STIHL ADA 1000 Dual Battery Adapter (6909 400 4300)
STIHL ADA 1000 Dual Battery Slot Adapter lets you use up to two suitable AP batteries sequentially in the STIHL RMA 765 V lawn mower or an eligible BGA 300 backpack blower. When the first battery is depleted, automatic changeover switches to the second battery, helping reduce interruptions during longer jobs.
Key Features

- Adapter weight: 1.9 kg, excluding batteries.
- IPX4 protection against splashing water from all directions. Follow the operating instructions for wet-weather use, cleaning and storage.
