Finished the lawn... I even survived ( it was about 95° )... 
I did most of the trimming on low speed and just a little of the edging part on high... Trimming it didn't seem to matter high or low, edging is certainly easier on high. I started with the trimming/edging first and after that, while mowing, I put the battery back on the charger for later when I was going to use the blower. I just barely got everything on one battery ( with a charge and a half ) ... just as I was finishing the last of the sidewalks... it ran down. This is using a 4ah battery, so I'll order a 5ah and should have more than enough even if I run on high all though the trimming.
