I wonder what kind of fuckery I was saved from because of the annoying blinking of the MCU battery charger LED

Photo of 3.7v 13400 500mAh LiPo cell battery with soldered JST connector (ironically, black and red wires are soldered to the opposite colour markings of the battery) with a bit of black duct tape on it. Duct tape hides the small triangle of bulge from the battery swallowing

It’s worth noting that the charger circuit was made so it annoyingly blinks when the battery is disconnected, and the LED is traced directly to the charger IC and can’t be turned off. The only way to make it stop is to plug in a battery.

Since single-use vapes provide a virtually endless supply of free LiPo batteries, I just cracked one open and voilà: no more blinking.

It lasted about a year or something? I wonder what went wrong: is it the charger IC, or are there more corners cut during battery manufacturing than I have in my flat?
