I also have a 18V craftsman I bought 11 years ago and it will still rip your arm off in low gear LOL. But the thing weighs like 10LBS and I'm down to one battery for it. Lowes has some weird kits I went in to by the old man a battery for his dewalt impact they wanted $80 for one. But had two for sale for $90. Then I was like I want an impact too. they had one for $220 but right next to it the bundle pack I got for $220 not sure why they do that but I wanted the saw any way so Wining Epic wining
