The higher voltage lawn care product lines typically have much larger batteries that are not strained doing a modest urban yard.
When we moved into a new in city home a few years ago, I wanted to keep things quiet and electric. I bought a ryobi leaf blower and lawn mower, with four 40v 6.0ah batteries. Our lawn is neither small nor big - not sure on sq ft but it’s far from huge. It takes me about 6-8 gull charges to complete mowing and blowing. Leaf blowing is by far the more energy intensive.

I pretty much never need to recharge the batteries when working. I haven't needed to do much maintenance to it at all, just sharpening the mowing blade. Even after a few years the batteries still have plenty of charge to mow, trim, edge, and blow both yards. I don't normally have enough battery to do all that and do the hedge trimmer for a while though, I'll normally go inside and cool off for 15-20min and then go back out if I need to handle that. The fast charger can get a pretty good charge in 20 minutes
