2500mAh cell dead

Post by AmicusFinch »

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

What voltage do you see on on the LiPo when it isn't connected to anything?

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.

Sorry for the delay.

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