Di2 BM-DN100 external battery mount

Anyone know if the BM-DN100 external battery mount allows the battery to be charged and the firmware to be updated from Junction A like the BM-DN110 internal battery?

I have a BMC TM01 time trial bike which comes with a door in the seat tube near the bottom bracket for use with the external battery mount.  It puts the external battery mount and battery inside the seat tube.  I'd like to be able to charge the battery from Junction A like the BM-DN110 internal battery and was wondering if BM-DN100 allows that.  The other option is to just get the BM-DN110 internal battery and figure out where to put it.  Giant makes a BM-DN110 seat tube battery mount for tear drop shaped tubes.  I don't know if it would fit a BMC TM01 seat tube.
