States upto 8,4v, ie 2S lipo. That said 12T, even in a bigger 550 motor sounds too low to me for a 1/10 4WD, even a plastic fantastic arrma, however that's what Horizon ship them with so it must be ok..
If you want to try a cheaper alternative with higher number of turns, this FTX one is a 15t, so should produce more torque, and although not stated I and I believe many have used 2s lipos in them.
