Compare that to trying to fix an electric mower, or even source replacement parts for it.
Battery cells can be replaced with basic soldering skills, brushes are easy to replace, and on a brushless motor like you're likely to find in more modern mowers basically the only wear component is is the bearing. A high enough power ECU will be a bit pricy, but far from impossible to source and it really shouldn't need replacement for decades if you store the mower reasonably.
