Also isn't lead acid heavy as fuck for the energy stored? The difference there is more noticeable on a bike.
It's heavy and bursty. It's really not great for sustained energy discharge, which is why it's used as a starter and not for hybrid engines at runtime.
I'm hoping sodium ion takes over the ebike market. It's less energy dense then the very best lithium batteries, but most ebikes aren't using the very best lithium batteries, anyway. They're cheaper and alleviate the safety concerns (which are mostly overblown, anyway).
Yeah, I'd totally buy a sodium ion battery. I think they have something like 75% the energy density per mass vs lithium ion, which is totally fine for my use case (commuter).
