Sorry, no power

Had previously been a Bosch Keo and was with their performance also not satisfied.
Based on the reviews and because I already had the batteries I ordered the Makita.
Unfortunately, it has even less power than the Keo.
The processing of the device is very good, as the rough blade Journal of Keo was better.
When cutting a one-way pallet, the machine has become very distressed, by 7 sections of the battery was empty.
Thin, fresh branches with approx 4 cm have been overwhelmed, I'm better off with the lopper.
Have they returned and will probably take a 18 V from Bosch.
