Qs about batteries in a e-Revo

[loa]

Thanks Sammus!

So the 4s 4000 20C would have as much power but would have roughly half the runtime as the 4s 8000 10C.

Ok. Another related question: what range of speeds should I expect with a 80amps battery in a e-revo using MM and 9XL?

Nothing specific as I know it relate to the gearing, but I'd like to have a revo that reaches somewhere around 35mph.

Does anyone know if the 4s 8000 10C can achieve that?

Thanks,

Loa
