Microboost Driver - 1W 445nm (Flashlight)

[Hellraiser]

Hello, I am new here and have one asks. I come from Germany and, unfortunately, my English is not the best one. I would like to pursue the Microboost Driver with an 1W 445nm. Mine asks is: Do I have to do BATT - absolutely with the diode PIN (NOT Used PIN) connect??? Picture 2
Or can I connect BATT - also with the Heatsink?? Picture 1
The flashlight is a Guidesman Grey Laser Host & Heat Sink.
