The Makita BDF451 is a driver-drill combo kit powered by 18V LXT lithium-ion batteries that offer 280% more lifetime work and twice the number of cycles, providing longer run time. With a built-in CPU chip in the charger and another in the battery, the batteries and charger communicate throughout charging to get optimally charged in 45-minutes. The charger in Makita BDF451 also features "Active 3 control" for current, thermal, and voltage controls. The driver-drill has 16 contact terminals that ensure firm holding for providing constant high power. The built-in fan in Makita BDF451's charger cools the battery and gives it a longer life. The compact lightweight body that weighs 4.6 lbs and measures 9-3/8" in length makes the driver-drill combo kit comfortable for prolonged use.
