Where I work, we went to a factory. It had a huge range of large hedge trimmers, which in my opinion are among the most difficult in terms of border trimming. With a 2.5 A battery, it lasted half an hour. Then I used a 4 A and after 40 minutes it only lost one bar. It struggled slightly only on branches with a diameter of 2.5-3 centimeters that it cut. It performed much better than I expected, really. I saved a lot of gasoline, a lot of smell, and it is very lightweight. If the blade is cleaned and oiled in a timely manner, there is no problem.
