  • Page 16 of the data sheet gives a formula which implies that a 110 mohm resistor will give a 1000 mA charge current. Your schematic shows two 110 mohm resistors in parallel which gives an equivalent of 55 mohms. According to the data sheet this would give a fast charge current of 2000 mA... way too much. Maybe the photo is right and there is only one 110 mohm resistor after all (???)
    This charger will work on Li Ion batteries but will under charge them by about 10%. These want to be charged to 4.2V versus 4.1V for Li Polymer.

No public wish lists :(
