Now here is something Really Wild
EGO has a BackPack PowerLink for their hand tools
You wear your Battery in a backpack harness and it has a 5'9" Cable with a "dummy head" battery receptacle you plug into the tool where the real battery would go.
They have batteries up to 7.5Ah
Those EGO people are really going all the way above and beyond.
That would make one of the chainsaws feather-lite.
And - it's ONLY $180 extra !
They also have power converters where you hook in 4 of their batteries to this digital box and use it like a gas powered generator.
If you gots the moneys they gots the goodies
