Hi Sally,
It's good to hear that a major supplier has broken the $1.00/Wh barrier for the latest generation of mainstream high-tech batteries.
I am curious about the voltage that they use to rate their batteries. My Thundersky cells are rated as 3.2V and they do have a resting voltage of 3.31V three months since their last charge. But in use, the voltage usually closer to 3.1V at any regular loads. With 16 cells, I could rate my battery pack as it's resting voltage of 53V, but I use 50V to be conservative. That choice means that I rate my capacity at 8kWh instead of 8.5kWh @ 53V/pack or 8.2kWh @ 3.2V/cell. So I wonder what the specifics are around their 25.9V rating. I know that it is just a nit-pick kind of thing, but since they got so specific...
Fair winds,
Eric
