minus-squareEmperorHenry@discuss.tchncs.delinkfedilinkEnglisharrow-up22·1 year agoAs a flashlight enthusiast, I’d be very interested to see if sodium batteries are any better.

minus-squarecmnybo@discuss.tchncs.delinkfedilinkEnglisharrow-up8·1 year agoThere are cylindrical cells available. The capacity is pretty low, 18650 cells are around 1.5AH and 26700 cells are around 3.5AH. They discharge down to 1.5V, so you will get less capacity if you use them in something designed for lithium cells.
minus-squareEmperorHenry@discuss.tchncs.delinkfedilinkEnglisharrow-up5·1 year agoWell I’m all about developing new technology and allowing the very best to sell the most. Maybe someday in the future there will be an alternative to lithium batteries that really is better. But as you said, Sodium batteries aren’t as good.

Just make a flat battery and roll it up. 🧌
