I think the lithium ship is now too big to turn around , still the best lightest cleanest with no need to change electrolyte etc , basically plug and play ,
By the the time the battery starts to fade in fifteen years they will already have invented a fix. Maybe in the the form of a recon just like your car engine. Oh and don't forget no pollution and for that my kids won't mind paying for a refit for another fifteen years.
At 73 I may not need a recharge to the battery pack I will fit to my house , forget about cars and bikes etc the future for lithium is in storage domestic and commercial, I feel sure I am correct, so sit back and enjoy the ride.
