Probably because they’re new and the parent comment specifically referred to the cheaper, less energy dense battery types.

The original comment was about lithium and their popularity for backup power. Sodium ion batteries are so new that you can’t purchase them yet (blueitte supposedly released the NA300 but I can’t find any in stock and it’s no longer on their site).
It wouldn’t be fair to compare a chemistry you cannot purchase and which it’s strengths and weaknesses haven’t been tested outside of controlled laboratory testing.

Fair point - I’m not really that good with the physical sciences personally so apologies for my ignorance

You can buy them right now, there’s more links in the 18650masterrace subreddit, but here’s just one:

However good luck finding a BMS that works for it’s particular voltage range, don’t think AliExpress has any yet.
