I am contemplating a new design which uses an external BMS such as the 5v DFRobot device. It appears from other comments that the proper connection is to plug it into the solar input of the 19007.
My question is if I can then use the USB port on the 19007 for a data connection and flashing while the BMS is plugged into the solar port without somehow causing an electrical conflict back to the BMS.

You can of course supply from USB and solar panel at the same time.
The different inputs for power supply (USB, solar panel, external supply) are protected and the one with the highest voltage will supply.
