I got the kit done in Aldi (petrol) and then the kit done in Lidi (battery) both on a long pole, both have a short chain saw and a hedge cutter, the Lidi one had two types of grass cutters the strimmer and blade, the Aldi has a blower found both good, but the battery one is lighter seems just as strong as the petrol one, got 4 batteries it uses 2 at a time, and charger takes an hour to recharge a pair, and the strimmer will flatten a pair in an hour, so no real limit.
Both are unwieldy being on end of pole, but can cut hedge without a ladder, the old Aldi hedge cutter electric mains is easier with low stuff, but getting cables out is a pain, so tend to use the one on pole for all, with strimmer attachment needs the harness which came with both, but cutting hedge it does not really carry the weight.
The chain saws are called a lopper, and are too small to cut down large trees, but work well with thick branches. The petrol does start easy, but the weight is the problem, and going to get two stroke. So now I have the battery one, the petrol one is hardly used.
