The STIHL 48504405101 AP Belt Bag with Connection Cable is an original STIHL accessory designed for professional users of the STIHL AP System. This robust and padded belt bag allows for comfortable and ergonomic carrying of STIHL AP batteries, distributing weight away from the tool. It includes a connection cable to power compatible STIHL AP System tools, particularly those without an integrated battery slot, such as the FSA 135 or HTA 135. This setup provides extended run times and improved handling during demanding tasks, ensuring a reliable power supply from the belt bag to the tool.
