Top notch! Like you, I had fears for the battery and power! For power no worries, slow down in the tall grass as for heat but it always happens! Same for the first mowing of spring !! For the battery I have a large garden of +/- 400m². It comes out easily. If it's all the 2 weeks will be sufficient. For grass longer time you empty the second will be the first battery charge enough to finish. live fast charging! As for the price ... a real good mower with a Honda engine costs around 800 euros .... so compare what comparable es t!
