Bosch 4.0Ah Battery Kit

The Bosch 18V Starter Kit provides a reliable power foundation for professional cordless fleets using the Flexible Power System.

Built for the Job

Contractors and installers require consistent uptime to maintain project schedules. This power set addresses that need by utilizing 4.0Ah cells that balance weight and runtime effectively. The battery is light enough for sustained overhead drilling or repetitive fastening while providing enough current for heavier tasks like circular sawing or grinding. Since the system is modular, site supervisors can swap this power source across dozens of different tool skins, reducing the total cost of ownership for the workshop. The charger features a compact design, making it easy to store in a L-BOXX or mount on a workshop wall to save bench space.

• Powering heavy-duty cordless drills and impact drivers for timber framing.

• Running cordless angle grinders for metal preparation and deburring.

• Supporting high-draw rotary hammers during masonry and concrete drilling.
