You do know you will never reach this power density number. First, 130C battery performance will never be the same from brand to brand. Secondly, at 130C your connectors and wires will be so hot that it would be burning the insulation right off, so don't use the burst current ratings... ever. Thirdly, the voltage drop at 130C will be so astronomical that it would make it noting short of useless in any application. The max ratings for batteries these days should only be the continuous C rating, which is 65C for those nano-techs. Compared to the cell IR of other top brands such as ThunderPower and Hyperion, nano-tech packs are very overrated.

That is almost twice the ratio of "MaxPuffs" 150C bateries or GensAce 120C

I cant believe this. The highest power to weight ratio battery I found on Wikipedia is 21kW/kg

Another weird thing is that other A-spec batteries are around the same as other brands:

A-spec 6S 5Ah 65-130C = 19.5kW/kg
GensAce 6S 5.3Ah 60-120C = 20kW/kg
MaxAmps 6S 5.45Ah 150C = 23.7kW/kg
