The Exceptional Value index combined with the 36 brand strength from LiTHELi and an Average Performance rating is a balanced purchase. The Number of Batteries of 2 count is above the 1.56 and means you should be able to swap packs instantly or benefit from double the runtime without returning to the garage, while on the lower end the Total Run Time is below the class average and may mean you will likely struggle to finish a standard suburban lot without stopping to swap batteries or recharge.
