Hi Mike,
I have the Stihl leaf blower with the professional range AP batteries. Have a major leaf collection task in the autumn with a massive copper beech and poplar plus many other trees. A stacked P6e with mesh sides is not sufficient to dump all the (bagged & compressed) leaves in one trip. It replaced a petrol Stihl blower / vacuum. Its amazing, so much better than the petrol product, as it is instant on or off, lighter, no fumes and great power control on the trigger that is v.important for making the job easier. One 'small' AP200 battery lasts long enough to do enough leaves to charge itself while I am packing the leaves in bags, although I have two batteries so am covered anyway. Great choice if you are ready to buy into the Stihl electric tools ecosystem as the batteries can be used across the range. If you have already invested in another premium manufactures' battery system then maybe stick with that!
