oh ok. so the 9xl has more run time than the 7xl, and it can also handle more cells than the 7xl? i see:). thanks for clearing that up for me :).

I might get a 7xl and a 9xl when i go brushless and use the 7xl for bashing at the park and doing jumps, and use the 9xl when im at home or dont need the extra speed but will be nice to have extra run time. good idea or not?
