Hey Andrew,
I use the Bosch HTH181-01 18V. It has 500 ft lb or 677 nm of torque. Had it for about 2 years and use it up north for concrete bolts and shed builds.
All our 1/4" rattlers are bosch too and they all cop some pretty severe treatment.
We ran Makitas but now all our cordless gear is pretty much Bosch.
