Nick,you were asking about weight against voltage and thinking about running 2 (2s2p) in series, i would say is that if you ran 20 gp2200s this would give you the best of both worlds since the weight is very similar and the voltage much higher.Would 20 gp2200s and a 9XL cost much more than the lipos?

Also,running a single 4s pack or a pair of 2s1p with your 7xl would half that battery weight and charging time and still give you a fair runtime.Although much less power than 24 volts.
