With the advent of Lithium batteries and I use them on my boat for trolling motor and electronics hard to beat.
The unit performed well cleaning off 4 bigger driveways but Need at least 4 40 volt batteries as you get about 2 hours of blowing Snow...its light, quiet and rugged...I like it, i have a 28" 2 stage which is now just used for heavy and deep snow...Keep up the good work RYOBI
