This is new! The only ones available when I last looked a few months ago were mislabeled li-ion batteries. This is great, though. Thank you. EDIT: my understanding was that one of the major benefits of sodium ion batteries was their ability to discharge down to 0V. These appear to all have low voltage cutoff marks. EDIT EDIT: some available do list 0V discharge, though nothing looks like it will ship until 2024.
