We use on of these designed carriers, for it. Originally it was for an Hitachi, but the 36 Volt Bosch, fits in nicely. I assume, but not checked, bags like this are available, from Screwfix.
Personallly, I prefer the Bosch to the Hilti.
An older person, like me notices the lightness of the Bosch compared to the Hillti!
If you do not have to lug the Hillti too far, then it's raw power is difficult to beat unless you use Petrol drill, which for,obvious reasons, you do not want to use underground, but a very good in the open air.
