    I assume your pack is 1-4s since you are using bq24735 for the charger.

    In that case you can look at bq40z50-R2 for a gauge to put inside your battery pack that will perform the gauging, safety protection, and cell balancing functions.  It supports 1-4 series cells.

    If you cannot put a gauge inside your pack then you can also look at bq34z100-G1 which is a bolt-on gauge that can support any number of series cells but it does gauging only.
