Note: Must be used with battery belt or AR-style backpack battery and required adapters purchased separately. The Lithium-Ion battery-powered BGA 100 is built with the professional landscaper in mind. When in boost mode, the BGA 100 is the most powerful dedicated handheld blower in the STIHL range. Instead of an on-board battery, the BGA 100 uses a battery belt or AR-style backpack battery, meaning a lighter blower and easy handling for the user. To deliver the optimal balance of power and run time, the BGA 100 features four performance levels through a variable speed throttle trigger. As the quietest blower in the STIHL lineup, the BGA 100 is ideal for use in noise-sensitive areas. This high-performing, durable blower will guide you through routine lawn maintenance, leaf and debris cleanup, and many more landscaping tasks.Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.
