Been following/hoping for the ultimate battery for... a few decades now I think. Donut reads as a home run of sorts. However... during those decades reading about "new tech" that promised great gains, all ended up in the dustbin of history. I really, really hope Donut is for real. Breath. Not. Holding. HTH, RF

ps: Just ordered two new dog collar lights cause the relatively new ones we had fully discharged while the mutts were outside. Now they wont charge. Jesus I hate LiOn.
