Why This Tool Is Worth It
Running out of battery in the middle of a project is never fun. Two extra 4Ah packs keep you working while the others charge.
These use a single layer of enhanced 21700 cells, plus copper end plates and power rails for reduced resistance. Bosch’s CoolPack 2.0 technology helps them run cooler and last longer than non CoolPack Bosch 18V batteries.
At just 1.10 lbs. each, they keep your tools light without giving up power for drilling, grinding, and cutting.
