bq24735 and the bq40Z50 for Lithium Ion battery Management

Hi,

I wish to use the bq24735 and the bq40Z50 for a 4 cell Lithium Ion battery system. I have ordered both EVMs. I wish to clarify

1. If I can hang both the bq40zEVM and bq24735 EVM  off the battery pack and they basically work independently. Is this correct?
2. If  the power to the system is routed via the bq24735 board and that if undervoltage occurs the bq24735 will disconnect the load. Is this correct? 

Thanks
