This is totally normal.
Any motor running off a MOSFET and LiPo is going to run way hotter than normal.
With an 11.1v LiPo, your not only getting more voltage than a 9.6v battery, but your also getting WAY more amperage. More power going to the motor = more heat.
The active braking also adds more heat since it forces the motor to work harder. Since it's heating up so much, your going to have to worry about your SW-COMP shutting off due to heat as well, it happened to me frequently before tuning my motors, and happened constantly on my 249 until DonP built me a bigger SW-COMP.
The LiPo doesn't mind it at all, it's just your wiring, motor, and SW-COMP that are heating up.

Honestly the only 2 ways you can fix the problem is to either put less voltage through the motor, or tune up the motor.
You'll have to balance it, get high quality brushes and set your spring tension to insure the motor is using the minimum amount of amperage for it's maximum amount of power.

By example, I've done this to several G&P M140's, a systema magnum and G&P M120
The magnum was highest at 12A, and the G&P was trailing at 8A before tuning. After tuning the magnum was at 8A, and the M140's were drawing 4.25A

They all ran significantly cooler afterwards.

With an SW-COMP your going to be able to REALLY tell how high quality your motors are, good luck even trying to run a systema magnum without modifying it lol
All 4 guns I've seen with SW-COMPs and magnum motors were plagued with overheating issues.
