i have octopus go. march 2022 version it is going up as they’re ending it but currently i get 4 hours of electricity between 00.30 and p4.30 hrs 7 days a week which means I can get 324 miles in my kona for £4.80.
All i do is charge for 8 hrs over two nights. it’s never near zero miles so i don’t have run into a third night.
