Hello,
since my profession is testing mainly Li-Ion batteries I would like to remind you that the usage of those batteries can be very dangerous under certain circumstances.
Due to misuse or productions failures a thermal runaway situation can occur, causing at least smoke or even fire.
So in the best case you have in addition to the charging IC a separate surveillance IC for over- and undervoltage, as well as overcurrent and overtemperature.
This are some crucial points what ISO62133 demands for portable Li-Ion Batteries.
And please don't buy some cheap cells, as they won't have the rated capacity and there is some danger of bad production.
