Chris,
I have a 236v Electric rotavator/tiller. I was dubious when I bought it, it turns out I was wrong. It will run for about 30 mins and because of the torque from the motor it will cut through roots and things that would have clogged a similar sized petrol version. 30 mins is enough for me, but I can accept for some that a second battery set would be needed.
I have an elderly, but functional ride on mower. When it dies it will be replaced by an electric one.
All my workshop power tools are battery, as is my daily drive.
Are Lithium Ion batteries the future? I have no answer, but they are quiet and need less faffing about with.
Do they make financial sense? Depends how you configure a lifetime discounted cash flow but if you run a DCF on garden tools and workshop tools you probably need help.
