BQ24133: Battery Management and charger/balancer?

Part Number: BQ24133
Other Parts Discussed in Thread: BQ40Z50-R1, , BQ28Z610

Hi all,

What I am trying to do.  Charge a 2S lipo battery pack with balancing and a fuel gauge?  Stand alone preferred but I do have some room on the Micro controller.  Charge rate is approximately 500mA to 1A max.  Although some IC's can charge a 2S packs my first question, is balancing required?.  I do want to this to be a safe device.  Can anyone recommend a series of IC's that can help reduce the circuitry need to accomplish this. 

thank you for your help!
