Victron SmartShunt connection to Daly BMS

Any suggestions on the best way to run a Daly BMS with a 5/16" connection to the Victron Smartshunt and it's 3/8" connection? Would a 3/8 to 5/16 stud adapter work? Or is there a better way? I may be able to cut and crimp a new connection, but it is a 2 awg wire and there isn't a lot to work with.

So the Smartshunt accommodates multiple wire sizes and the daly is wires?
They don't fit together? In wiring not everything has to be an exact size match. If the components were UL listed the package would list the wire sizes it can accommodate, I thought the Smartshunt would be UL listed.

I love my Victron Shunt....great choice.

Not necessarily the best solution, but I installed an mrbf fuse on the shunt, mostly because I had several on hand.
