I recently bought a kobalt 40v pole saw. That thing is badazz, I've used it 3 or 4 times and I've worn out long before the battery every time
I had enough gift cards at Christmas I bought the 80v. It is a bad unit! I used it a ton with my lawn care business and I'm still on the original charge. It's about ready for a charge now but i cant believe how long it's lasted.
