After having burned a small hole in my finger, I'm trying to figure out why exactly the Micro-Lipo charger heated up instantly.
I am using the Adafruit Micro-Lipo charger
which has the following specs:
3.7V/4.2V LiPoly/LiIon 100mA charge rate default Short jumper for 500mA
I had connected a 3.7V 1200mAh battery to the terminals where the entire board heated up instantly. The battery is an uxcell 603450.
Was this because the mAh rating on the battery was way too high? There was no power source connected to the MicroUSB port on the charger.
If it is the size of the battery, how do I calculate what size charger I need in order to charge 3 of the 3.7V 1200mAh batteries wired in a series?
