The 5s will offer more power and runtimes, plus it will spin the 9xl closer to optimum max rpm. If the esc can handle 5s I would say go for it. There is quite a difference between the power and temps between 4s and 5s. Plus your gearing will put more load on the motor with 4s, assuming you want the same top speed with both combos.
