    Hello,

    I would recommend looking at the UC2909 for the charging. it is a switch mode charger that is capable of handling the voltages and currents that you would be looking at operating with for that battery.

    There is also an application note that will help guide you for using this charger in your application. (The UC3909 can be used in the same way as the UC2909).

    The monitoring/gauging I would suggest looking at something like the BQ34Z110.
