You can use this pouch with a belt and wear it around your hip or alternatively you can place it in the Stihl backpack. This allows you to operate the Stihl AP tools that require the cord to run them without having to purchase a battery backpack. The pouch has the connecting slots inside which allows you to power the tools using the AP 100 / 200 / 300 or 300s.
This is a great way to use the professional equipment without the price tag of the larger batteries. You can also use this system for tools that allow the battery to be placed directly in them. If you purchase part no. 48504400505 is an AP adapter that essentially is a fake battery that allows the cord to be plugged directly into it. This then removes the need to place the actually battery which carries the weight into the tool, instead you can wear it on your hip or in the back pack instead.
