The lawn I care for is on a 1 acre lot, with lots and lots of deciduous trees. I'd love to be able to be able to use the backpack blower to clear fall leaves on the property here in turbo mode, continuously. I figure I'll need three rapid chargers, three 7.5 Ah batteries and one 2.5 Ah battery to do that (based on EGO's estimation that you can run the backpack blower in turbo mood for 27 minutes with the 7.5 Ah battery). I've read people's comments about how they don't like that on the backpack blower you need to hold the turbo button down the whole time you want to use it and there's no way to lock the button down. So, I'm wondering if it's so uncomfortable to hold that button down for a long time that you wouldn't really want to try to run it in turbo mode for, say, an hour and half or two hours, holding that button down the whole time. If you've got the backpack blower and can speak to this question, I'd love to hear your reply. Thanks!
