You're talking about an 18V battery, maybe up to 8Ah. About 144Wh.
My batteries on my blower and trimmer and lawn mower use 56V batteries, up to 12Ah. About 672Wh. The smallest battery I have for it is 280Wh.
Milwaukee might make some decent power tools, but they're still batteries designed for a drill or some other smaller handheld tool used for short stints. Companies focusing on lawn care products have much different battery packs.
