This is STihl's AP Battery Bag with Connecting Cord is uniquely designed to alleviate the added weight a battery brings to its tool by allowing the user to carry the battery in the bag and connect to the tool via the connecting cord. This can be an optional accessory for products which feature an on-board battery slot as this will shift the weight of the battery from the tool to the user's hips and shoulders when paired with the AP belt and double shoulder harness or AP battery backpack.
