No experiences, but I've been looking at their cells too. For any kind of decent capacity like ~15Ah (for those of us who want to run under 2,000v

), you'd need to parallel a bunch of the 26650 cells, times that by the s count and you get quite a wiring job! Personally, I'd like a 1p pack whenever possible.
That said, the 32113 cells (4.4Ah) have less than double the capacity, but more than double the weight (205g) of the 26650 cells. The prism 20Ah cell, even though it's almost 500g, would be worth it in terms of wiring simplicity and only 1p setup. Not to mention the prism cells would have less wasted space. I wonder how much they are per cell (if we could even get raw cells)?
