Hi everyone.
I found attached schematic for a Li-ion battery charger. (My battery has 4 cells of 3.2V, 3500mAh).
But, after do a search of info, it looks that Li-ion charge must be a controlled process wich has different stages.
I built the ciruit below for doing measures, and the current sourced by the 317 is under current specified in the battery datasheet.
The battery seems to be charging, but very very slow.
The charging time semms to be much longer that specified in the datasheet with this circuit but...
may the circuit damage the battery or affect it in anyway?
Thank you.
Regards
