Will this N-Channel Mosfet work as high-current motor controller?
If you use L298 then a protection against the stall current is needed, "over current protection".

And the stall current 2 x 11.5A have to be checked against the C rating on the LiPo batteries so you don't overload the batteries. Look for "Discharge rate characteristics" for your battery type.

And @Dwayne Reid s comment about 4 transistors per motor is also known as a H-bridge, ref.: https://en.wikipedia.org/wiki/H_bridge

And 14 Watts is rated at 12V not 11.1V. So calculate the resistant for the motor and then you can calculate the watt at 11.1V.
