Hello,

Hope you are well.

Your temperature protection cut off is set correctly, that is the Max temp for that setup recommended by the manufacturer.

First thing to check is your spur/pinion gear mesh. If it is too tight you will overheat. Rock the spur gear with your finger back and forth, there should be a little play. If it is too tight adjust your motor mount position. After adjustment rotate the spur gear a complete 360 degrees to check if it binds anywhere in its range. If it does, readjust. Make sure the spur is not damaged also.

If your mesh is set then read on.

When dealing with heat it is about the size of your tires and your gear ratio vs the surface you are running on combined with the efficiency of your motor and esc combo.

Grass and Sand will overheat your setup much more quickly than hard packed dirt or a paved surface.

For running on grass vs pavement a good starting point is to go down 2 teeth on your pinion then test your temperatures.

Putting larger tires on will necessitate lowering your gear ratio to compensate. Are the new tires larger in diameter, or heavier, than what was on your vehicle before?

For larger tires go down 1 or 2 teeth on your pinion gear and test your temperatures.

If none of this helps your heat situation, you could be binding somewhere else in the drive train. Disconnect the motor from the drive train and push the vehicle, does it roll smooth or does it have resistance somewhere in the roll? If so, you could have a damaged differential or a binding drive shaft. Check all of your drive shafts to the wheels and center, usually it is one of the front drive shafts that will get bent and start binding. Check all of your differentials for damage and proper fluid levels.

Your high output batteries are not causing the problem, they just allow your ESC to draw upon more power when it needs it.

Hope this helps.

Later,

Tony
