I have mowed multiple times, checking battery use and motor temperatures.
Easy to get 3/4 acre on a charge, which is either front or rear yard. Extra batteries probably wouldn’t be advantageous. If I added enough for whole yard, weight and location becomes an issue, any less seems pointless as I would need to charge to complete entire yard anyway.
I mow in the morning, plug in and mow in the evening.
I’m not running a race, and I can live with it.
The added fan has helped, lowering temperature around 40 degrees all around. Motor is 135 at finish and adjacent batteries 104. I just have to keep the fan intake clear of grass clippings.
The machine isn’t whisper quiet, idlers and hydraulic pump make a bit of noise, but deck noise is the major sound generator.
