Bro, a lot of shit was still using NiMh batteries in 2003. I know a lot of the advancements haven’t been very sexy, but charge discharge cycle count, energy density, rapid charging, high wattage discharge, these are all important. I’m going to stay hopeful.
The sodium 18650s are available on Alibaba for a few weeks :)
And for re-use my “extra” batteries are all interchangeable or able to be put to use elsewhere when the bike isn’t in use. ( I’ve been considering an inverter for power outages).
I mean you personally may be able to reuse them, but most people just throw their old escooter (or whatever) away when they get a new one, or at best resell it or donate it.

New battery tech in the next 5 years is hopefully going to make lithium ion obsolete. Fingers crossed.
I’ve been hearing that my whole life and it hasn’t actually improved much in the last 20. But yeah it would be great if you’re right.
But smart BMS with easily user-replaceable batteries is tech we could use today. Furthermore you can buy packs like that off aliexpress right now.
Also, wanting to reuse batteries from an old device after upgrading will always be a problem.

Btw what are sodium 18650s? A new safer version?
Cheaper ( like 1/3? ), last longer ( more discharge /charge cycles ), can safely drain to 0.
Wtf that sounds awesome, any downside?
Iess dense energy storage ( bigger size ).
