Should I buy a bare tool or a kit with battery and charger?

If you already own batteries on a platform like DEWALT 20V MAX or EGO 56V, bare-tool listings save money. If you're starting fresh, kits such as the Greenworks 40V and WORX Nitro bundles include battery and charger and are usually the better value, though reviewers caution that the smallest included 2.0Ah batteries limit runtime.
