The Black & Decker LCC300 20V Max String Trimmer & Sweeper Lithium Ion Combo Kit features a 20V Max Lithium Ion battery which offers a longer lifespan and retains its charge 5X more than similar NiCad batteries. This kit includes (1) 2.0 Amp hour lithium battery pack for 33% more run time per battery pack than our previous LBXR20 pack. This unit is two-tools-in-one: a trimmer that easily converts to edger to cut along sidewalks and driveways for a clean, manicured look. The string trimmer has a 12" cutting swath and features an exclusive gear drive transmission which delivers more cutting power to get the job done faster, along with an Automatic Feed Spool which ensures continuous work without bumping and having to stop to adjust the spool. The sweeper is light and powerful and easily clears debris from hard surfaces like patios, decks, walks, drives and garages. It is quiet and easy to start, delivering great cutting results without the mess and hassles of gas powered trimmers. Black & Decker's electric lawn and garden equipment releases zero emissions in your yard, helping to reduce your carbon footprint.
