a normal voltage for a LiPo, so we can probably rule out something like an internal short circuit.
Post a photo showing the LiPo and its JST connector please. 800x600 images usually work best.

I have attached it to several huzzah 8266 and 32. non of them charge it or turn on with it. Board also need to be flashed after I plugged in? not sure what else to try? thanks

Sorry for the delay.
What voltage do you see on the Feather's BAT pin when the LiPo is connected?
