But thats an unfair comparison, just because lots of people choose the 8000 doesnt mean you can evenly compare 6s 8000 to 12s 2200. Looking at the power each pack provides (taking 3.7v nominal cell v) thats about 177Wh from the 6s and under 100Wh from the 12s, of course the 12s will be smaller and lighter...

And on top of that, I've noticed people tend to choose th 8000 for 3s and 4s setups, and then 4 or 5000 for 6s...
