I have. It sucks but it’s possible and because I live in a mountainous area I avoid that problem by using less assist so everything lasts longer.
The broader point I was trying to make is that If you’re trying to allocate the limited raw materials to the types of transport that benefit people the most then pushing e-bikes to lead acid makes a lot of sense. Yeah, the bikes could benefit from a more power dense battery, but they have backup pedals and ultimately their rider is the majority of the loaded bikes weight.
Electric cars and trucks weigh at least ten times what a person does and are generally used for longer distances than e-bikes so it makes more sense to use very energy dense batteries in them.
Again, I’m speaking from a position that recognizes the proliferation of electric vehicles in China and recognizes that the raw materials used to make lithium batteries are finite and in high demand, not from the position of trying to optimize the e-bike.
Anyone who actually has done that knows that it always ends up swinging around and ending up in the spokes if you go fast enough.
Also 5 lbs is not a big deal when it’s detachable, but it matters a lot more when it’s part of a large 30+ lb object you’re carrying up the stairs to your apartment.

Seems like cars don’t all need 300 mi range, but a 5 lb weight difference in a bike is huge.
Five pounds is the grocery bag dangling off my flat bar.

Wait so would you leave your groceries outside while you carried in your bike?
Personally I use a backpack ever since the groceries in the spokes incident
So you carry the groceries upstairs at the same time as your bike?
Have you heard of torque by happenchance?
How much does torque come into play when you’re carrying your bike upstairs?
