Platforms it's compared with
We have no source saying any of these share batteries with Greenworks 40V, so owning both means two sets of packs and chargers. Each comparison lines the two platforms up tool by tool.
Same brand, different battery
Greenworks also sells Greenworks 24V, Greenworks 60V and Greenworks 80V. We have no source saying their packs fit Greenworks 40V tools, so don't assume a shared brand means a shared battery.
