Thanks to the new LiHD technology, Metabo is the only manufacturer in the world to cover the entire power range from 400 to 3200 watts. Applications that were previously reserved for the most powerful corded machines are now possible wirelessly. The 4.0 Ah battery packs are perfect for all drills, impact wrenches, and rotary hammers. They are the only 4.0 Ah battery packs with a single cell series, making them significantly flatter than other 4.0 Ah Li-Ion batteries, 100 grams lighter with improved ergonomics, and even more powerful. The combination of innovative high-performance cells and completely newly developed components of the LiHD battery packs ensures ultimate performance and extremely long usage with minimal temperature development. The interplay of many technologies, such as intelligent battery management, contributes to efficiency.
