Faulty USB LiIon/LiPoly charger - v1.2

Post by mjk7ha »

Hi Engineers,

I just got from you USB LiIon/LiPoly charger - v1.2; however when I connect my battery (and battery is YDL 3.7V 2800mAh 623360 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack with JST Connector), the board heads up within seconds and I need to immediately unplug it, aka it seems the charger is faulty, am I correct?
Sincerely,
Michal

Based on the photo, it appears that your battery is wired with the wrong polarity for use with the charger. All of our batteries, chargers and other boards follow the same connector pinout. But there are two ways to wire a 2-pin connector, and batteries from 3rd party sources may or may not match.

For use with Adafruit Lipoly batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
