#63617 Hi i am newbie and sorry if i ask something asked before. (I did some search but couldn't find)

I am using NodeMcu ESP8266 development kit and I am using LiPo battery (3.7V 1850mah). While i was using 3.7v 500mah NiMh battery i could charge it via usb and use esp8266 at the same time. But when i tried it with LiPo battery there was a smoke and i unplugged it immediately.

Is this happen because i use LiPo battery or i did something wrong?
