Luckily Ego has stuck with the same 56 volt batteries, just offering them in different capacities but all interchangeable. When they need more, they just take more of them; my pressure washer requires two batteries, and their riding lawn mowers take four.

The limit of that, however, is that they can’t make small devices, so I have to use a different ecosystem for things like drills, drivers, and sanders. But Ego is so much better than the alternatives for lawn care that it’s worth the extra chargers.
