Gag, splutter. 20Ah means 20A for 1 hour. There is no way I'm having
something consuming 20A loose in my garden! Similarly, a two 4A motors
are going to do serious damage if pointed in the wrong direction.
I think you can reduce the figures to 1A for each motor and a generous 2A
for cutting. 4A is still higher than I'd like, but a bit more reasonable!
